Neuraminidase (also known as sialidase, acylneuraminil hydrolase and EC 3.2.1.18) is a common enzyme in animals and some microorganisms. It is glycohydrolase to cleave terminal alpha-ketosidically linked sialic acid from glycoproteins, glycolipids and oligosaccharides. Many microorganisms containing neuraminidenis cause disease in humans and poultry, horses, pigs, and other animals, including seals. Organisms having N-acetylneuramidase include Vibrio cholerae, C. a. C. perfringens and Streptococcus sp. Bacteria such as (Streptococcus sp.) And viruses such as influenza viruses and parainfluenza viruses.
Influenza neuraminidase has been implicated in the pathogenicity of the influenza virus. It is believed to help release the newly synthesized virion from infected cells and to help the virus move through the respiratory mucosa (via its hydrolase activity).

The R _6a and R _6b groups are not important functional groups and can vary widely. If not H, their function is to serve as an intermediate to the parent drug substance. This does not mean that they are biologically inert. In contrast, the main function of these groups is to convert the parent drug into prodrugs, thereby releasing the parent drug upon conversion of the prodrugs in vivo. Since active prodrugs are absorbed more effectively than the parent drug, they actually have greater activity in vivo than the parent drug. If R _6a and R _6b are not hydrogen, they are removed ex vivo for chemical intermediates or in vivo for prodrugs. It is generally more preferred if the product is generally pharmaceutically harmless, but it is not particularly important that the resulting pro-functional product, such as an alcohol, will be physiologically acceptable, along with the chemical intermediate.

Protecting groups (hydroxy, acid or other functional groups) for —OH functional groups are embodiments of “ether- or ester-forming groups”.
Of particular interest are ether- or ester-forming groups which can function as protecting groups in the schemes presented herein. However, some hydroxyl and thio protecting groups are not ether-forming groups or ester-forming groups as will be understood by those skilled in the art and are included in the amides discussed under R _6c described below. Since R _6c can protect hydroxyl or thio groups, hydroxyl or thio is produced by hydrolysis from the parent molecule.
In the role of ester-forming, R _6a is generally bound to an acidic group such as, but not limited to, a -CO ₂ H or -C (S) OH group to yield -CO ₂ R _6a . R _6a can be deduced, for example, from the esters described in WO95 / 07920.

As a further embodiment, Table A provides examples of R _6a ester moieties that may be bonded to the —C (O)) — and —P (O) (O—) ₂ groups, for example via oxygen. Some R _6c amidates directly attached to —C (O) — or —P (O) ₂ are also shown. The esters of the formulas 1-5, 8-10, and 16, 17, 19-22 have free hydrides and the compounds of the present invention have corresponding halides (such as chloride or acyl chloride) and N, N-dicyclohexyl-N It is synthesized by reacting morpholine carboxamidine (or a base such as DBU, triethylamine, CsCO ₃ , N, N-dimethylaniline, etc.) in DMF (or a solvent such as acetonitrile or N-methylpyrrolidone). If W ₁ is a phosphonate, the esters of structures 5-7, 11, 12, 21 and 23-26 are monochlorophos to alcohol or alkoxide salts (or the corresponding amines for compounds such as compounds 13, 14 and 15) Synthesized by reacting with phonates or dichlorophosphonates (or other activating phosphonates).

Examples of such useful R _6a groups include alkylacyloxymethyl esters and derivatives thereof such as:

For prodrug purposes, the esters generally selected are antibiotic drugs, in particular cyclic carbonates, double esters or phthalidyl, aryl or alkyl esters.
As will be appreciated, the groups R _6a , R _6c and R _6b serve as protecting groups (PRTs) in synthesis since they can optionally be used to prevent side reactions with protecting groups during the synthesis process. In most cases the decision of which group to protect and the nature of the PRT will depend on the chemistry of the reaction to be defended (eg, acidic, basic, oxidative, reductive or other conditions) and the intended synthesis direction. If the compound is substituted with a plurality of PRTs, the PRT groups need not be identical to one another and are generally not identical. Generally, PRTs will be used to protect carboxyl, hydroxyl or amino groups. The order of deprotection to produce free radicals will depend on the intended synthesis direction and the reaction conditions to be encountered and can occur in any order determined by those skilled in the art.

In particular Chapter 1, Protecting Groups; An Overview, pp. 1-20, Chapter 2, Hydroxyl Protecting Groups, Pages 21-94, Chapter 3, Diol Protecting Groups, Pages 95-117, Chapter 4, Carboxyl Protecting Goroups, pp. 118-154, Chapter 5, Carbonyl Protecting Group See pages 155-184. See Greene described below for R _6a carboxylic acid, phosphonic acid, phosphonate, sulfonic acid and other protecting groups for W ₁ acid. Such groups include, but are not limited to, esters, amides, hydrazides, and the like.
In some embodiments the R _6a protected acidic group is an ester of an acidic group and R _6a is a residue of a hydroxyl-containing functional group. In another embodiment, the R _6c amino compound is used to protect acid functionality. Residues of suitable hydroxyl or amino-containing functional groups have been described above and are also disclosed in WO95 / 07920. Of particular interest are amino acids, amino acid esters, polypeptides or aryl alcohol residues. Typical amino acid, polypeptide and carboxyl-esterified amino acid residues are described as L ₁ or L ₂ in WO95 / 07920 pages 11-18 and related parts. Although WO 95/07920 discloses amidates of phosphoric acid clearly, it should be understood that such amidates can be produced using any of the acid groups set forth herein and the amino acid residues set forth in WO 95/07920.
Typical R _6a esters for protecting W ₁ acid functionality are also _shown in WO95 / 07920 and it will be appreciated that the same ester can be formed using the same acidic group as the phosphonate of the '920 publication. General ester groups are defined in at least WO95 / 07920 89-93 (under the definition of R ³¹ or R ³⁵ ), table 105, page 21-23 (as R). Of particular interest is unsubstituted aryl such as phenyl or benzyl or hydroxy-halo-, alkoxy-, carboxy- and / or alkylestercarboxy-substituted aryl or alkylaryl, arylalkyl, in particular phenyl, ortho-e. Oxyphenyl, or an ester of C _1-4 alkyl estercarboxyphenyl (salicylate C _1-12 alkyl ester).
The protected acidic groups W _1, W ₁ in the case, especially with the esters or amides of WO95 / 07920 is useful as prodrugs for oral administration. However, the W ₁ acidic group does not necessarily have to be protected to effectively administer the compounds of the present invention by the oral route. When systemically or orally administered compounds of the invention having protecting groups, especially amino acid amidates or substituted and unsubstituted aryl esters, they may be hydrolytically cleaved in vivo to produce free acid.
One or more acidic hydrolysis is protected. If more than one acidic hydroxyl is protected, the same or different protecting groups are used, for example the esters may be the same or different and mixed amidates and esters may be used.
Typical R _6a hydroxy protecting groups described in Greene (pp. 14-118) include ether (methyl); Substituted methyl ether (methoxymethyl, methylthiomethyl, t-butylthiomethyl, (phenyldimethylsilyl) methoxymethyl, benzyloxymethyl, p-methoxybenzyloxymethyl, (4-methoxyphenoxy) methyl, sphere Iacolmethyl, t-butoxymethyl, 4-pentenyloxymethyl, siloxymethyl, 2-methoxyethoxymethyl, 2,2,2-trichloroethoxymethyl, bis (2-chloroethoxy) methyl , 2- (trimethylsilyl) ethoxymethyl, tetrahydropyranyl, 3-bromotetrahydropyranyl, tetrahydrothiothioranil, 1-methoxycyclohexyl, 4-methoxytetrahydropyranyl, 4-meth Oxytetrahydrothiopyranyl, 4-methoxytetrahydratethiopyranyl, S, S-dioxido, 1-[(2-chloro-4-methyl) phenyl] -4-methoxypiperidin-4-yl , 35, 1,4-dioxan-2-yl, tetrahydrofuranyl, tetrahydrothiofuranyl, 2,3,3a, 4,5,6,7,7a-octahydro-7,8,8- Trimethyl-4,7-methanebenzofuran-2-yl)); Substituted ethyl ether (1-ethoxyethyl, 1- (2-chloroethoxy) ethyl, 1-methyl-1-methoxyethyl, 1-methyl-1-benzyloxyethyl, 1-methyl-1-benzyloxy 2-fluoroethyl, 2,2,2-trichloroethyl, 2-trimethylsilylethyl, 2- (phenylselenyl) ethyl, t-butyl, allyl, p-chlorophenyl, p-methoxyphenyl, 2 , 4-dinitrophenyl, benzyl); Chihoned benzyl ethers (p-methoxybenzyl, 3,4-dimethoxybenzyl, o-nitrobenzyl, p-nitrobenzyl, p-halobenzyl, 2,6-dichlorobenzyl, ㅔ -cyanobenzyl, p- Phenylbenzyl, 2- and 4-picolinyl, 3-methyl-2-picoli N-oxido, diphenylmethyl, p, p'-dinitrobenzhydryl, 5-dibenzosuberyl, triphenylmethyl, α-naphthyldiphenylmethyl p-methoxyphenyldiphenylmethyl, di (p-methoxyphenyl) phenylmethyl, tri (p-methoxyphenyl) methyl, 4- (4'-bromophenacyloxy) phenyl Diphenylmethyl, 4,4 ', 4 "-tris (4,5-dichlorophthalimidophenyl) methyl, 4,4', 4" -tris (lebulinoyloxyphenyl) methyl, 4, 4 ', 4 " -Tris (benzoyloxyphenyl) methyl, 3- (imidazolyl-1-ylmethyl) bis (4 ', 4 "-dimethoxyphenyl) methyl, 1,1-bis (4-methoxyphenyl) -1' -Pyrenylmethyl, 9-A-anthryl, 9- (9-phenyl) zantenyl, 9- (9-phenyl-10-oxo) anthryl, 1,3-benzodithiolan-2-yl, benziso Thiazolyl, S, S-dioxido); Silyl ether (trimethylsilyl, triethylsilyl, triisopropylsilyl, dimethylisopropylsilyl, diethylisopropylsilyl, dimethyltecsilyl, t-butyldimethylsilyl, t-butyldiphenylsilyl, tribenzylsilyl, tri-p Xylylsilyl, triphenylsilyl, diphenylmethylsilyl, t-butylmethoxyphenylsilyl); Esters (formate, benzoylformate acetate, dichloroacetate, dichloroacetate, trichloroacetate, trifluoroacetate, methoxyacetate, triphenylmethoxyacetate, phenoxyacetate, p-chlorophenoxyacetate, p-poly- Phenylacetate, 3-phenylpropionate, 4-oxopentanate (levulinate), 4,4- (ethylenedithio) pentanoate, pivalate, adamantatoate, crotonate, 4 -Methoxycrotonate, benzoate, p-phenylbenzoate, 2,4,6-trimethylbenzoate (mesitoate)); Carbonates (methyl, 9-fluorenylmethyl, ethyl, 2,2,2-trichloroethyl, 2- (trimethylsilyl) ethyl, 2- (phenylsulfonyl) ethyl, 2- (triphenylphosphonio) Ethyl, isobutyl, vinyl, allyl, p-nitrophenyl, benzyl, p-methoxybenzyl, 3,4-dimethoxybenzyl, o-nitrobenzyl, p-nitrobenzyl, S-benzyl thiocarbonate, 4 Ethoxy-1-naphthyl, methyl dithiocarbonate); Groups With Assisted Cleavage (2-iodobenzoate, 4-azidobutyrate, 4-nitro-4-methylpentanoate, o- (dibromomethyl) benzoate, 2-formylbenzenesulfonate, 2- (Methylthiomethoxy) ethyl carbonate, 4- (methylthiomethoxy) butyrate, 2- (methylthiomethoxy) ethyl carbonate, 4- (methylthiomethoxy) butyrate, 2- (methylthiometh Oxymethyl) benzoate); Other esters (2,6-dichloro-4-methylphenoxyacetate, 2,6-dichloro-4- (1,1,3,3-tetramethylbutyl) phenoxyacetate, 2,4-bis (1,1 -Dimethylpropyl) phenoxyacetate, chlorodiphenylacetate, isobutyrate, monosuccinoate, (E) -2-methyl-2-butenoate (Tigoloate), o- (methoxycarbonyl) benzoate, p Poly-benzoate, α-naphthoate, nitrate, alkyl N, N, N'N'-tetramethylphosphorodiamidate, N-phenylcarbamate, borate, dimethylphosphinothiolyl, 2, 4-dinitrophenylsulfenate); And sulfonates (sulfates, methanesulfonates (mesylate), benzylsulfonates, tosylate).

Amide-forming R _6b is for example found in the G ₁ group.

More generally, protected amino groups include carbamates and amides, more generally -NHC (O) R ₁ or -N = CR ₁ N (R ₁ ) ₂ . Another protecting group that may be usefully used as a prodrug at the G ₁ position, particularly for amino or b-NH (R ₅ ) is:

See, eg, Alexander, J. et al., "J. Med. Chem." 39: 480-486 (1996).
R _6c is H or an amino-containing compound, particularly an amino acid, polypeptide, protecting group, -NHSO ₂ R ₄ , NHC (O) R ₄ , -N (R ₄ ) ₂ , NH ₂ or -NH (R ₄ ) (H) As a residue of, for example, a carboxyl or phosphonic acid group of W ₁ reacts with an amine to form -C (O) R _6c , -P (O) (R _6c ) ₂ or -P (O) (OH) (R _6c To form an amide. In general, R _6c has the _structure of R ₁₇ C (O) CH (R ₁₆ ) NH— where R ₁₇ is OH, OR _6a , OR ₅ , amino acid or polypeptide residue.
Amino acids are lower molecular weight compounds of less than approximately 1,000 MW and contain at least one amino or imino group and at least one carboxyl group. In general, amino acids may be found or searched in nature, ie, among biological substances such as bacteria or other microorganisms, plants, animals or humans. Suitable amino acids are alpha amino acids, ie compounds characterized by one amino or imino nitrogen atom separated from a carbon atom of one carboxyl group by a single substituted or unsubstituted alpha carbon atom. Of particular interest are hydrophobic moieties such as mono- or di-alkyl or aryl amino acids, cycloalkylamino acids and the like. These residues contribute to cell permeability by increasing the fractionation of the parent drug. Generally, residues contain sulfhydryl or guanidino substituents.
Naturally-occurring amino acid residues are found in plants, animals or microorganisms, in particular their proteins. Polypeptides are the most representative examples of these naturally occurring amino acid residues. These amino acids are glycine, alanine, valine, leucine, isoleucine, serine, threonine, cystine, methionine, glutamic acid, aspartic acid, lysine, hydroxylysine, arginine, Histidine, phenylalanine, tyrosine, tryptophan, proline, asparagine, glutamine and hydroxyproline.
When R _6b and R _6c are single amino acid residues or polypeptides they are usually substituted with R ₃ , W ₆ , W ₁ and / or W ₂ , and generally only with W ₁ or W ₂ . These conjugates are produced by forming an amide bond between the carboxyl group of an amino acid (or such as the C-terminal amino acid of a polypeptide) and W ₂ . Likewise, a conjugate is formed between the amino group and W ₁ of an amino acid or polypeptide. Although it is within the scope of the present invention to introduce an amino acid at one or more allowed sites, only one site of the parent molecule is amidated with the above-mentioned amino acids. Generally, the terminal amino group or carboxyl group of the polypeptide or the α-amino group or α-carboxyl group of the amino acid is bonded to the parent functional group, ie the carboxyl or amino group in the amino acid side chain is generally not used to form an amide bond with the parent compound (although Although these groups need to be protected in the synthesis of the conjugate as described below).
With respect to the carboxyl-containing side chain of the amino acid or polypeptide, it will be understood that the carboxyl group is optionally blocked, for example by R _6a , esterified by R ₅ or amidated by R _6c . Likewise, the amino side chain R ₁₆ will optionally be blocked with R _6b or substituted with R ₅ .
Like esters or amides and parent molecules, the side chain amino or carboxyl groups and such ester or amide bonds are optionally hydrolysable under acidic (pH <3) or basic (> pH 10) conditions in vivo or ex vivo. On the other hand, they are actually stable in the human gastrointestinal tract but enzymatically hydrolyze in the blood or intracellular environment. Ester or amino acid or polypeptide amidates are also useful as intermediates in the preparation of oral molecules containing free amino or carboxyl groups. The free acid or free base of the parent compound can be readily produced, for example, from the ester or amino acid or polypeptide conjugates of the invention by conventional hydrolysis processes.
If the amino acid residues contain one or more chiral centers, their D, L, meso, threo or erythro (appropriately) racemates, scalemates or mixtures thereof can be used. In general, D isomers are useful if the intermediate is non-enzymatically hydrolyzed (as is the case with amides as chemical intermediates in free acids or free amines). Conversely, L isomers are more versatile because they are sensitive to both non-enzymatic and enzymatic hydrolysis, and are more efficiently delivered by amino acids or dipeptidyl delivery systems in the gastrointestinal tract.

A polypeptide is a polymer of amino acids, in which a carboxyl group of one amino acid monomer is bonded by an amide bond to an amino or imino group of the next amino acid monomer. Polypeptides include dipeptides, low molecular weight polypeptides (about 1500-5000 MW) and proteins. The protein optionally contains 3, 5, 10, 50, 75, 100 or more residues and is preferably suitably sequence-homologous to human, animal, plant or microbial protein. These include not only enzymes (eg hydrogen peroxide enzymes) but also immunogens such as KLH, or antibodies or proteins against a subject to which an immune response is to be raised. The nature and identity of polypeptides can vary greatly.
Polypeptide amidates are useful as immunogens that raise antibodies to the epitope of a polypeptide (if it does not produce immunogenicity in the animal taking it) or the remaining compounds of the invention.
Antibodies that can bind to non-peptidic parent compounds can be used to isolate the parent compound from the mixture in the diagnosis or preparation of the parent compound. Because conjugates and polypeptides of the parent compound are generally more immunogenic than closely related animal polypeptides, they are more immunogenic to allow the polypeptide to readily raise antibodies to it. Thus, the polypeptide or protein may not need to be immunogenic in animals commonly used to raise antibodies, such as, for example, rabbits, mice, horses or rats, but the end product conjugate should be immunogenic in at least one of these animals. The polypeptide may contain a peptidase cleavage site optionally between a first residue and a second residue adjacent to an acidic heteroatom. Such cleavage sites are flanked by enzymatic recognition structures such as, for example, specific residue sequences recognized by peptidase.
Peptidase enzymes for cleaving polypeptide conjugates of the invention are well known and particularly include carboxypeptides. Carboxypeptides degrade polypeptides by removing C-terminal residues and are specific in many cases for specific C-terminal sequences. These enzymes and their general substrate requirements are well known. For example, the dipeptides (having free residues with a given residue pair) covalently bind to the phosphorus or carbon atoms of the compounds of the present invention. In embodiments where W ₁ is a phosphonate, it is expected that the peptide will be cleaved by an appropriate peptidase to autocatalytically cleave the phosphoamidate linkage to the carboxyl of the terminal amino acid residue.
Appropriate dipeptidyl groups (denoted in their single letter code) are as follows:

Tripeptide residues are also useful as R _6b or R _6c . If W ₁ is phosphonate, then -X ₄ -pro-X _5- (wherein X ₄ is an amino acid residue and X ₅ is an amino acid residue, a carboxyl ester of proline, or hydrogen) is assigned to the luminal carboxypeptides Is cleaved to produce X ₄ with free carboxyl, which in turn is expected to autocatalytically degrade phosphonoamidate bonds. The carboxy group of X ₅ is esterified with benzyl.
Dipeptide or tripeptide species may be selected based on sensitivity to the peptides and / or known delivery properties that may affect delivery to visceral mucosa or other cell types. Dipeptides and tripeptides lacking an α-amino group are transfer substrates for peptide carriers found in the brush border of small intestinal mucosal cells (Bai, JPF, "Pharm Res." 9: 969-978 (1991). Peptides can therefore be used to increase the bioavailability of amidate compounds Di- or tripeptides having one or more amino acids in the D configuration can also be used for peptide delivery and in the amidate compounds of the invention. Amino acids of the D configuration can be used to reduce the sensitivity of di- or tripeptides to hydrolysis by proteases common to brush boundaries such as aminopeptides N (EC 3.4.11.2). Peptides, on the other hand, were also selected based on their relative resistance to hydrolysis by proteases found in the visceral cavity. For example, polypeptides or tripeptides that bind asp and / or glu are poor substrates for Aminopeptides A (EC 3.4.11.7) and on the N-terminus side of hydrophobic amino acids (leu, tyr, phe, val, trp) Di- or tripeptides lacking amino acid residues are poor substrates for endopeptides 24.11 (EC 3.4.17) Relatively resistant or relatively sensitive to hydrolysis by cytoplasm, kidney, liver, serum or other peptides Similar criteria can be applied to selecting peptides: Such poorly truncated polypeptide amidates are useful or immunogens for binding to proteins to produce immunogens.
Stereoisomer
The compounds of the present invention are optical isomers or resolved optical isomers which are enriched in any or all asymmetric atoms. For example, chiral centers apparent from the description are provided as chiral isomers or racemic mixtures. As well as both racemic mixtures and diastereomeric mixtures, individual optical isomers that are actually separated or synthesized without their enantiomers or diastereomeric partners are within the scope of the present invention.
One or more of the methods illustrated below are used to prepare enantiomerically rich or pure isomers. This method is listed according to the order of approximate preferences, ie, those skilled in the art should typically use stereospecific synthesis from chiral precursors prior to chromatographic degradation prior to spontaneous crystallization.
Stereospecific synthesis is described below. This type of method is often used when a suitable chiral starting material is available and the chosen reaction step does not result in undesirable racemization at the chiral position. One advantage of stereospecific synthesis is that it does not produce undesirable enantiomers that must be removed from the final product, ie lower the overall synthesis yield. In general, those skilled in the art will understand what starting materials and reaction conditions should be used to produce the desired enantiomerically rich or pure isomers by steric synthesis. If unexpected racemization occurs in a method that is considered stereospecific, the following separation method should be used to obtain the desired product.
If the proper stereospecific synthesis method is not experimentally devised or determined by conventional experimentation, one of ordinary skill in the art would choose another method. A commonly used method is the chromatographic decomposition of enantiomers on chiral chromatography resins. Such resins are packed in a column, commonly called a Pirkle column, and are commercially available. This column contains the chiral normal phase. The racemates are placed in solution and loaded on a column and separated by HPLC. For example, Proceedings Chromatographic Society-International Symposium on Chiral Separations, September 3, 1987. 3-4. Examples of chiral columns that can be used to identify optimal separation techniques include Diacel Chriacel OD, Regis Pirkle Covalend Dphenylglycine, Regis Pirkle Type 1A, Astec Cyclobond II, Astec Cyclobond III, Serva Chiral DDL = Daltosil 100, Bakerbond DNBLeu, Sumipax OA-1000, Merck Cellulose Triacetate column, Astec Cyclobond I-Beta or Regis Pirkle Covalent D-Naphthylalanine. Not all of these columns are effective for all racemic mixtures. However, those skilled in the art will understand that a certain amount of screening is required to identify the most effective steady phase. When using such a column, preference is given to using embodiments of the compounds of the invention in which the charge is not neutralized, for example, in which no acidic functional groups such as carboxyl are esterified or amidated.
Another method is to convert enantiomers in the mixture to diastereomers using chiral auxiliaries and then the conjugates are separated by conventional column chromatography. This is a particularly suitable method when the embodiments contain free carboxyl, amino or hydroxyl to form covalent bonds or salts for chiral assistants. Chirally pure amino acids, organic acids or organosulfonic acids are all valuable as chiral assistants and they are all well known in the art. Salts with these auxiliaries can also be produced or they can be covalently (but reversibly) bound to functional groups. For example, pure D or L amino acids can be used to amidate the carboxyl groups of embodiments of the invention and then separated by chromatography.
Enzymatic digestion is another potentially valuable method. In this process, covalent derivatives of enantiomers are prepared in a racemic mixture, generally a lower alkyl ester (such as of carboxyl), and then the derivatives are enzymatically cleaved, usually hydrolyzed. In order for this method to be successful, it is often necessary to screen several enzymes regularly, since it is necessary to select an enzyme that can be stereospecifically cleaved. When the ester is to be cleaved, esterases, phosphatides, lyphases and the like are selected and the activity of their derivatives is measured. Typical esterases are derived from organs of the liver, pancreas or other animals, and also include pork liver esterases.
When the enantiomer mixture is separated from the solution or melt as aggregates, ie enantiomerically-pure crystal mixtures, it is possible to produce enantiomerically rich formulations by mechanically separating the crystals. However, this method is not suitable for large scale production and is of no value for true racemic compounds.
Asymmetric synthesis is another technique for producing enantiomer enrichment. For example, the chiral protecting group is reacted with the group to be protected and the reaction mixture is equilibrated. If the reaction is enantiomerically specific, the product will be enriched for that enantiomer.

Wilen (Krieger Publishing Company, Malabar, FL, 1991, ISBN 0-89464-618-4 ) But is not limited thereto.

In a typical example, these compositions bind neuraminidase with a binding index of less than 10 ⁻⁴ M, typically less than 10 ⁻⁶ M, more typically less than 10 ⁻⁸ M. If so, substantially irreversible binding compositions are useful as diagnostic probes of Neuraminidase.

Typically this sample will be assumed to contain organisms that produce neuraminidase, usually pathogenic organisms such as viruses. Samples can be contained in any medium containing water and an organic solvent / water mixture. Samples include living organisms such as humans and artificial materials such as cell culture fluids.
The reaction step of the present invention consists in adding the composition of the present invention to a sample, or adding the precursor of this composition to this sample. The addition step may consist of any of the methods of administration as described above.
Where possible, the activity of neuraminidase after administration of this composition can be observed by any method, including direct or indirect methods of diagnosing neuraminidase activity. Both quantitative, qualitative or semi-quantitative methods of diagnosing neuraminidase activity are available. Typically, one of the screen methods as described above applies, but any other method may also be applied, such as observing the physiological properties of living organisms.
Organisms containing neuraminidase include bacteria (cholera bacteria, Welch bacteria, pneumonia streptococci and Athrobacter sialophilus) and viruses (especially orthomyxoviruses such as influenza viruses A and B or Paramyxoviruses, parainfluenza viruses, mumps virus, Newcastle disease virus, poultry fest and Sendai virus). It is included in the object of the present invention to inhibit neuraminidase activity obtained from or found in any of these organisms. Virology of influenza viruses is described in Chapter 24 of "Fundamental Virology" (Raven Press, New York, 1986). The compounds of the present invention are useful for the treatment or prevention of such infectious diseases in animals or humans, such as, for example, ducks, rodents, or swans.
However, in the screening of compounds capable of inhibiting influenza virus, the results of the enzyme assay may not be correlated with the cell culture assay, as described in Table 1 of Chandler et al. Therefore, a plaque reduction assays must be the primary screening technique.

Metabolism of Compounds of the Invention
In vivo metabolic products of the compounds described herein are also within the scope of the present invention, unless they are novel and unambiguous with respect to the prior art. Such products can result from oxidation, reduction, hydrolysis, amidation, esterification, etc. of the administered compound, mainly due to the enzymatic process. Accordingly, the present invention includes novel and nonobvious compounds produced by a process that results in contacting a compound of the present invention with a mammal for a period of time sufficient to produce its metabolites. Such products produce radiolabeled (such as C ¹⁴ or H ³ ) compounds of the present invention and can be used in searchable dosages (such as greater than about 0.5 mg / kg) such as rats, mice, guinea pigs, monkeys or humans. Administration to animals is followed by sufficient metabolism (typically about 30 seconds to 30 hours) and identification by separating their conversion products from urine, blood or other body fluids. These products are easily separated because they are labeled (others are separated by using antibodies capable of binding epitopes surviving in the metabolite). The structure of the metabolite is determined in a conventional manner such as, for example, MS or NMR analysis. In general, the analysis of metabolites is done in the same manner as in conventional drug metabolism studies well known to those skilled in the art. Conversion products are useful in diagnostic assays for therapeutic dosages of compounds of the invention, even if they do not have neuraminidase inhibitory activity, unless otherwise found in vivo.
Another Use of the Compounds of the Invention
The compound of interest and the biologically active substance prepared by metabolism in vivo of the compound and the compound of the present invention can be used as a conjugator of an immunogen or protein. In addition, by conjugating to a protein, a component of an immunogenic composition for producing an antibody that specifically binds only to a protein having an epitope (epitope-antibody binding site) which is recognized immunologically, the compound or a product of metabolism thereof, and the like. It may be provided as. Thus, the composition of an immunogen is useful as an intermediate used to prepare antibodies for use in diagnosis, quality control or the like, or to analyze a compound of the invention or a metabolite thereof. Compounds of the present invention are useful for inducing antibodies to other non-immunogenic polypeptides as they serve as hapten sites that stimulate an immune response that cross reacts with unmodified conjugated proteins.
Important hydrolysis products include the hydrolysis products of the protected acids and bases described above. As mentioned above, amides of acids and bases consisting of immunogenic polypeptides such as albumin or keyhole limpet homocyannin are useful as immunogens. The aforementioned metabolites may have a significant degree of crossreactivity with the compounds of the present invention. Thus, the antibodies of the present invention may selectively bind unprotected compounds without binding to the protected compounds of the present invention, whereas metabolites do not bind with unprotected compounds and with protected compounds and / or metabolites May be selectively coupled, or may be coupled to any one or all three.
Immunogens of the invention contain a compound of the invention that provides an epitope suitable for binding to an immunogenic material. Within the context of the present invention, binding means a mixture of covalently or non-covalently bound substances forming an immunogenic conjugate, or a combination of the two. Immunogenic agents include adjuvants such as Freund's adjuvant, immunogenic proteins such as viruses, bacteria, yeast, animal and animal polypeptides, in particular keyhole limpet homocyanin, cerum albumin, bobbin tyroglobulin or soybean trypsin inhibitors, and It contains immunogenic polysaccharides. Compounds with appropriate epitope structures are covalently conjugated to an immunogenic polypeptide or polysaccharide using crosslinking reagents of multiple functional groups (generally two functional groups). Methods of making hapten immunogens are conventional and any method of conjugating previously used hapten to an immunogenic polypeptide or the like may be appropriately employed. However, the possibility of producing antibodies specific to the epitope in question may be considered, as opposed to functional groups and immunogenic substances possessed by precursors or hydrolysis products and useful for crosslinking.
In general, polypeptides are conjugated at positions remote from the recognized epitopes present in the compounds of the invention. Conjugates were prepared by conventional methods. For example, cross-linking reagents such as N-hydroxysuccinimide, succinic anhydride, alkN = C = Nalk and the like are useful for preparing the conjugate of the present invention. The conjugate constitutes a compound of the present invention that is attached to the immunogenic material by a linkage or a linking group having 1 to 100, preferably 1 to 25, more preferably 1 to 10 carbon atoms. The conjugate is distinguished from the starting materials and by-products by chromatography or the like and is sterile filtered and stored in the vial.
The compound of the present invention crosslinks through any one or more of, for example, a hydroxyl group of W6, a carboxyl group of E1, a carbon atom of W6, E1, G1, or T1 (substituted hydrogen) and an amine group of G1. . Included in such compounds are the amides of the polypeptides provided in the aforementioned R6c or R6b groups.
Animals are generally immune to antibodies which are immunogenic conjugates or derivatives thereof and immune serum or cells produced by traditional methods.
Compounds of the invention are useful for maintaining the structural integrity of glycoproteins in recombinant cell culture. That is, the compound of the present invention may be added to the fermentation in which the glycoproteins necessary for recovery are prepared in order to prevent the destruction of the glycoproteins catalyzed by the neuraminidase. This is of great value for the recombinant synthesis of proteins in heterologous host cells which disadvantageously reduces the carbohydrate portion of the protein being synthesized.
The compound of the present invention has a plurality of functional groups. Thus they can act as monomers in polymer synthesis. Polymers synthesized from the compounds of the present invention, by way of example or without limitation, include polyamides and polyesters.
The compounds of the present invention are used as monomers that are unique and facilitate access to polymers with unknown functional groups. The compounds of the present invention are useful in single polymers, and are also useful as monomers of monomers that do not fall within the scope of the present invention. Monomeric polymers of the compounds of the invention may be used in the preparation of molecular sieves (polyamides), textiles, fibers, films, articles in which functional groups E1 of acids are esterified by hydroxyl groups W6, and the like, in the preparation of cation exchangers (polyesters or poly Amide). For example, purification is possible by binding G1, a basic functional group of a polyester, to an acidic functional group found in a polypeptide. Polyamides are prepared by the crosslinking of E1 and G1, where W6 and the portion adjacent to W6 in the ring have nucleophilic or electrophilic affinity. Methods for preparing such polymers from the compounds of the present invention are well known.
The compounds of the present invention are also useful as surfactants. Especially when W6 does not have a nucleophilic substituent, for example an alkyl or alkoxy group, the compound has the property as a bi-functional surfactant. Thus, the compound has surface activity, surface coating, emulsion deformation, fluidity deformation and surface wetting properties.
Because of having the specified geometry and polar and nonpolar moieties, the compounds of the present invention are used as phase transfer reagents. By way of example or without limitation, the compounds of the present invention are useful as phase transfer catalysts and liquid / liquid ion extraction (LIX).
The compounds of the present invention may optionally have asymmetric carbons among the W6, E1, G1, and T1 groups. Accordingly, the compounds of the present invention are used as chiral auxiliaries for the synthesis or separation of optically active substances. For example, the racemate of carboxylic acid
1) forming a diastereomeric ester or amide with a compound of the invention wherein W6 is an asymmetric hydroxyalkane or aminoalkane,
2) separating diastereomers,
3) can be separated into each component enantiomer by the step of hydrolyzing the ester. Alcohol racemates can also be separated by the formation of esters with the acidic group E1. Furthermore, this method can be used for the separation of the compounds of the present invention, provided that the starting material is not a racemate but an optically active material.
The compounds of the present invention are used for the use of linkers or spacers in affinity absorption substrates, process control non-flowing enzymes or immunoassays. The compound contains a plurality of functional groups therein suitable for bonding with substances requiring crosslinking. For example, it is common to combine hormones, peptides, antibodies, medicines and similar affinity reagents with insoluble substrates. This insoluble substrate can be employed for the purpose of absorbing affinity reagents as binding partners from pharmaceuticals, diagnostic samples and mixtures containing impurities by known methods. Similarly, non-flowing enzymes can be used for the purpose of performing catalytic conversion while recovering themselves easily. In the preparation of diagnostic reagents, dual functional compounds are commonly used for linking analytes to detectable groups.
The plural functional groups possessed by the compounds of the present invention are suitable for cross-linking applications. For example, the carboxylic or phosphonic acid functional groups of El are suitable for forming amides with alcohols or esters or amines. G1 substituted by OH, NHR1, SH, azido (converted to amino group before crosslinking), CN, NO2, amino, guanidino, halo and the like is also crosslinkable. Appropriate protection of the functional groups can be done to prevent polymerisation between the compounds of the invention. Generally, the carboxy or posophonic acid functional group of the compound of the present invention is bonded to the hydroxy or amino group of the first binding partner, followed by binding to another partner using a T1 or G1 group. Non-flowable steroids are obtained by, for example, ester-linking a first binding partner, such as a steroid, with a carboxylic acid of the invention and covalently linking a G1 hydroxy group with a cyanozenbromide-activated sephaarose. Chemistry for other conjugations is well known. For example, look at Maggio's "Enzyme-immunoessay" (CRC, 1988, pp 71-135) and references cited therein. As mentioned above, clinically useful compounds of the invention wherein the W1 or G1 carboxyl, hydroxyl or amino groups are protected are used orally or sustained release. In such use, the protecting group is removed by hydrolysis or oxidation in vivo to yield an unprotected carboxyl, amino or hydroxy group. Suitable esters or amides for this use are selected based on the substrate specificity of the esterases and / or carboxypeptidases found in cells in need of hydrolysis of the precursors. As the substrate specificity of the enzyme is unknown, screens for a plurality of compounds of the invention are needed until the desired substrate specificity is found. Substrate specificity is confirmed by the appearance of unprotected acid or antiviral activity. The reason for the general choice of ester or amide form among the compounds of the invention is i) not hydrolyzed or very slowly hydrolyzed in the upper gut, ii) penetrated into gut and cells, iii) cytoplasmic or systemic circulation This is because hydrolysis takes place during the process. Screen assays use cells from tissues susceptible to influenza (eg, mucosa of the bronchial lineage). Assays known in the art are useful for determining bioavailability in vivo, including intestinal lumen stability, cell penetration, hepatic liquor stability and plasma stability assays. However, esters, amides or other protected derivatives are useful as chemical intermediates even if they do not change in carboxyl, amino or hydroxy groups in vivo.
