    WO 2006/005667 PCT/EP2005/052874 1 POLYPEPTIDE PROTRACTING TAGS FIELD OF THE INVENTION 5 The present invention relates to compounds comprising a heterocyclic carboxylic acid bioisostere, methods for preparing the compounds and the medical applications of such compounds. 10 BACKGROUND OF THE INVENTION It is often desirable to maintain well-defined concentrations of a given compound in the blood stream for a long time. This would for instance be the case when an immunogen is administered and a strong immune response is desired, or when a therapeutic target has to 15 be exposed continuously to a therapeutic agent for a long time. Currently there are no universally applicable strategies to enhance the plasma half-life of any type of compound. The number of known endogenous polypeptides with interesting biological activities is growing rapidly, also as a result of the ongoing exploration of the human genome. Due to their biological activities, many of these polypeptides could in principle be used as 20 therapeutic agents. Endogenous peptides are, however, not always suitable as drug candidates because these peptides often have half-lives of few minutes due to rapid degradation by peptidases and/or due to renal filtration and excretion in the urine. The half life of polypeptides in human plasma varies strongly (from a few minutes to more than one week). Similarly, the half-life of small molecule drugs is also highly variable. The reason for 25 this strong variability of plasma half-lives of peptides, proteins, or other compounds is, however, not well understood. Serum albumin has a half-life of more than one week, and one approach to increasing the plasma half-life of peptides has been to derivatised the peptides with a chemical entity that binds to serum albumin. 30 Knudsen et al. (J. Med. Chem. 2000, 43, 1664-1669) have shown that acylated GLP-1 peptides exhibit high receptor potency and a tenfold increase of plasma half-life in pigs. Zobel et al. (Bioorg. Med. Chem. Lett. 2003, 13,1513-1515) have shown that the plasma half-life of an anticoagulant peptide in rabbits increased by 10-50 fold on derivatisation of the amino terminus with phosphate ester based small molecules binding to serum albumin.

A polyradical according to this definition may be used to covalently link two or more (mono-)radicals together. The term "small molecule drug" means a therapeutic agent with a molecular weight < 1500 g/mol.
    WO 2006/005667 PCT/EP2005/052874 5 The term "therapeutic agent" means a peptide, protein, small molecule drug, or any other type of compound, able to elicit a biological response. The term "plasma half-life" means the time required for the concentration of a given compound present in the plasma of a living mammal, such as a human, to decrease to one 5 half of its original concentration. The term "analog" refers to a polypeptide in which less than 30% of the amino acids of the original polypeptide have been removed or replaced by other amino acids (including stereoisomeric, unnatural or chemically modified amino acids) or have been chemically modified, for instance by acylation or alkylation of the side chain. The term "analog" also 10 refers to polypeptides in which the N-terminal amino group has been removed, alkylated with lower alkyl, or acylated with lower alkanoic, arylalkanoic, heteroarylalkanoic, or benzoic acids. The term "analog" also includes polypeptides in which the C-terminal carboxyl group has been removed or converted to an amide by condensation with ammonia, lower alkyl amines, lower dialkyl amines, aziridine, azetidine, pyrrolidine, piperidine, or azepine. The 15 term "analog" also includes polypeptides in which the disulfide functionalities between two or more cystein groups have been reduced or the connectivity between two or more cystein groups has been modified. The term "derivative" as used herein in relation to a peptide means a chemically modified peptide or an analogue thereof, wherein at least one substituent is not present in the unmodified 20 peptide or an analogue thereof, i.e. a peptide which has been covalently modified. Typical modifications are amides, carbohydrates, alkyl groups, acyl groups, esters and the like. An example of a derivative of GLP-1 (7-37) is Arg34Lysm(N'-(y-Glu(N'-hexadecanoyl)))-GLP-1 (7-37). The term "unnatural amino acid" refers to any compound comprising at least one primary or secondary amino group and at least one carboxyl group, without being L-alanine, L 25 arginine, L-asparagine, L-aspartic acid, L-cysteine, L-glutamine, L-glutamic acid, L-glycine, L-histidine, L-isoleucine, L-leucine, L-lysine, L-methionine, L-phenylalanine, proline, L serine, L-threonine, L-tryptophan, L-tyrosine, or L-valine. The term "GLP-1 (7-37)" refers to a peptide with the amino acid sequence HAEGTFTSDVSSYLEGQAAKEFIAWLVKGRG (SEQ ID No. 1). 30 The term "GLP-1 peptide" as used herein means GLP-1 (7-37), a GLP-1 analog, a GLP-1 derivative or a derivative of a GLP-1 analog. In one embodiment the GLP-1 peptide is an insulinotropic agent. The term "exendin-4(1-39)" refers to a peptide with the amino acid sequence HGEGTFTSDLSKQMEEEAVRLFIEWLKNGGPSSGAPPPS (SEQ ID No. 2).
    WO 2006/005667 PCT/EP2005/052874 6 The term "insulinotropic agent" as used herein means a compound which is an agonist of the human GLP-1 receptor, i.e. a compound which stimulates the formation of cAMP in a suitable medium containing the human GLP-1 receptor. The potency of an insulinotropic agent is determined by calculating the ECso value from the dose-response curve as 5 described below. Baby hamster kidney (BHK) cells expressing the cloned human GLP-1 receptor (BHK-467-12A) were grown in DMEM media with the addition of 100 IU/mL penicillin, 100 pL/mL streptomycin, 10% fetal calf serum and 1 mg/mL Geneticin G-418 (Life Technologies). Plasma membranes were prepared by homogenisation in buffer (10 mM Tris-HCI, 30 mM NaCI and 1 mM 10 dithiothreitol, pH 7.4, containing, in addition, 5 mg/L leupeptin (Sigma, St. Louis, MO, USA), 5 mg/L pepstatin (Sigma), 100 mg/L bacitracin (Sigma), and 16 mg/L aprotinin (Calbiochem Novabiochem, La Jolla, CA). The homogenate was centrifuged on top of a layer of 41 w/v% sucrose. The white band between the two layers was diluted in buffer and centrifuged. Plasma membranes were stored at -80 0 C until used. 15 The functional receptor assay was carried out by measuring cAMP as a response to stimulation by the insulinotropic agent. Incubation were carried out in 96-well microtiter plates in a total volume of 140 pIL and with the following final concentrations: 50 mM Tris-HCI, 1 mM EGTA, 1.5 mM MgSO 4 , 1.7 mM ATP, 20 mM GTP, 2 mM 3-isobutyl-1 -methylxanthine (IBMX), 0.01 % Tween-20, pH 7.4. Compounds to be tested for agonist activity were dissolved and diluted in 20 buffer. GTP was freshly prepared for each experiment: 2.5 pg of membrane was added to each well and the mixture was incubated for 90 min at room temperature in the dark with shaking. The reaction was stopped by the addition of 25 pL of 0.5 M HCI. Formed cAMP was measured by a scintillation proximity assay (RPA 542, Amersham, UK). Dose-response curves were plotted for the individual compounds and ECho values calculated using GraphPad Prism software. 25 The term "DPP-IV protected" as used herein referring to a polypeptide means a polypeptide which has been chemically modified in order to render said compound resistant to the plasma peptidase dipeptidyl aminopeptidase-4 (DPP-IV). The DPP-IV enzyme in plasma is known to be involved in the degradation of several peptide hormones, e.g. GLP-1, GLP-2, Exendin-4 etc. Thus, a considerable effort is being made to develop analogues and derivatives of the 30 polypeptides susceptible to DPP-IV mediated hydrolysis in order to reduce the rate of degradation by DPP-IV. Resistance of a peptide to degradation by dipeptidyl aminopeptidase IV is determined by the following degradation assay : WO 2006/005667 PCT/EP2005/052874 7 Aliquots of the peptide (5 nmol) are incubated at 37 2C with 1 pL of purified dipeptidyl aminopeptidase IV corresponding to an enzymatic activity of 5 mU for 10-180 minutes in 100 ptL of 0.1 M triethylamine-HCI buffer, pH 7.4. Enzymatic reactions are terminated by the addition of 5 piL of 10% trifluoroacetic acid, and the peptide degradation products are 5 separated and quantified using HPLC analysis. One method for performing this analysis is: The mixtures are applied onto a Vydac C18 widepore (30 nm pores, 5 pm particles) 250 x 4.6 mm column and eluted at a flow rate of 1 ml/min with linear stepwise gradients of acetonitrile in 0.1% trifluoroacetic acid (0% acetonitrile for 3 min, 0-24% acetonitrile for 17 min, 24-48% acetonitrile for 1 min) according to Siegel et al., Regul. Pept. 1999;79:93-102 10 and Mentlein et al. Eur. J. Biochem. 1993;214:829-35. Peptides and their degradation products may be monitored by their absorbance at 220 nm (peptide bonds) or 280 nm (aromatic amino acids), and are quantified by integration of their peak areas related to those of standards. The rate of hydrolysis of a peptide by dipeptidyl aminopeptidase IV is estimated at incubation times which result in less than 10% of the peptide being hydrolysed. 15 The term "factor VII" refers to the human factor VII of the blood clotting cascade. The term "bioisostere" refers to a molecular fragment capable of mimicking the biological properties of another molecular fragment. Typical bioisosteres of carboxylic acids include tetrazoles, phenols, N-acylsulfonamides, or other compounds with an acidic NH- or OH 20 group. The term "halogen" means F, CI, Br or I.

    5 , and 30 t is 1-40, and WO 2006/005667 PCT/EP2005/052874 10 the term 'molecule' refers to a compound comprising an amino group or a mercapto group, to which the group A or Q may be covalently linked. 5 Tetrazoles are slightly more lipophilic than carboxylic acids, but are resistant to many of the metabolic degradation pathways which befall carboxylic acids. Because tetrazoles cannot act as acylating reagents no protective group is required when acylating a protein with an ro (tetrazol-5-yl)carboxylic acid. We have found that the derivatization of polypeptides with tetrazole-containing molecular 10 entities is readily performed, and that, surprisingly, the resulting protein-tetrazole conjugates show highly improved biological and pharmacological properties. As illustrated by the examples below, between the tetrazole and the molecule of which a prolonged half-life in plasma is required there may be an optional spacer, i.e. a divalent or 15 polyvalent molecular fragment able to covalently connect one or several tetrazoles to the molecule. This divalent or polyvalent molecular fragment may also have an influence on the biological properties of the conjugate compound-tetrazole(s), and structural modifications of this spacer may be used to adjust and improve the properties of the conjugate. This spacer may be a combination of one or several different structural elements selected from but not 20 limited to alkylene chains, partially or fully fluorinated alkylene chains, arylenes, heteroarylenes, oligo(ethylene glycol), amide bonds, lysine, short peptides, short oligoamides, and other, similar fragments. For connecting the tetrazole-bearing spacer to a compound of interest, such as a 25 therapeutically relevant protein or peptide, various different strategies may be envisioned. Many polypeptides contain amino groups (e.g. the N-terminal amino group or lysine-side chain amino groups), which can be acylated by a suitable acylating reagent, such as a carboxylic acid in the presence of a coupling reagent, a carboxylic acid O hydroxysuccinimidyl ester, hydroxybenzotriazole esters, carboxylic acid anhydrides, 30 carboxylic acid halides, carboxylic acid azides, nitrophenyl esters, mixed carboxylic carbonic anhydrides, mixed carboxylic sulfonic anhydrides, imidazolides, and the like. Alternatively, amino-group bearing polypeptides may be derivatized by conversion into a carbamate by treatment with an alkyl haloformiate, an O-succinimidylcarbonate, an alkyl azidoformiate, or a related reagent. Alternatively, amino-group bearing polypeptides may be derivatized by WO 2006/005667 PCT/EP2005/052874 11 conversion into a urea by treatment with an isocyanate, a carbamoyl halide, a nitrophenyl carbamate, or a related reagent. Alternatively, amino-group bearing polypeptides may be derivatized by conversion into a sulfonamide by treatment with a sulfonyl halide or sulfonyl imidazolide. 5 All these derivatization reactions can be conducted without the need of any protective group for the tetrazole ring, and are therefore particularly well suited for the derivatization of sensitive polypeptides.

    0 0 10 0 0 WO 2006/005667 PCT/EP2005/052874 12 Many polypeptides contain thiol groups, which can be alkylated by treatment with a suitable alkylating reagent, such as an alkyl halide, an alkyl sulfonate, an N-alkylmaleimide, an acrylamide, or a related alkylating reagent, to covalently bind the tetrazole-bearing fragment 5 to the polypeptide. Alternatively, thiol groups may also be arylated by treatment with a suitable arylating reagent, such as an aryl halide, an aryl iodonium salt, an aryldiazonium salt or a similar reagent. Polypeptides with N-terminal serine or a related functional group (a 1,2-diol, a 2 aminoethanol) can be oxidized by treatment with periodate to an aldehyde. This aldehyde 10 reacts with O-alkylhydroxylamines to yield oximes, and may therefore be used to attach an O-alkylhydroxylamine-containing tetrazole to the polypeptide. The aldehyde formed by oxidation of N-terminal serine also reacts with 2-aminoethylthiols (HS-C-C-NH) to yield thiazolidines, or with hydrazines to yield hydrazones, and these reactions may also be used for the attachment of a tetrazole-bearing fragment to a polypeptide. Aldehydes also react 15 with C,H-acidic compounds such as 1,3-diketones, 3-oxobutyramides, malonodinitriles, barbituric acid derivatives, malonic acid derivatives, and the like to yield alcohols (aldol addition) or alkenes (Knoevenagel condensation). These reactions may also be used to attach tetrazoles to polypeptides. Enzymes enable the selective derivatization of polypeptides. Thus, carboxypeptidases can 20 be used to form amides from amines and the C-terminal carboxylic acid group of a polypeptide. Transglutaminases may be used to form new amides from amines and the side chain of glutamine. If these enzymatic reactions are performed with a tetrazole-bearing amine, compounds as claimed in this invention will result. Alternatively, these enzymatic reactions may also be conducted with an amine which contains a functional group which 25 enables a selective covalent attachment of a tetrazole-bearing fragment in a second operation. Such functional groups may be aldehydes, ketones, hydroxylamines, alkoxylamines, hydrazines, thiols, azides, 2-aminoethylthiols, 3-aminopropylthiols, 2 hydroxyethylthiols, 3-hydroxypropylthiols, alkynes, alkenes, nitriles, C,H-acidic compounds, or other functional groups which enable the selective covalent attachment of a tetrazole 30 bearing fragment. Treatment of an amine containing one or several of these functional groups will yield a polypeptide, which can be selectively derivatized. A methodology for the production of proteins containing unnatural amino acids by fermentation has recently been described (for instance L. Alfonta et al., J. Am. Chem. Soc. 2003, 125, 14662-14663; Z. Zhang et al., Biochemistry, 2003, 42, 6735-6746). This WO 2006/005667 PCT/EP2005/052874 13 methodology may also be used to prepare proteins with tetrazole-containing amino acids directly or proteins with an unnatural amino acid which enables facile chemical derivatization. These could, for instance, be amino acids containing a formyl group, a keto group, an azido group, a mercapto group, an alkoxylamino group, a hydrazino group, an 5 alkyne, an alkene, an aryl iodide, or an aryl bromide. The resulting protein, containing this unnatural amino acid, may then be converted into a tetrazole-containing protein by covalent binding of a suitable tetrazole derivative to the side chain of the unnatural amino acid.

The therapeutic polypeptides can be produced by classical peptide synthesis, e.g. solid phase peptide synthesis using t-Boc or F-Moc chemistry or other well established techniques., 20 see e.g. Green and Wuts, "Protecting Groups in Organic Synthesis", Jogn Wiley & Sons, 1999. The therapeutic polypeptides can also be produced by a method which comprises culturing a host cell containing a DNA sequence encoding the polypeptide and capable of expressing the polypeptide in a suitable nutrient medium under conditions permitting the expression of the peptide, after which the resulting peptide is recovered from the culture. 25 The medium used to culture the cells may be any conventional medium suitable for growing the host cells, such as minimal or complex media containing appropriate supplements. Suitable media are available from commercial suppliers or may be prepared according to published recipes (e.g. in catalogues of the American Type Culture Collection). The peptide produced by the cells may then be recovered from the culture medium by conventional 30 procedures including separating the host cells from the medium by centrifugation or filtration. For extracellular products the proteinaceous components of the supernatant are isolated by filtration, column chromatography or precipitation, e.g. microfiltation, ultrafiltration, isoelectric precipitation, WO 2006/005667 PCT/EP2005/052874 42 purification by a variety of chromatographic procedures, e.g. ion exchange chromatography, hydrophobic interaction chromatography, gel filtration chromatography, affinity chromatography, or the like, dependent on the type of polypeptide in question. For intracellular or periplasmic products the cells isolated from the culture medium are disintegrated or permeabilised and 5 extracted to recover the product polypeptide or precursor thereof. The DNA sequence encoding the therapeutic polypeptide may suitably be of genomic or cDNA origin, for instance obtained by preparing a genomic or cDNA library and screening for DNA sequences coding for all or part of the peptide by hybridisation using synthetic oligonucleotide probes in accordance with standard techniques (see, for example, Sambrook, J, 10 Fritsch, EF and Maniatis, T, Molecular Cloning: A Laboratory Manual, Cold Spring Harbor Laboratory Press, New York, 1989). The DNA sequence encoding the polypeptide may also be prepared synthetically by established standard methods, e.g. the phosphoamidite method described by Beaucage and Caruthers, Tetrahedron Letters 22 (1981), 1859 - 1869, or the method described by Matthes et al., EMBO Journal 3 (1984), 801 - 805. The DNA sequence 15 may also be prepared by polymerase chain reaction using specific primers, for instance as described in US 4,683,202 or Saiki et al., Science 239 (1988), 487 - 491. The DNA sequence may be inserted into any vector which may conveniently be subjected to recombinant DNA procedures, and the choice of vector will often depend on the host cell into which it is to be introduced. Thus, the vector may be an autonomously replicating 20 vector, i.e. a vector which exists as an extrachromosomal entity, the replication of which is independent of chromosomal replication, e.g. a plasmid. Alternatively, the vector may be one which, when introduced into a host cell, is integrated into the host cell genome and replicated together with the chromosome(s) into which it has been integrated. The vector is preferably an expression vector in which the DNA sequence encoding the 25 polypeptide is operably linked to additional segments required for transcription of the DNA, such as a promoter. The promoter may be any DNA sequence which shows transcriptional activity in the host cell of choice and may be derived from genes encoding proteins either homologous or heterologous to the host cell. Examples of suitable promoters for directing the transcription of the DNA encoding the peptide of the invention in a variety of host cells are well known in the art, cf. 30 for instance Sambrook et al, supra. The DNA sequence encoding the polypeptide may also, if necessary, be operably connected to a suitable terminator, polyadenylation signals, transcriptional enhancer sequences, and translational enhancer sequences. The recombinant vector of the invention may further comprise a DNA sequence enabling the vector to replicate in the host cell in question.
    WO 2006/005667 PCT/EP2005/052874 43 The vector may also comprise a selectable marker, e.g. a gene the product of which complements a defect in the host cell or one which confers resistance to a drug, e.g. ampicillin, kanamycin, tetracyclin, chloramphenicol, neomycin, hygromycin or methotrexate. For large scale manufacture the selectable marker preferably is not antibiotic resistance, e.g. antibiotic 5 resistance genes in the vector are preferably excised when the vector is used for large scale manufacture. Methods for eliminating antibiotic resistance genes from vectors are known in the art, see e.g. US 6,358,705 which is incorporated herein by reference. To direct a parent peptide of the present invention into the secretory pathway of the host cells, a secretory signal sequence (also known as a leader sequence, prepro sequence or 10 pre sequence) may be provided in the recombinant vector. The secretory signal sequence is joined to the DNA sequence encoding the peptide in the correct reading frame. Secretory signal sequences are commonly positioned 5' to the DNA sequence encoding the peptide. The secretory signal sequence may be that normally associated with the peptide or may be from a gene encoding another secreted protein. 15 The procedures used to ligate the DNA sequences coding for the present peptide, the promoter and optionally the terminator and/or secretory signal sequence, respectively, and to insert them into suitable vectors containing the information necessary for replication, are well known to persons skilled in the art (cf., for instance, Sambrook et al.., supra). The host cell into which the DNA sequence or the recombinant vector is introduced 20 may be any cell which is capable of producing the present peptide and includes bacteria, yeast, Yungi and higher eukaryotic cells. Examples of suitable host cells weliknown and used in the art are, without limitation, E. coli, Saccharomyces cerevisiae, or mammalian BHK or CHO cell lines.

By "dried form" is intended the liquid pharmaceutical composition or formulation is dried either by freeze drying (i.e., lyophilization; see, for example, Williams and Polli (1984) J. Parenteral Sci. Technol. 38:48-59), spray drying (see 5 Masters (1991) in Spray-Drying Handbook (5th ed; Longman Scientific and Technical, Essez, U.K.), pp. 491-676; Broadhead et al. (1992) Drug Devel. Ind. Pharm. 18:1169-1206; and Mumenthaler et al. (1994) Pharm. Res. 11:12-20), or air drying (Carpenter and Crowe (1988) Cryobiology 25:459-470; and Roser (1991) Biopharm. 4:47-53). Aggregate formation by a polypeptide during storage of a liquid pharmaceutical composition can adversely affect 10 biological activity of that polypeptide, resulting in loss of therapeutic efficacy of the pharmaceutical composition. Furthermore, aggregate formation may cause other problems such as blockage of tubing, membranes, or pumps when the polypeptide-containing pharmaceutical composition is administered using an infusion system. The pharmaceutical compositions of the invention may further comprise an amount 15 of an amino acid base sufficient to decrease aggregate formation by the polypeptide during storage of the composition. By "amino acid base" is intended an amino acid or a combination of amino acids, where any given amino acid is present either in its free base form or in its salt form. Where a combination of amino acids is used, all of the amino acids may be present in their free base forms, all may be present in their salt forms, or some may 20 be present in their free base forms while others are present in their salt forms. In one efnbodiment, amino acids to use in preparing the compositions of the invention are those carrying a charged side chain, such as arginine, lysine, aspartic acid, and glutamic acid. Any stereoisomer (i.e. R or S-isomers - or L, D or DL-isomer) of a particular amino acid (e.g. alanine, methionine methionine, histidine, imidazole, arginine, lysine, isoleucine, 25 aspartic acid, tryptophan, threonine and mixtures thereof) or combinations of these stereoisomers, may be present in the pharmaceutical compositions of the invention so long as the particular amino acid is present either in its free base form or its salt form. In one embodiment the L-stereoisomer is used, which denotes the most abundant form of aminoacids. The L-form may be an R or an S isomer dependent on the specific aminoacid. 30 Compositions of the invention may also be formulated with analogues of these amino acids. By "amino acid analogue" is intended a derivative of the naturally occurring amino acid that brings about the desired effect of decreasing aggregate formation by the polypeptide during storage of the liquid pharmaceutical compositions of the invention. Suitable arginine analogues include, for example, aminoguanidine, ornithine and N-monoethyl L-arginine, WO 2006/005667 PCT/EP2005/052874 48 suitable methionine analogues include S-ethyl homocysteine and S-butyl homocysteine and suitable cystein analogues include S-methyl-L cystein. As with the other amino acids, the amino acid analogues are incorporated into the compositions in either their free base form or their salt form. In a further embodiment of the invention the amino acids or amino acid 5 analogues are used in a concentration, which is sufficient to prevent or delay aggregation of the protein. In a further embodiment of the invention methionine (or other sulphur containing amino acids or amino acid analogous) may be added to inhibit oxidation of methionine residues to methionine sulfoxide when the polypeptide acting as the therapeutic agent is a 10 polypeptide comprising at least one methionine residue susceptible to such oxidation. By "inhibit" is intended minimal accumulation of methionine oxidized species over time. Inhibiting methionine oxidation results in greater retention of the polypeptide in its proper molecular form. Any stereoisomer of methionine (L, D, or DL isomer) or combinations thereof can be used. The amount to be added should be an amount sufficient to inhibit 15 oxidation of the methionine residues such that the amount of methionine sulfoxide is acceptable to regulatory agencies. Typically, this means that the composition contains no more than about 10% to about 30% methionine sulfoxide. Generally, this can be achieved by adding methionine such that the ratio of methionine added to methionine residues ranges from about 1:1 to about 1000:1, such as 10:1 to about 100:1. 20 In a further embodiment of the invention the formulation further comprises a stabiliser selected from the group of high molecular weight polymers or low molecular compounds. In a further embodiment of the invention the stabilizer is selected from polyethylene glycol (e.g. PEG 3350), polyvinylalcohol (PVA), polyvinylpyrrolidone, carboxy /hydroxycellulose or derivates thereof (e.g. HPC, HPC-SL, HPC-L and HPMC), 25 cyclodextrins, sulphur-containing substances as monothioglycerol, thioglycolic acid and 2 methylthioethanol, and different salts (e.g. sodium chloride). Each one of these specific stabilizers constitutes an alternative embodiment of the invention. The pharmaceutical compositions may also comprise additional stabilizing agents, which further enhance stability of a therapeutically active polypeptide therein. 30 Stabilizing agents of particular interest to the present invention include, but are not limited to, methionine and EDTA, which protect the polypeptide against methionine oxidation, and a nonionic surfactant, which protects the polypeptide against aggregation associated with freeze-thawing or mechanical shearing.

Tetronic's), which are tetrafunctional block copolymers derived from sequential addition of propylene oxide and ethylene oxide to 5 ethylenediamine, or the surfactant may be selected from the group of imidazoline derivatives, or mixtures thereof. Each one of these specific surfactants constitutes an alternative embodiment of the invention. The use of a surfactant in pharmaceutical compositions is well-known to the skilled person.

Such additional ingredients may include wetting agents, emulsifiers, antioxidants, bulking agents, tonicity modifiers, chelating agents, metal 15 ions, oleaginous vehicles, proteins (e.g., human serum albumin, gelatin or proteins) and a zwitterion (e.g., an amino acid such as betaine, taurine, arginine, glycine, lysine and histidine).

General reference is made to Handbook of Pharmaceutical Controlled Release (Wise, D.L., ed. Marcel Dekker, New York, 2000) and Drug and the Pharmaceutical Sciences vol. 99: Protein Formulation and Delivery (MacNally, E.J., ed. Marcel Dekker, New York, 2000). 10 Parenteral administration may be performed by subcutaneous, intramuscular, intraperitoneal or intravenous injection by means of a syringe, optionally a pen-like syringe. Alternatively, parenteral administration can be performed by means of an infusion pump. A further option is a composition which may be a solution or suspension for the administration of the compound according to the present invention in the form of a nasal or pulmonal 15 spray. As a still further option, the pharmaceutical compositions containing the compound of the invention can also be adapted to transdermal administration, e.g. by needle-free injection or from a patch, optionally an iontophoretic patch, or transmucosal, e.g. buccal, administration. The term "stabilized formulation" refers to a formulation with increased 20 physical stability, increased chemical stability or increased physical and chemical stability. The term "physical stability" of the protein formulation as used herein refers to the tendency of the protein to form biologically inactive and/or insoluble aggregates of the protein as a result of exposure of the protein to thermo-mechanical 25 stresses and/or interaction with interfaces and surfaces that are destabilizing, such as hydrophobic surfaces and interfaces. Physical stability of the aqueous protein formulations is evaluated by means of visual inspection and/or turbidity measurements after exposing the formulation filled in suitable containers (e.g. cartridges or vials) to mechanical/physical stress (e.g. agitation) at different temperatures for various time periods. Visual inspection of 30 the formulations is performed in a sharp focused light with a dark background. The turbidity of the formulation is characterized by a visual score ranking the degree of turbidity for instance on a scale from 0 to 3 (a formulation showing no turbidity corresponds to a visual score 0, and a formulation showing visual turbidity in daylight corresponds to visual score 3). A formulation is classified physical unstable with respect to protein aggregation, when it WO 2006/005667 PCT/EP2005/052874 53 shows visual turbidity in daylight. Alternatively, the turbidity of the formulation can be evaluated by simple turbidity measurements well-known to the skilled person. Physical stability of the aqueous protein formulations can also be evaluated by using a spectroscopic agent or probe of the conformational status of the protein. The probe is preferably a small 5 molecule that preferentially binds to a non-native conformer of the protein. One example of a small molecular spectroscopic probe of protein structure is Thioflavin T. Thioflavin T is a fluorescent dye that has been widely used for the detection of amyloid fibrils. In the presence of fibrils, and perhaps other protein configurations as well, Thioflavin T gives rise to a new excitation maximum at about 450 nm and enhanced emission at about 482 nm 10 when bound to a fibril protein form. Unbound Thioflavin T is essentially non-fluorescent at the wavelengths. Other small molecules can be used as probes of the changes in protein structure from native to non-native states. For instance the "hydrophobic patch" probes that bind preferentially to exposed hydrophobic patches of a protein. The hydrophobic patches are 15 generally buried within the tertiary structure of a protein in its native state, but become exposed as a protein begins to unfold or denature. Examples of these small molecular, spectroscopic probes are aromatic, hydrophobic dyes, such as antrhacene, acridine, phenanthroline or the like. Other spectroscopic probes are metal-amino acid complexes, such as cobalt metal complexes of hydrophobic amino acids, such as phenylalanine, 20 leucine, isoleucine, methionine, and valine, or the like. The term "chemical stability" of the protein formulation as used herein refers to chemical covalent changes in the protein structure leading to formation of chemical degradation products with potential less biological potency and/or potential increased 25 immunogenic properties compared to the native protein structure. Various chemical degradation products can be formed depending on the type and nature of the native protein and the environment to which the protein is exposed. Elimination of chemical degradation can most probably not be completely avoided and increasing amounts of chemical degradation products is often seen during storage and use of the protein formulation as 30 well-known by the person skilled in the art. Most proteins are prone to deamidation, a process in which the side chain amide group in glutaminyl or asparaginyl residues is hydrolysed to form a free carboxylic acid. Other degradations pathways involves formation of high molecular weight transformation products where two or more protein molecules are covalently bound to each other through transamidation and/or disulfide interactions leading WO 2006/005667 PCT/EP2005/052874 54 to formation of covalently bound dimer, oligomer and polymer degradation products (Stability of Protein Pharmaceuticals, Ahern. T.J. & Manning M.C., Plenum Press, New York 1992). Oxidation (of for instance methionine residues) can be mentioned as another variant of chemical degradation. The chemical stability of the protein formulation can be evaluated 5 by measuring the amount of the chemical degradation products at various time-points after exposure to different environmental conditions (the formation of degradation products can often be accelerated by for instance increasing temperature). The amount of each individual degradation product is often determined by separation of the degradation products depending on molecule size and/or charge using various chromatography techniques (e.g. 10 SEC-HPLC and/or RP-HPLC). Hence, as outlined above, a "stabilized formulation" refers to a formulation with increased physical stability, increased chemical stability or increased physical and chemical stability. In general, a formulation must be stable during use and storage (in compliance 15 with recommended use and storage conditions) until the expiration date is reached. In one embodiment of the invention the pharmaceutical formulation comprising the compound according to the present invention is stable for more than 6 weeks of usage and for more than 3 years of storage. 20 In another embodiment of the invention the pharmaceutical formulation comprising the compound according to the present invention is stable for more than 4 weeks of usage and for more than 3 years of storage. In a further embodiment of the invention the pharmaceutical formulation comprising the compound according to the present invention is stable for more than 4 weeks of usage 25 and for more than two years of storage. In an even further embodiment of the invention the pharmaceutical formulation comprising the compound is stable for more than 2 weeks of usage and for more than two years of storage. 30 In another aspect the present invention relates to the use of a compound according to the invention for the preparation of a medicament.

The reaction mixture was stirred for 1 h and purified by ion exchange chromatography. Purification of monoacylated hGH in position 140 or 145. 15 The crude reaction mixture was diluted five times in 50 mM Tris pH 8.5 and applied to a Mono Q column. For purification of 6 ml crude reaction mixture a 10 ml 10/10 Mono Q column from Amersham Pharmcia was used. A 1000 CV gradient was used to separate the native, monoacylated in position 30/45/70, monoacylated in position 140/145, diacylated and triacylated hGH. Shortly after elution of the triacylated hGH, a steep gradient was used 20 to elute dimeric hGH. As eluting buffer 50 mM Tris, 2 M NaCI, pH 8.5 was used. The purification was performed at 4 OC. After elution, fractions containing monoacylated hGH (peak 2) was pooled and subsequently ultrafiltrated using a Amicon with a YM10 filter. The washing buffer was 50 25 mM Ammoniumcarbonate pH 8.0. After ultrafiltration, the acylated protein was lyophillised. Chromatograms depicting A280 nm and A254 nm both exhibited five distinct peaks which were characterised by peptide mapping: Peak 1 contains native hGH WO 2006/005667 PCT/EP2005/052874 74 Peak 2 contains monoacylated hGH in position 38 or 45 or 70.
