专利说明:

PULMONARY DELIVERY OF ACTIVE AGENTS}
[2] Traditional active agent delivery means are often severely limited by biological, chemical and physical barriers. Typically, these barriers are imposed by the environment through which delivery occurs, the environment of the target to be delivered, or the target itself. Biological or chemical active agents are vulnerable to such barriers.
[3] For example, when delivering a biological or chemical active agent or therapeutic agent to an animal, a barrier is imposed by the body. Examples of physical barriers are skin and various types of visceral membranes that must pass through before reaching the target. Chemical barriers include, but are not limited to, pH variations, lipid bilayers and degrading enzymes.
[4] Pulmonary delivery of many biologically active agents to the circulatory system can be selected as the route of administration to animals because delivery to the blood is much faster than other delivery routes. In addition, delivery to the lung itself may be required, for example, to treat diseases of the pulmonary system. However, lung delivery may not be practical because of the physical barriers such as lipid bilayers and membranes, which each particular biologically active agent cannot pass through but must pass before the agent can reach the circulation. Lung delivery may also be achieved in other cases, but may not be sufficiently effective for practical purposes.
[5] There is a current need for a simple and inexpensive lung delivery system that is easily manufactured and capable of delivering a wide range of active agents in an effective manner.
[1] The present invention relates to the delivery of an active agent through the lungs. Acylated or sulfonated amino acids are used as carriers for lung delivery of the active agent to the target.

It is useful for delivery or administration to any animal, including but not limited to cats, primates and especially humans.

[44] Acylated amino acids can be prepared by reacting one amino acid, two or more amino acids, or amino acid esters with an amine modifier that reacts with the free amino groups present in the amino acid to produce an amide.
[45] Examples of suitable acylating agents for preparing acylated amino acids include, but are not limited to, acid chloride acylating agents having the formula:
[46]
[47] Wherein R 12 is a suitable group for the modified amino acids to be prepared, such as, but not limited to, alkyl, alkenyl, cycloalkyl or aromatic and especially methyl, ethyl, cyclohexyl, cyclophenyl, phenyl or benzyl, and X is leaving It is a leaving group. Typical leaving groups include, but are not limited to, halogens such as chlorine, bromine and iodine.
[48] Examples of acylating agents include, but are not limited to, acetyl chloride, propyl chloride, cyclohexanoyl chloride, cyclopentanoyl chloride and cycloheptanoyl chloride, benzoyl chloride, hypuryl chloride, and the like, acyl halides and aces Anhydrides such as but not limited to tic anhydride, propyl anhydride, cyclonucleoside anhydride, benzoic anhydride, hyplic anhydride, and the like. Preferred acylating agents include benzoyl chloride, hypuryl chloride, acetyl chloride, cyclohexanoyl chloride, cyclopentanoyl chloride and cycloheptanoyl chloride.
[49] Amino groups can also be modified by reacting carboxylic acids with coupling agents such as carbodiimide derivatives of amino acids, in particular hydrophilic amino acids such as phenylalanine, tryptophan and tyrosine. Further examples include dicyclohexylcarbodiimide and its homologues.
[50] If the amino acid is multifunctional, for example if it has one or more -OH, -NH, or -SH groups, it is optionally acylated by one or more functional groups, for example esters, amides or thioesters. ) Bonds can be formed.
[51] For example, in the preparation of many acylated amino acids, the amino acids are dissolved in a water soluble base solution of metal hydroxides such as sodium hydroxide or potassium hydroxide and acylating agents are added. The reaction time may be about 1 to 4 hours, preferably 2 to 2.5 hours. The temperature of the mixture is usually maintained at about 5 ° C to 70 ° C, preferably about 10 ° C to 50 ° C. The amount of base used per equivalent of NH group in the amino acid is about 1.25 mol to 3 mol, with about 1.5 mol to 2.25 mol per equivalent of NH 2 being preferred. The pH of the reaction solution is usually about 8 to 13, with about 10 to 12 being preferred. The amount of amino modifier used relative to the amount of amino acid is based on the total moles of free NH in the amino acid. Typically, amino modifiers are used in the range of about 0.5 to 2.5 molar equivalents, with about 0.75 to 1.25 equivalents being preferred per molar equivalent of the total NH groups in the amino acid.
[52] The modified amino acid production reaction is usually quenched by adjusting the pH of the mixture with a suitable acid such as concentrated hydrochloric acid until the pH reaches about 2-3. Leaving the mixture at room temperature separates to produce a clear upper layer and a white or greyish white precipitate. The upper layer is discarded and the modified amino acids are collected by filtration or decantation. The crude modified amino acid is mixed with water. The insoluble material is filtered off and the filtrate is vacuum dried. Typically, yields of modified amino acids range from about 30 to 60%, usually about 45%. The present invention also contemplates amino acids modified by multiple acylations such as diacylation, triacylation and the like.
[53] If the amino acid esters or amides are starting materials, they are dissolved in a suitable organic solvent such as dimethyl formamide or pyridine and reacted with amino modifiers for 7 to 24 hours in the temperature range of 5 ° C. to 70 ° C., preferably at about 250 ° C. . The amount of amino modifier used relative to the amount of amino acid ester is the same as for the above amino acids.
[54] Thereafter, the reaction solvent is removed under negative pressure and the modified amino acid ester is removed at a suitable base solution, such as 1N sodium hydroxide, at a temperature ranging from about 50 ° C. to 80 ° C., preferably about 70 ° C., for a sufficient time. By hydrolysis to cause the ester group to hydrolyze to produce a modified amino acid having a free carboxyl group, the ester or amide functional group can optionally be removed. The hydrolysis mixture is cooled at room temperature and acidified, for example with 25% aqueous hydrochloric acid, to bring the pH to a range of about 2 to 2.5. The modified amino acid is precipitated and recovered by traditional methods such as filtration or tilting.
[55] The modified amino acids can be purified by acid precipitation, recrystallization or fractionation on a solid column carrier. Fractionation was carried out using a mixed solvent such as acetic acid / butanol / water as the mobile phase, on a solid column carrier such as silica gel or alumina, using a trifluoroacetic acid / acetonitrile mixture as the mobile phase, and a reverse phase column carrier using water as the mobile phase. Ion exchange chromatography can be used. In addition, the modified amino acid can be purified by extracting with an alcohol having a low molecular weight such as methanol, butanol or isopropanol to remove impurities such as inorganic salts.
[56] The modified amino acid is usually dissolved in basic aqueous solution (pH ≧ 9.0), partially dissolved in ethanol, n-butanol and toluene / ethanol 1: 1 (v / v) solution, and not dissolved in neutral water. Alkali metal salts, such as sodium salts of modified amino acids, are usually dissolved in water at about pH 6-8.
[57] One or more amino acids in a polyamino acid or peptide may be acylated and / or sulfonated. Polyamino acids and peptides may comprise one or more acylated amino acids. While linearly modified polyamino acids and peptides typically comprise only one acylated amino acid, other polyamino acids and peptide configurations may comprise one or more acylated amino acids. Polyamino acids and peptides can be polymerized with acylated amino acids or acylated after polymerization.
[58] Sulfonated amino acids, polyamino acids and peptides are modified by sulfonating one or more free amine groups with a sulfonating agent that reacts with one or more of the free amine groups present.
[59] Examples of suitable sulfonating agents useful for preparing sulfonated amino acids, including but not limited to, sulfonating agents having the formula R 13 -SO 2 -X, wherein R 13 is an alkyl, alkenyl, cycloalkyl or aromatic But, but not limited to, suitable groups for the modified amino acids produced, X is a leaving group as above. One example of a sulfonating agent is benzene sulfonyl chloride.
[60] Modified polyamino acids and peptides may comprise one or more sulfonated and / or acylated amino acids. While typically used linearly modified polyamino acids and peptides contain only one sulfonated amino acid, other polyamino acid and peptide arrangements may comprise one or more sulfonated amino acids. Polyamino acids and peptides can be polymerized with sulfonated amino acids or acylated after polymerization.
[61] Delivery system
[62] Compositions useful in the present invention may include one or more active agents.
[63] In one embodiment, by briefly mixing one or more compounds or salts, polyamino acids or peptides with an active agent prior to administration, the compounds or salts or polyamino acids or peptides of the compounds to be used directly as a delivery carrier Can be.
[64] Dosage mixtures are prepared by mixing an aqueous solution of the carrier with an aqueous solution of the active ingredient immediately prior to administration. Alternatively, the carrier and the biological or chemically active ingredient can be mixed during the production process. The solution may optionally contain additives such as phosphate buffer salts, citric acid, acetic acid, gelatin and gum arabic.
[65] Stabilizing additives may be mixed in the carrier solution. In some drugs, the presence of such additives enhances the stability and dispersibility of the agent in solution.
[66] Stabilizing additives may be used at concentrations ranging from about 0.1 to 0.5% (w / v), with about 0.5% (w / v) being preferred. Examples of suitable but non-limiting stabilizing additives include gum arabic, gelatin, methyl cellulose, polyethylene glycol, carboxylic acids and salts thereof, and polylysine. Preferred stabilizing additives are gum arabic, gelatin and methyl cellulose.
[67] The amount of active agent is an amount effective to achieve the purpose of the particular active agent for indication of the target. The amount of active agent in the composition is usually a pharmacological, biological, therapeutic or chemically effective amount. However, when the composition is used in a dosage unit form such as powder or liquid, the dosage unit form comprises or is divided into several carrier / biological or chemical active agent compositions, Since it may comprise a therapeutic or chemically effective amount, the amount may be less than a pharmacological, biological, therapeutic or chemically effective amount. The total effective amount can be administered in cumulative units containing as a whole a pharmacological, biological, therapeutic or chemically active amount of a pharmacological, biological, therapeutic or chemical active agent.
[68] The total amount of active agent and in particular biological or chemical active agents used can be determined by one skilled in the art. Surprisingly, however, it has been found that for some biological or chemical active agents, the use of the presently disclosed carriers in the pulmonary delivery system provides extremely efficient delivery. Accordingly, less biological or chemical active agents can be administered according to the invention than those used in previous dosage unit forms or delivery systems, which still enable to achieve the same blood level and therapeutic effect. .
[69] The amount of carrier in the composition is a delivery effective amount and can be determined for any particular carrier or biological or chemical active agent by methods known to those skilled in the art. The effective amount of active agent and carrier in the composition may vary within the range contemplated and depends on the age, weight, sex, sensitivity, medical history, etc. of the individual. The nature of the active agent and the carrier, the specific activity of the agent (bioactivity / mass units), and the rate of absorption of the agent in the lungs should be considered, all of which contribute to the determination of a therapeutically effective dosage.
[70] After administration, the active agent present in the composition or dosage unit form is rapidly absorbed into the circulation. The bioavailability of the active agent is known pharmacological activity in the blood, such as, for example, an increase in blood clotting time induced by heparin, a decrease in circulating calcium levels induced by calcitonin, or a change in blood glucose levels induced by insulin. It is easily calculated by measuring activity. Alternatively, the circulation level of the active agent itself can be measured directly.
[71] Alternatively, if the target is lung, delivery is automatically effective. The bioavailability of the active agent is calculated by measuring the known active pharmacodynamic parameter of activity.
[72] Dosage unit forms also include, but are not limited to, excipients, diluents, disintegrants, lubricants, plasticizers, colorants, and any of water, 1,2-propane diol, ethanol, olive oil, or combinations thereof. It may comprise any one of the means (dosing vehicles).
[73] The delivery composition may also include one or more enzyme inhibitors. Such enzyme inhibitors include, but are not limited to, compounds such as actinin or epiactinin and derivatives thereof. Derivatives of such compounds are disclosed in US Pat. No. 5,206,384, which is incorporated herein by reference. Other enzyme inhibitors include, but are not limited to, aprotinin (trasilol) and Bowman-Birk inhibitors.
[74] The system is particularly useful for delivering a chemical or biologically active agent that is destroyed or diminished in the body of the animal to be administered and by conditions encountered before reaching the target point (ie the region from which the active agent is released). useful. In particular, the present invention is useful for pulmonary administration, such as by inhaler, or when improved delivery is desired of an active agent that cannot be delivered by the usual route. Improved delivery includes, but is not limited to, an overall increase in the amount of active agent delivered over time, an overall increase in biological response over time, and an increased delivery or response at a particular time, such as fast delivery or fast response of the active agent. Can be observed in several pathways.

[96] Preparation of Sodium Salt of Carrier C
[97] A 2- (4-aminophenyl) propionic acid (15.0 g, 0.084 mol, 1.0 equiv) suspension for methylene chloride (250 ml) was placed in a 2 L round bottom flask equipped with a magnetic stirrer and reflux condenser. Chlorotrimethylsilane (18.19 g, 0.856 mol, 2.0 equiv) was added in one portion and the mixture was heated to reflux for 1.5 h under argon atmosphere.

[125] Insulin was dissolved in distilled water with pH = 3 titrated with 0.01 N HCl. Distilled water at pH 7 was added when the solution became clear. Thereafter, the pH was adjusted to 7.5 with 0.01 NaOH.
[126] Carrier B was dissolved in distilled water at pH 7.4, sonicated for 2 minutes and the pH was adjusted to 7.4 with 0.1 N NaOH.
[127] 2. Animal
[128] Each rat was weighed, labeled with an indelible marker, anesthetized by intraperitoneal injection of a ketamine: xylazine: acepromazine cocktail containing 80 mg / kg, 10 mg / kg and 2.0 mg / kg. Put in. The rats were transferred to the operating table and placed on a thermo blanket controlled by a rectal probe for deep anesthesia.
[129] Catheter was inserted into the right cervical vein of each rat using silicone tubing, 200 μl of salt-containing heparin was flown into the cannula, and 100 μl of blood was collected to confirm the catheter opening. The cannula was then washed with 200 μl saline added heparin.
[130] An endotracheal tube was inserted using an optical fiber laryngoscope. A Hamilton syringe was attached to the endotracheal tube and used to drop the solution (100 μl) through the air passage. The endotracheal tube was removed after administration and the respiratory rate was monitored for the remainder of the study.
[131] Blood samples (500 μl) were taken at 0, 10, 30, 60, 90, 120 and 180 minutes, and about 200 μl of heparin added saline was flown into the cannula. Blood was collected in a 1 ml tuberculin syringe (containing 100 μl of 20 μl / ml heparin) and placed directly into a microcentrifuge tube.
[132] Blood samples were immediately centrifuged at 10,000 rpm for 4 minutes. An aliquot of about 30 μl was transferred to only 1 ml of silicone treated Eppendorf tubes and frozen until the study for subsequent glucose measurements was completed. The remaining samples were frozen at -70 ° C for insulin measurement (Ultra-sensitive RIA).
[133] analysis
[134] 1. Measuring glucose
[135] Fasting glucose levels were measured using the Ektachem DT Slide (GLU) method. The assay is based on the enzymatic catalysis of oxygen molecules and glucose followed by a second reaction to produce a highly colored red dye. The intensity of the color is proportional to the amount of glucose in the sample.
[136] 2. Pharmacokinetic Analysis
[137] Standard compartment and noncompartmental pharmacodynamic analyzes were performed for mean plasma insulin concentration over time. Compartmental analysis and noncompartmental analysis are usually performed simultaneously to verify the validity of the compartmental model.
[138] a. Compartmental analysis
[139] In the spray-intracheal (IT) administration of porcine insulin, the mean insulin concentration (C) was determined using a least-squares nonlinear regression method (PKanalyst, Micromath, Salt Lake City, UT). INS ) versus time pattern was fitted to the first compartment model, first absorption. The average insulin concentration was adjusted according to the following equation.
[140]
[141] Where A = Dk a / Vd (k a -k e ) is the drug concentration in the body at time 0, k a is the first order rate constant and k e is the first order rate constant.
[142] The area under thelung concentration-time curve = (AUC 0 → t ) was calculated by the trapezoidal law. Infinite interpolation was performed by dividing the final C ins by the late first-order rate constant. The total area under the curve was calculated as the sum of the two compounds.
[143] The elimination half-life is calculated from 0.693 / k e , where k e is the slope of the end of the log of the concentration-time pattern.
[144] b. Noncompartmental analysis
[145] Noncompartmental analysis of insulin plasma concentration over time was performed using standard techniques. The time (T max) and a peak C Pins (C max) of the peak C Pins from the unregulated average plasma concentration for the treatment (C Pins) was calculated. AUC was calculated by the trapezoidal law. MRT was not calculated because no data were available for the following intravenous administration to calculate pharmacodynamic parameters.
[146] 3. Pharmacodynamic Analysis
[147] Percentage minimum plasma glucose concentraion (% MPGC) and time T (T% MPGC) to obtain each% MPGC were determined from the mean blood glucose level versus time pattern for treatment.
[148] The area above the curve effect = AACE was calculated as follows.
[149]
[150] Where AUC E represents the area effect under the curve calculated using the trapezoidal law.
[151] Percentage total reduction in plasma glucose (% TRPG0 → t) at 0 → t was determined using the following equation.
[152]
[153] 4. Statistical Analysis
[154] AUC differences between insulin doses were tested for significance using Sheffe's multiple comparison test assuming α <0.05. The difference in AACE 0 → 3 (blood glucose level) between insulin alone and bound to carrier B was examined for significance using the Turkey's test and analysis of variance assuming α <0.05.
[155] Example 2a
[156] (i) Plasmainsulin and blood glucose-time patterns when 0.05 mg / kg of insulin mixed with carrier B 5 mg / kg were injected intratracheally instillation are shown in FIGS. 1 and 2 respectively.
[157] (ii) and (iii) FIGS. 3 and 4 and Table 1 below show blood glucose-time patterns and pharmacokinetic parameters when pulmonary endotracheal instillation of carrier B 16 mg / kg mixed with insulin 0.05 and 0.01 mg / kg, respectively, was applied. . When insulin was administered in the presence and absence of a carrier, a significant difference (p <0.05) of AACE 0 → 3 was observed. The% TRGP 0 → 3 for the insulin (combined with carrier B 16 mg / kg) doses 0.01 and 0.05 rose to 10.5 ± 1.5 to 36 ± 9% and 47 ± 10 to 65.7 ± 5%, respectively. There was no statistically significant difference in the% TRGP 0 → 3 value between 0.05 mg / kg of insulin alone and administration with 5 mg / kg of carrier B. This dose-effect relationship found for carrier B is likely due to the carrier's effect (increased bioavailability) on the pharmacokinetics of insulin.
[158]
[159] The data above suggest the potential of carrier B to significantly increase the bioavailability of insulin, and the influence of carrier B on glucose levels.
[160] (iv) Average insulin plasma concentrations with endotracheal injection droplets as a function of insulin dose are shown in FIG. 5. The pharmacokinetic parameters obtained from compartmental analysis and noncompartmental analysis are summarized in Table 2 below. Nonlinear curve fitting of mean plasma levels was best described as lowering the plasma concentration in all cases, decreasing first-order exponentially for first-order absorption. Modeling excellence was evaluated by comparing it with the relative model selection standard (MSC). The modified Akaike information standard allows a comparison of model suitability. MSC values range from 1.3 to 3.8 when indicating model suitability.
[161] The average peak plasma concentrations obtained in this study were 0.001 mg / kg (0.026 U / kg), 0.005 mg / kg (0.13 U / kg), 0.01 mg / kg (0.26 U / kg), 0.05 mg / kg (1.3 pigs) U / kg), 57.5 μU / ml (T max = 10 minutes), 18.8 μU / ml (T max = 20 minutes) for 0.1 mg / kg (2.6 U / kg), 0.5 mg / kg and 1 mg / kg, respectively , 71.3 μU / ml (T max = 10 minutes), 48.95 μU / ml (T max = 10 minutes), 213.1 μU / ml (T max = 10 minutes), 354 μU / ml (T max = 20 minutes) and 902 μU / ml (T max = 20 min), which shows close agreement with the values obtained after the curve modeling.
[162] The log plasma concentration-time plot (FIG. 5) as a function of insulin dosage was determined from previous reports obtained after intravenous administration of 0.1 u / kg bovine insulin to rabbits (t 1/2 = 30 min). Significantly longer half-lives (7.8 to 142.4 minutes; see Table 2) indicate a decrease in plasma concentration. The observation suggests the presence of a "flip-flop" case, i.e. absorption rather than ablation dominates plasma concentration reduction. However, this increase in absorption half-life does not imply that absorption is a rate determining step. Rather, this event may be the result of insulin converting from hexamer to monomer type or slowly “dissolving” as the insulin concentration per volume is increased.
[163] The area under the curve (AUC 0 → ∞ ) to infinity, obtained using the trapezoidal law, is 0.001 mg / kg (0.026 U / kg), 0.005 mg / kg (0.13 U / kg), and 0.01 mg / kg (0.26) U / kg), 0.05 mg / kg (1.3 U / kg), 0.1 mg / kg (2.6 U / kg), 2930, 1334, 5050, 5260, 15374, 67676, and 0.5 mg / kg and 1 mg / kg, respectively. 200230 μU min / ml.
[164] Multiple comparisons between doses using Sheffe's test showed no significant difference (p> 0.05) in AUC values. This may be due to a high degree of intersubject variability (see Standard Deviation for AUC in Table 2). By assuming that the degree of absorption of porcine insulin following pulmonary administration and that of human insulin following subcutaneous administration are equal, the relative bioavailability of the insulin used can be calculated. Based on these assumptions, the relative bioavailability of porcine insulin is 12.46%.
[165]
[166] Blood glucose-time modalities and pharmacokinetic variable (PD) data for various doses of instilled insulin are shown in FIG. 6 and Table 3 below. The result is that an increase in dose (from 0.01 to 1 mg / kg) significantly reduces the% minimum blood glucose (% MPGC) value from 70.2 to 13.1, without a significant change in the time T (T% MPGC) reaching the minimum. Shows. From 0 to 3 hours, the overall decrease in blood glucose (% TRPG 0 → 3hr ) (see Table 3) rises significantly from 10.5 to 73.7%, which is achieved by high levels of bioavailability as the extent of absorption increases with increasing insulin dose. It means.
[167]
[168] The intersubject variability (CV <30%) in the glucose response is less than the insulin response. Thus, insulin variability dampens as much as the appearance of hormones in the circulatory system translates to its biological activity.

A dose of 0.3 ml / kg of the pulmonary dosage composition at pH 7.3-7.6 was administered to five non-fasting normal mice by the following procedure. 1 and 1/2 Popper and Sons gavage needles were injected about a few centimeters below the neck of the animal. The tip of the needle was manipulated toward the ventral side where the needle could fall into the pocket and further manipulation led to trachea. The dosing solution was delivered through the needle when the needle was in the trachea.
