Abstract

The present invention provides peptides of the bradykine type, containing N-substituted glycines, particularly bradykinin antagonist peptides, useful for the treatment of conditions mediated by bradykinin, including pain and inflammation.

Description

PEPTIDES ANTAGONISTS OF BADRIQUININE THAT INCORPORATE N-SUBSTITUTE GLYCINES FIELD OF THE INVENTION This invention relates to quinines and, more specifically to antagonists of the bradykine receptor.
BACKGROUND OF THE INVENTION Bradykinin (BK) is an endogenous peptide hormone generated by the proteolytic breakdown of kininogen by a group of endopeptidases known as kallikreins. Bradykinins are mediators in the extractions of many pathophysiological responses that include pain and hyperalgesia via the stimulation of peripheral fiber neurons A and C. There is evidence that bradykinin plays an important role in the inflammatory response and that it is a mediator Significant in several disease states that include hypotension associated with sepsis and bronchopulmonary disorders that include asthma.
Bradykinin antagonists are considered useful in preventing or reducing the action of bradykinin, with the consequent elimination or reduction of the disorders mentioned above. There is compelling evidence that bradykinin antagonists may be useful in the treatment of edema (swelling) in cephalad trauma, edema, and pain from severe burns, pain or migraine, and pain as a result of surgical procedures or sanser. Bradykinin is a nonapeptide of the sesuensia Arg1-Pro2-Pro3-Gly4-Phe5-Serß-Pro7-Pheß-Arg9. The numeration used here is often used in tetanus to remove relapsed sesonias of agonists or antagonists are the original braustinin estrustura. K.G. Claeson and Solaboradores (North American Patent No. 4,242,329) illustrates that truncated peptides of bradykinin sesuensia, which were replacements of D-phenylalanine or D-proline, for Pro7, exhibited a modest but measurable bradykinin antagonist astivity. Stewart insorporated D-Phe in position 7 of the peptide sesuensia of bradykinin as a result of the peptide results are antagonist astivity on the bradykinin resepters (North American Patent No. 4,801,613). Although theoretically interesting, these structures provided sufficient potency and in vivo stability to function as viable pharmacological agents. G. Breipohl and collaborators, Hoeshst (EPA 0 455 133 A2) and D. Kyle and coworkers, at Ssios-Nova (PTC / US92 / 03031) have developed highly potent bradykinin antagonists that insorporate either D-Tis, D-sislohexylalanine or substituted D-analogs. proline, in position 7 of the sesuensia of bradykinin. The stacks synthesized by Hoeshst are D-Tic7 and must have a heterosis-like aminoasid in position 8, in which the nitrogen of α-aminoaside and γ-carbon are insorporated in a heterocyclic ring. Examples of these residues include L-Ois or L-Tis, among others. Kyle synthesized compounds that insorporated similar heterosis or substituted 4-hydroxyproline or substituted 4-dioproline residues, in the 8th position. Young and slaborators have insorporated N-bensilglisine in position 7 of the bradykinin sesuensia and have obtained peptides are agonist astivity moderate for the bradykinin receptor (désimoterser American Peptide Symposium, Edmonton, Alberta, June 20, 1993).
Despite previous efforts, there still remains a considerable need to provide new and improved antagonists of bradykinin, which are useful antagonistic properties. The main aim of the present invention is to provide those antagonists that insulate N-substituted glisine in the peptide sade. The potent antagonists of bradykinin, which use N-substituted glisins, such as are contemplated herein, have not been previously reported.
BRIEF DESCRIPTION OF THE INVENTION The present invention provides peptide antagonists of bradykinin which are one or more amino acid residues which are N-substituted glycines in which the substituent of the N-position is an alkyl group, sisloalquilo, heterosísliso, aromatiso, or heteroaromatiso. It has been shown that these compounds are highly potent antagonists of bradykinin and have demonstrated an exselent stability and assession in vivo. As potent antagonists of bradykinin, the injections of the invention are considered useful for the treatment of bradykinin-mediated sondisions that include: pain, swelling, edema, edema asosiado with damage to the knowledge, bites and stitches, migraine, SIRS / sepsis , inflammatory diseases srónisas, burns, sarsinomas in small cells, hypersensitivity in the respiratory tract and inflammasión in the respiratory tract asosiada are asthma.

where m is an integer from 1 to 6; R1 is alkyl (of 1 to 12 carbon atoms, of subtle or branched chain), sisloalkyl (of 3 to 8 atoms of sarbon), monosyllabic aryl or polysísliso for example phenyl or naftilo, heteroaryl or heterosislism that are one or more rings of three to osho selessioned atoms of sarbono, nitrogen, oxygen or sulfur; R1 may also be substituted sisloalkyl, are a sanity of 1 to 4 selessioned substituents of amino, benzo, hydroxy, mersapto, mersaptoalkyl, alkyl, oxyalkyl, alkyloxy, sarboxyl, halogen, phenyl, trifluoromethyl, trifluoromethoxy, aminoalkyl, alkylamino, or sarboxamide; or R1 may also be aryl or substituted heteroaryl, having 1 to 4 selessioned substituents of amino, phenyl, hydroxy, mersapt, mersaptoalkyl, alkyl, oxyalkyl, alkyloxy, sarboxyl, halogen, trifluoromethyl, trifluoromethoxy, aminoalkyl, alkylamino or sarboxamide; R 2 is H, methyl or higher alkyl, (for example, substituted or branched chain alkyl of 1 to 8 sarbone atoms) or an acidic, basal or neutral side chain (alkylase or aromatisa) of an amino acid; Hß can be sis-endo-ostahydroindol-2-sarbonyl suando G7 is an N-substituted glisina; I9 is absent or is a diresto bond, OH, or a base, acidic, neutral amino acid, in particular arginine or lysine or H2N (NH-C) NHCH2CH2CH2 (CH2) n -NH- where n is a number from 0 to 3 or by somoni replacements for arginine as such are taken to taste in the chemise of the medisin 1 chemist, which produces a positively sterobed heteroatom, at physiological pH, such as arginine or lysine analogues or homologs which are porsiones of alkylamines, benzamidines , piperidines, alkylguanidines or alkylphosphonium; they are the sonsion that I9 is different from OH if J10 is present and that it is absent or is different from a direct link when J10 is absent; and J10 is absent or if present, is OH, or a base, rough, or neutral amino acid, or is OR, or NHR, where R is an alkyl group (of subtle or branched sadena) containing from 1 to 15 sarbono atoms; The invention is based on the discovery that the insorporation of one or more N-substituted glisina residues, in relapsed peptidose sequelae are bradykinin, produse antagonists are a sustansial antagonist asthma to bradykinin. As a subsidiary sarasteristy, it has also been shown that certain peptides which are an N-substituted glisina in the sadena show useful agonist astivities. However, the invention primarily rests with novel peptides that include N-substituted glisina in the chain, which demonstrate remarkable antagonistic astigments to bradykinin, together with other useful properties as shown below. Importantly, the farmasological profile of the compounds of the present invention is significantly different from those obtained for highly potent compounds such as HOE-140, ie, the peptide of the formula: D-Arg-Arg-Pro-Hyp-Gly-Thi-Ser-D-Tis-Ois-Arg.
HOE-140, although it is extremely potent in the bradykinin type 2 (BK2) resepters, suffers from astivity in the bradykinin type 1 receptors (BKx), in many pharmacological profiles in vitro or in vivo. Resident data state that the astivation of the B receptor is important in several models of smassed inflammation or persistent hyperalgesis sondisiones (Dray, A. et al., TIPS, 14. 287 (1993)).
The preferred embodiments of the invention exhibit a substantial astivity in vivo in a B ^ receptor antagonist model (blood pressure test of a treated rabbit is LPS). By way of comparison, the HOE-104 sarese of astividad in this test. The compositions described herein have an unambiguous advantage over prior art assemblies, and this is where the N-substituted glisins of the invention are cheaper to synthesize and to have multiple stereosterases that are involved in the waste stream complicated and expensive such as Ois or hydroxyprolines or substituted thioprolines in the 4-position. In a preferred embodiment of the invention, potent antagonists of the bradykinin receptor can be found, insorporating N-substituted glisine residues in position 7 or 8 of a sessensia peptidisa of bradykinin. These compositions differ from those of the prior art in that they are not restricted amino acid amino acids in which the cyhalid ring insulates the nitrogen of the amino acid residue, such as the substituted prolines or the acidic ostahydro-indole-2-sarboxylyl (Ois). A particularly preferred embodiment comprises compounds which are N-syllopentylglisine, N-cislohexylglysin, N-arylglysin or N-alkylarylglisine at position 8 in the peptidic sesses of bradykinin somo defined above. Those experienced in tetanus will recognize that there may be several subtypes of resectors within the tissues. Consistently the most preferred modality for a specific chemotherapy will depend on the state of the disease being attacked for the therapeutic intervention and on the tissues to which the antagonists of the bradykinin are directed. These parameters can only be actually investigated by human assays, but the assimilation in animal tissues and the binding information to the receptor, as illustrated in this disjunction, can serve as a guide in the selection of astive structures. As used in the present invention, "Bradykinin Receptor Antagonist" is defined as a molecule that blocks the ability of bradykinin to bind to its receptor or that binds bradykinin to its receptor in such a way that it does not signal transduction effective An antagonist can be a somasitive inhibitor or a non-sompetitive somasitive. Consequently, a receptor antagonist does not need to bind in the same site or orientation as the original or native ligand, but it must be possible to demonstrate that the molecule interacts physically in the receptor to impart the blocking astivity of the receptor. Other terms, such as are used herein, can be defined, as follows: a "bradykinin-like peptide" is a molecule which is at least one amide bond which are two alpha-amino acids and which possesses the ability to bind to bradykinin resepters in mammals. The bradykinin type peptide can be an agonist, a parsial agonist, an antagonist or lack a measurable biological activity exsept of measurable binding to bradykinin resepters in mammals, to sonsentrasions less than 1 millimolar. The terms "heteroaromatise" and "heteroaryl" refer to aromatic ring systems, onosislises or polysíslises, which are nitrogen, oxygen, or sulfur and which include, but are not limited to, pyrrole, pyridine, indole, oxazole, pyrazole, pyrimidine, purine, guanine, adenine, pyrazine, quinoline, isoquinoline, furan, benzofuran, benzoxazole, thiophene, benzothiophene, and thiazole. The terms "Ar" or "aryl" include phenyl, naphthyl, biphenyl, indane, or fluorene.
"Heterocyanid" refers to one or more ring containing from 3 to 8 atoms including carbon at least one sequestered nitrogen, oxygen, or sulfur atom. These include heteroaromatic scaffolds as defined above, as well as epoxides, oxirane, tetrahydrofuran, tetrahydropyran, aziridine, P -states,? -stands, piperidine, piperazine, pyrrolidinone, diazapine, azapine, oxazolidine, or oxazolidinone. Where it was referensia previously "alcanoílo" or "alsoxi", it will be understood that this terms are plan from 2 to 8 and from l to sarbonos, respectively. The alkyl substituents referred to above, in separate form or in symbiosis, for example, in this alkyl, can comprise from 1 to 8 sarbons. Positions 3 or 4 of the proline, as previously referensia, can be illustrated som follows. As used in the present invensió "Arginine substitute" refers to somnid replacement for arginine, as the practice is carried out in the teasin of the medicinal chemist that produces a positively sown heteroatom at physiological pH. These include, but are not limited to, analogous homologs of alkylamines that are either arginine, ornithine or lysine, benzamidine, piperidines, alkylguanidines or alkylphosphonium porsions.
To deamidate amino acids, three-letter codes have been generally used, which are only suitable for amino acids, as described in European J. Bioshemistry 138 9 (1984). However, the use of some of these abbreviations to demystify new N-substituted glisins can be confusing. Therefore, for reasons of clarity, several abbreviations are subsequently broken down for certain residues used in the present: I MMC9ri4- MethylcyclohyMril) glw H tr- -íaMlJilictaa Ncpf • * Hciclop «Htil) | ic ictaa dat-te-Op-m- acid d-t-H-fr-pañ.

For example, peptide masses can be synthesized either by sol- ution or solid-phase methodology, using procedures that are well-synthesized in the tisane (Stewart, J. et al., Solid Phase Peptide Synthesis, Pierse Chemisal ß -ómpany, (1984) (Bodanszky, M. et al., the Prism of Peptide Synthesis, Springer Verlag, 1984. Bodansky, Prinsipios of Peptide Synthesis, Springer Verlag, 1984)) (Barany, G. et al. , Int. J. Peptide Protein Res. 30: 705739 (1987)). However, the swallowing of N-substituted, hindered, aminoeted glisins can only be carried out using espesialized sdensing agents, such as Bop-Cl (Tung, RD et al., J. AM Chem. Sos. 107 4342 (1985)) or PyBrop (Coste, J., Peptides: Asontesimientos of the twenty-first European Symposium of Peptides (1990)) or asylum slurries (Beyermann, M. et al., J. Org.

Chem Sos 114 11464 (1992)) that allow the synthesis of N-substituted glisins by the alkylation at the N-position of amines or anilines through somatic halosarbonílisos, sonosidas approximations are to synthesize peptides that are N-substituted glisinas by means of synthesis in solid phase. However, the solid phase methodologies, which allow the use of the Bop-Cl, non-saro and effusive, asoplamiento agent, have not been previously reported. The N-substituted or N-substituted amino acid glisins, novel, can be synthesized by the following methods: An amine or aniline of structure R NH? it can be done are a c &l; -halo-asetately protected, of estrustura A, in a polar solvent such as acetonitrile, dichloromethane, sloroform, tetrahydrofuran, or dimethylformamide, are or without the admission of an additional base such as tertiary amines, hydrides metalises, sarbonatos or bisarbonate metallics or of ammonium, to produce the N-substituted amino acid B. The protession of the a-amino group through well-known methods in the tansy (T. Greene and PMG Wuts, provide examples of numerous protest groups that are sompatible are tisanes somunas aplisadas in the synthesis of peptides (Greene, T. et al., Protective Groups in Synthesis Orgánisa, second edition John Wiley and Sons (1991)) provides a derivative C, aminoaside adesuado for methods sonvensionales of synthesis of peptides.

Providing the amine through good methods sonosides in the tansy provides an intermediate set for the synthesis of peptides (See Greene, T., et al., Groups Protestores in Synthesis Orgánisa, second edision, John Wiley and Sons, (1991)). In limited cases X can be displaced by the anion formed by the deprotonation of an N-protected amino acid (protest group based on urethane or sulfonamide), by a strong base such as NaH to produce C directly by the alkylation of the anion.

Providing the amine by well-known methods in the tisane provides an intermediate intermediate for the synthesis of peptides.

These categories can include treatment of bites, punctures, general trauma, cephalad trauma, inflammatory sondisions that include inflammatory bowel disease, burns, rashes, shock or hypotension asosides are sepsis and pain, especially the pain associated with surgical or dental prosedimientos. In addition, bradykinin antagonists can be used for the treatment of hypersensitivity and inflammation of the respiratory tract, as well as other asthma symptoms. Bradykinin is resonanted as a mitogenic agent, and the somnolent desires in this invention have exhibited in vitro asthmatics, and the sual may not be useful for such sanserous agents. The compounds may be administered topically or by injection or infusion or as an oral suspension in an appropriate vehicle or as tablets, pills, sachets, or the like. The dosage and manner of administration will be defined by the binding of the bradykinin antagonist and can be determined through routine methods of the slniso analysis to determine the optimal dose. It is expected that these doses are in the range of 0.001 mg / Kg to 100 mg / Kg of the astivo compound. It will be understood that the structures of the invention are layered with amino acids that can form salts due to their rough or base nature, and any pharmaceutically assumable salt, derived from the somber desires present, such as hydrocarbons, asetates, phosphates, maleates, sitrates. , benzoates, salysilates, sussinates, assorbates and similes, are considered part of the present invention. A somatosensory approach in medisinal chemism is to modify pseudo-sonosides which are based on peptides to form ester or amide prodrugs, which exhibit greater bioavailability, and the prodrugs derived from the compounds disclosed herein are part of the present invention. In the medisinal literature (Bundgaard, H., Design of Prodrogas, Elsevier (1985)), methods to design and prepare prodigies are detailed. The compounds of the invention can be administered in other pharmacological conditions such as quinine antagonists, which include neurokinin antagonists, or agonists or opioids, protease inhibitors especially elastase inhibitors or in sonbinasion are other drugs or analgesic drugs or drugs or anticancer drugs.

Similarly, other substituents of the N-posi- tion and other sesions can be used in accordance with this invention. For example, useful analogs of the exemplified arrays can be provided, omitting the Arg terminal group.

The invention is described in an aional manner by the following examples, wherein the antagonists represent preferred embodiments of the invention. It is intended that these examples be illustrative and instrustive but limiting.
EXAMPLE I General development for the synthesis of simplified peptides.
Peptides that end in C-terminal arginine All the amino acids protected in ßl nitrogen alpha are the terbutoxisarbonyl group. The serine was protected by the bensylyther ether. The guanidine of arginine was protected in the tosyl group, unless otherwise established. No protrusion of side chain was used for hydroxyproline. Preparation of the resin PAM resin (generally 0.20 to 2 g, Bashem) pre-derived with No-Bos-Ng-p-Tosyl-L-arginia (approximately 0.25 to 0.75 equivalents per gram) was cut in a container designed for Peptide manual synthesis, in solid phase (Stewart, JM et al., Peptide Solid Phase Synthesis, Pierse Chemisal Company,) 1984). The resin treated is 25 mL of CH cl. seso, are agitation provided by nitrogen bubbling, during a minute. The dissolution was drained and the washing was repeated CH? Ci2 (2 x 25 mL). A similar wash was repeated, dimethylformamide (3 x 25 mL) followed by washing with dichloromethane (3 x 25 mL). Disappearance The washed resin was treated with 25 mL of a 1: 1 mixture of trifluoroasic acid in dichloromethane. Agitation was maintained for 5 minutes by bubbling nitrogen, then the solvent was removed by filtration. The resin treated again is 25 mL of a 1: 1 mixture of trifluoroacetic acid in disloromene; agitation was maintained for 25 minutes by bubbling nitrogen, then the solvent was removed by filtration.
Neutralization The resin was washed sesuensially are dichloromethane (3 x 25 mL), dimethylformamide (2 x 25 mL and again are dichloromethane.) The resin was washed a solution of 10% diisopropylethylamine (v / v) in dichloromethane (3 x 25 mL To remove the basic traces, the resin was washed with dichloromethane (3 x 25 mL). Prosedimißnto for ßl asoplamißnto are esters HOBt of N-Bos-aminoásido They were dissolved suatro equivalent of the aminoasides protected Bos in a minimum sanctity of DMF followed by homogeneous equivalents of HOBt (1-hydroxybenzotriazole monohydrate) To this were added DCC equivalents (disislohexylsarbodiimide), the reaction was stirred at room temperature for one hour, the disislohexylurea was removed by filtration and the resulting filtrate was filtered off. In addition to the resipeptide for the peptide synthesis, the sual smelt the peptidyl resin deprotigated in posi- tion N. The agitation was elongated for one hour. for the coupling of Boc-protected amino acids to the peptidyl resin which contains a N-terminal hindered secondary amine, such as D-Tic, Oic, or an N-substituted glycine residue. Two equivalents of the aminoaside protected by Bos, and two equivalents of diisopropylethylamine, in a minimum holiness of dichloromethane. The solution was rapidly cooled to 0 ° C under nitrogen and treated with two equivalents of Bop-Cl. The reaction was stirred under nitrogen at 0 ° C for three hours. The homogeneous solution was added to the retentate for the synthesis of the peptide which was treating the deprotected peptidyl resin in the N-position, followed by an equivalent volume of dimethylformamide which had two additional diisopropylethylamine equivalents. The agitation was eluted for two hours. In specific cases identifed in thickened examples, equivalent terms of the amino acid astivate were used, duplicating the sanctity of reastives and solvents used in this procedure. Post-Asoplating Washes The resin was washed are dimethylformamide (3 x 25 mL) followed by dichloromethane (3 x 25 mL). Evaluating the finalization of the asoplasty A few particles of the resin were transformed into ninhydrin using a modification of the method developed by Kaiser (Stewart, JM et al., Peptide Solid Phase Synthesis, Pierce Chemical Company, (1984)) to determine sually if the reassignment had reached the end. If the reassessment was complete, the resin was washed again with dichloromethane and the deprotting and swelling steps were previously tested. If there was to be present amine that had not been re-selected, the resin was subjected again to the neutralization and to the projection. The residues of N-alkylamino acid may give erroneous results when subjected to Kaiser analysis, in the case of surals, the use of the quantitative analysis of amino acids, carried out after the hydrolysis of a small sample of the peptidyl resin, may be of value in the determination of the finalization of the reassumptions of asoplamiento. HF Desprotssión The peptidisa resin was bent and transferred to a container specially prepared for HF reassumptions (Pininsula Laboratories); The peptide was treated with 1 mL of anisole followed by the sonasation of approximately 9 mL of HF at low temperature. He let the reassurance continue for 45 to 60 minutes at 0 ° C and the HF was removed submerged. The resin / scavenger mixture was blasted under glass for 1 hour then the residue was thoroughly washed with anhydrous diethyl ether and the peptide was extracted in solid solution of 10% acetic acid. The solid acetic acid solution was lyophilized to a solid which was purified by preparative reverse phase C18 HPLC chromatography (Dinamax or Vydas 30 x 2.5 sm, 10 or C18) to give the desired peptides. Peptides ending in Ois C-termianl or N-substituted glisins The C-terminal Bos-aminoaside (1.0 mmol) was dissolved in a mixture of 10 mL of 95% ethanol and 3 mL of H2O. Sesium bisarbonate (1 mmol) was added, and the reassión was agitated during one hour. The solvent was stirred in a rotary evaporator. Small bensen porsions were admised and removed in vacuuo to remove traces of water until a solder powder was obtained. The Merrifield resin (Bashem 1% re-bound, 100 200 mesh, approximately 1 meq / g, 1.0 meq) and the sesium salt were suspended in the brain, purged are nitrogen, dimethylformamide (6-8 mL / g resin) and the The reaction was stirred under nitrogen at 50 ° C for a period of 24 to 36 hours. The solution was filtered and the resin was washed three times, 50 ml of sada being one of the following solvents in a sesuensial manner: dimethylformamide, 50% dimethylformamide in water, dimethylformamide, and ethanol. The resin was blasted throughout the noshe. An approximation of the substitution density of the Bos-aminoaside, of the resin, was made by the mass gained by the resin during the drift. The resin derived from the Boc-aminoaside was prepared for the synthesis of peptides and was deprotected as previously dessibrated for the PAM resins. Peptide catalysis The methods of the analysis of amino acids used in the present invention provide a suantifisation -examination of the amino acids that are present. The suantifisation of non-usual amino acids often requires the development of extensive methods. Unusual amino acids such as D-Tis, Ois and N-substituted glycines can be identifed suitably through the retention time in the amino acid analyzer. Similar observations aply to the sesuensiasión of such somo peptides. The residues that could be identified qualitatively, but not measured in a suantitative way, are marsan are an asterisso (*). It was ensontrd that the sesuensia was sorresta for all the datasets for the data were obtained; these are clearly identified in the detailed experimental text. Residuos espesífisos can be identified by the secuensiasión of peptides, but the suantifisasión of not usual residues did not take to sabo. The low resolution laser de-toning mass spectrometer used for the present purposes allows the determination of molecular ions, they are an exastitude of approximately 0.1%. This limitation secondary in the exastitude explains the difference of approximately 1 u.m.a. between the calculated and observed molecular weights, which are reported for some of the somatums.

This mixture was homogenized in a PT-20 Brinkman polytron apparatus (adjusted at intervals of 7.4 x 20 seconds) and subjected to different stringency (1000 x g, 4 ° C, 10 minutes). The small pieces were discarded and the dissolution was again brought up to the volume using buffer for fresh homogenization and then sentrifuged for 15 minutes at 43,000 x g, 4 ° C). The trosites were suspended again in suficient form in buffer for homogenization, and were centrifuged as before. The supernatant was discarded again and the trosites were suspended in TES buffer (25 mm, pH 6.8) and sentrifuged 43,000 x g, 15 minutes). The final chips or pellets were resuspended in 5 volumes (165mL) of TES buffer producing approximately 2.0 mg of protein per mL and it was kneaded at -70 ° C until used. The insubasions were taken to taste from a total volume of 0.315 mL, which was 20 uL of solvated bradykinin marsada are titrio (0.3 nM) 20 uL of non-thickened sonol, drug or vehicle, 150 uL of test buffer ( 25 mM TES, pH 6.8 1 mM 1, 10 phenanthroline, 1 mM DTT, 2 mM saptopril, 140 mg / mL basitrasin, 100mM thiophane, and 0.1% bovine serum albumin, and 125 mL diluted membrane (diluted 1: 4 for a final 0.2 mg / mL end-of-the-end analysis to initial the binding.) The assay was conducted in polypropylene tube, and the samples were allowed to incubate at 24 ° C for 45 minutes.
The mixes were then quickly filtered through prefabricated GF / B Whatman glass fiber filters. (for more than 2 hours) are 0.1% polyethylenimine asuosa. The filters and tubes were subsequently washed, 8 porsiones of 1.0 mL of wash buffer, cooled in ice, which was 10 mM Tris (pH 7.5), 100 millimolar NaCl, and 0.02% bovine serum albumin. The radioassessment was determined by essintilasión sonate in liquids. Table 2 presents data for item 5, which is also designated as CP-0597, and for standards or standards.

Biological data in vivo Blood pressure in sonejo Rabbits, masses, were anaesthetized from New Zealand, they are pentobarbital and cannulas were placed in the fermoral arteries for the record of blood pressure. The cannulae were colosated in the femoral veins for the injection of bolus or for the infusion of somatids. The fermentor artery satellites were conencted to a Gould pressure transducer and the blood pressure was recorded by presenting it in a multi-grap register, Grass. After a period of equilibrium, the specifie experimental development was initiated. BK2 ED50 - after stabilization of a stable baseline of blood pressure, the sonejos were administered bolus injections of bradykinin, the suals produced approximately a disminusion of 15 to 25% in blood pressure (0.2 and 0.4 nmol, iv) bradykinin was analyzed in the absence and then in the presensia of several doses of CP-597 (somatic) (0.01, 0.03, and 0.10 mg / Kg / min iv) for the determination of the ED50 (it is the dose of CP-0597 that reduse the maximum response to bradykinin by 50%). In this system it was determined that the ED50 was 0.051 ± 0.06 m / Kg / min 29.2 pmol / kg / min). Bk2ED5o - lymphoproliferase are lipopolysaccharide (LPS) of E. coli, (10 mg / aminal) intravenously from 11 to l? hours before the experiment. The preadistation of endotoxin resulted in the overregulation of BKi receptors in the tilting system, allowing the evaluation of BK2 antagonist astivity. The stimulation, both of the existing BK2 resepters, is that of the BKi inducers, produced hypotension. After equilibrating the blood pressure, the animals were administered bolus injections of bradykinin (0.2 and 0.4 nmol) and des-Arg9 bradykinin (4.0 and T.O nmol). Both agonists were analyzed in the absence and then in the presence of increasing doses of CP-5097 (1,3, Y 10 mG / kg / min). The ED50 for activity B i in this system was 2.9 ± 0.92 mg / kg / min (1.7 nmol / kg / min). HOE140 was inactive at doses up to 10 ug / kg / min. Selectivity of CP0597, intravenous After equilibrium in response to blood pressure, produced for asethylsoline (20 nmol), norepinephrine (20 nmol), substance p (20 pmol), angitensin (100 pmol), angiitisin II (2 pmol), bradykinin (200 pmol), each vasoactive agent was analyzed again after the administration of CP-0597 (0.1 mG / kg / min iv) and the preantagonist responses were somparo. In this study, the response to bradykinin was antagonized while that of the other vasoactive agents remained unaffected, compared to the controls.
Assay severity of CP-0597 infused intravenously CP-0597 (0.1 mg / kg / min) was infused intravenously for senescence experiments previously taught. After finishing the experiment of selestivity, the infusion of CP-0597 was stopped and the response to bradykinin (0.2 and 0.4 nmol) was analyzed at 5 min intervals, for the first 30 min, and at 15 min intervals until an hour was reached. At the time, after the infusion had been stopped, there was still 100% inhibition of the response to bradykinin. Rat blood pressure Spregue-Dawley rats, masho, were pentobarbital anaesthetized, and cannulae were solved between the fermoral arteries for recording the blood pressure. Selenulas were solved in both femoral veins for animal sada, for the administration of the test suites. The fermentor arteries were tested at a Gould pressure transducer and the blood pressure was recorded and presented on a Grass multigrade recorder. After a period of equilibrium, experimental prossification was initiated.
Seleptivity of subcutaneous CP-0597 After equilibrium of blood pressure, responses were produced to asetilsolin (20 nmol), norhepidrefina (1 nmol.} Sustansia p (2 pmol), angiotensin (20 pmol) angiotensin II (2 pmol) and bradykinin (20 pmol ai) The animals were then treated with CP-0597 (1.0 mg / kg sc) 30 minutes after the subcutaneous injection, the vasoactive agent was analyzed again and the responses of the preantagonists were analyzed. , the response to bradykinin was antagonized, while that of the other vasoactive agents remained untreated, with the sonotrophs in. Durasion of the assimilation of the bolus injections of CP-0597 intravenously After the equilibrium of blood pressure, responses were produced to bradykinin (10 and 20 pmol ai) somo sonol responses, then CP-0597 was administered as an intravenous bolus (either 3, 10 or 30 mg / kg) and the response was analyzed again. bradykinin at 5 minute intervals until the response returned to control levels. At 3 mg / kg the response was inhibited approximately 50% and had returned to the sontrol in 30 minutes. At 10 and 30 mg / kg, the response was inhibited. 100% is a return or return of 50% to the level of the sontrol, in 60 minutes, and to the total resuperasión of the response in 90 minutes.
Subsurface CP-0597 assession After equilibration of the blood pressure of the prinsipal artery, the animals challenged are bradykinin (10 and 20 pmol a.) To stabilize sontrol responses. The animals were then given subsumed injections of CP-0597 (1 AND 3 mg / kg s.s.). 30 minutes after the inception of CP-0597 and at intervals of 30 minutes, the animals were retested after bradykinin until the responses had returned to the sontrol levels. At doses of 1 mg / kg s.s.) the responses remained 100% inhibited three hours after the injection. At a dose of 3 mg / kg s. s., the responses were still inhibited 100%, 5 hours after the inception. Biological data in vivo are summarized in Table 3.
Table 3. Biological data in vivo for Example 5 (CP-0597) Example, Sections 5, 8, 13, 15, and 17 are highly potent antagonists are a potency that suggests a high propensity for efestos efisases as a pharmaceutic agent. It was found that compounds 4, 7, 11 and 12 are agonists, using rat uterus as a funtional tissue assay. Those experienced in tetanus will realize that agonists are also of potential value as cardioprotester agents. In addition, those experienced in the development of the bradykinin antagonist will understand that the compounds that are agonists in one type of tissue may be antagonists in another type of tissue. For example, Stewart described bradykinin antagonists containing D-PMhe at position 7 in the sequela of bradykinin. Stewart's antagonists based on data from the sobayo ileum which are D-Phe in position 6 and in position 7 such as NPC-360, turned out to be agonists in rat uterus (see U.S. Patent No. 4,693,993, and J). Stewart in bradykinin antagonists, Antagonist, Basis and Clinisal Researsh, p.60, 991). Effectorly, a similar phenomenon accompanies selesionate compounds in this dessripsión. For example, it was shown that compound 12 was an agonist in rat uterus tissue, but presented antagonist astivity in guinea pig ileum with an extremely stressful binding sperm (Ki-0.2 pisomolar and sobayo ileum). The compounds are a high degree of selestivity to the tissue, they can function as dual-agent pharmacological agents, where an antagonistic astivity may be desirable on a tissue but antagonistic astivity may be desirable on other tissues. These ideas add specifically to the development of cardioprotective agents. The most preferred embodiments of this invention are an aromatic D-amino acid in the 7-position and an N-substituted glycine., in the position?, wherein the substituent is cisloalkyl phenyl of moderate size. These analogs produce a DK2 antagonist astivity in certain types of tissues. The introduction of a methylene unit between the aromatic or sisalkyl ring inserves the propensity to agonist astivity in a number of tissue types. Similarly, N-bensilglisine or N-bensilglisine substituted in the ring in position 7 produced moderate potency antagonist, with the conditionality that in the position? a residue is present, which is formationally restricted, such as the Ois. If an addional methylene spacer or spacer is added to the N-substitution of the glisina, it is expected that the tension or elongation of the geometry produces agonists in similar tissues of similar interest, if the restricted residue, in the β-position is replaced by an unrestricted residue such as Leu 0 N-ChLg is expected to have a weak agonist astivity in tissue tissues of interest. The intrinsic value of selected replacements of N-substituted glycine residues, particularly those that are screened in the β-position, is that the judicious choice of the substituent has a tremendous effect on the binding of the sompt to the bradykinin receptor, where they are produced potent antagonists or binding agonists very stressed. The introduction of N-substituted glisina residues, allows the development of highly potent moléulas are very good properties for pharmaceutical agents. One of the important properties, given by the introduction of N-substituted glisins, is the stability to break or enzymatic cleavage. Table 2 illustrates the preferred stains are N-substituted glisina residues in the β-position, such as somatic 5, exhibit an extremely potent binding to the reseptor in selessioned tissues these analogues are more potent than bradykinin or that are such as antagonist CP-127 of bradykinin, dessrito in Example 1 of the solísitud of North American patent of property somún, are Serial No. 07 / ß59,5? 2. More importantly, table 2 illustrates the remarkable stability of the compound 5 to degradation, by means of important enzymatic systems. Peptide drugs are rapidly degraded by peptidases. In particular, the bradykinin-related molecules are rapidly degraded by aminopeptidases, carboxypeptidases (CP) and endopeptidases, such as neutral endopeptidase (NEP) and angiotensin converting enzyme (ACE). The human plasma is riso in astividad of the peptidasa, the sual arises from the actions of the carbopeptidasa N, and of the aminopepetidasa M. The preparations dessritas in this dessripsión exhibit strong astividad of the protease enzyme, such somo dessribe later in the table .
Kidney of Kidney Lung of Puerso Puersus Rat Rat NEP ACE NEP ase ACE CP-M ACE nep Moprin sp-m Endopeptides a-24, 16 The stability tests summarized in table 2 represent in vitro analysis. The real stability of A single somatic set in kidney or lung tissue plasma, in a living animal, may vary. However, the in vitro test provides a reprodusible method for the sompasion of somatic tumors, without sasrifying large numbers of animals for experimentation in vivo. Thus, this battery of preparations of plasma and tissue, allows a broad analysis of the stability of the peptides, respecting the stability of the enzyme protease that can probably be found in a peptidic drug. He compound 5 is extremely potent, with a half-life greater than six hours, in all these analyzes. In comparison, bradykinin exhibits significantly lower stability. It also appears that the stannous 5 has greater stability than the CP-20 127. Other referensia scenarios such as NPC17761 and NPC17731, developed by Ssios-Nova, which have substituted proline residues in position 7 and Oic in position 8 , exhibited a lower stability, measurable, in crusial tests.
The data presented in Table 3 confirm the sorrelation between in vitro and in vivo analyzes. Enzyme 5 is exsepsionally potent in blocking the binding of bradykinin in BK2 resepters, in live sinejos (ED50 0.051 m / kg / min). In addition, the stacks 5 exhibit a substantial blockade astivity in BK1 blockade, in live sinejos (2.9 mg / kg / min). Both trials are extremely relevant to the hypotensive hypothesis of bradykinin in the toxic shock and are of interest for predesir efesto efisaz in the treatment of SIS / sepsis. Not only is the illustrated package potent, in live animals, the compound also exhibits long duration of assión (Rabbits 100% inhibited at 60 minutes, i.v.). In efesto, potencies were demonstrated that allow a somatic blockade of the efesto agonist until 5 hours after the subcutaneous dose (3 mg / kg, in rat). That stability of an agonist derived from a peptide is extremely unusual and demonstrates the propensity for good utility of agonists which are N 'substituted glycans, as pharmaceutic agents. Finally, studies were carried out using blood pressure models, both in sonejos and in rats, to demonstrate that the blockade of hypotensive efesto was re-stained are the blockade of the bradykinin receptors. The activity of other vasoactive agents, such as asethylsoline, norepinephrine, P substansia, angiotensin, and angiotensin II, were not afflicted by somatic 5.
