Abstract
The invention provides template-fixed beta-hairpin peptidomimetics of the general formula (I) or salts thereof
Description
The present application is a divisional application of the patent application having the title "template-fixed β -hairpin peptidomimetic having protease inhibitory activity" filed as 200580049141.1 filed as 17.2.2005.
Technical Field
The present invention provides template-fixed β -hairpin peptidomimetics comprising a template-fixed chain of 11 α -amino acid residues, generalized in that their position in the chain is Gly or Pro (4NHCOPhe), or of some kind as defined below. These template-fixed β -hairpin peptidomimetics are useful as inhibitors of proteases. They are particularly useful as inhibitors of different serine proteases, e.g., human cathepsin G, elastase or tryptase. Furthermore, the present invention provides a highly efficient method by which these compounds can be produced in a library format, if desired.
The β -hairpin peptidomimetics of the invention exhibit improved potency, oral bioavailability, improved half-life, and most importantly, high selectivity rates between different serine proteases, depending on the appropriate choice of certain types of α -amino acid residues and their position in the chain. Furthermore, these β -hairpin peptidomimetics exhibit low hemolysis and low cytotoxicity towards erythrocytes.
Background
Inhibitors of proteases are showing promising therapeutic utility in the treatment of diseases such as cancer (R.P.Beckert, A.Davidson, A.H.Drummond, M.Whittaker, Drug Disc.Today 1996,1, 16-26; L.L.Johnson, R.Dyer, D.J.Hupe, curr.Opin.chem.biol.1998,2,466-71; D.Leung, G.Abbenantete, and D.P.Fairlie, J.Med.chem.2000,43, 305-; c.albicans (C.Abad-Zappelero, R.Goldman, S.W.Muchmore, C.Hutchins, K.Stewart, J.Navaza, C.D.Payne, T.L.ray, protein Sci.1996,5,640-52), HIV (A.Wlodawer, J.W.Erickson, Annu.Rev.biochem.1993,62,543-85; P.L.Darke, J.R.Huff, adv.Pharmacol.1994,5,399-, hepatitis (J.L.Kim, K.A.Morgenster, C.Lin, T.Fox, M.D.Dwyer, J.A.Landro, S.P.Chemers, W.Markked, C.A.Lin, T.Fox, M.D.Dwy, C.Landso, S.S.P.P.J.P.J.Ser.

Since most proteases bind to their substrates in an extended or β -chain conformation, good inhibitors must be able to mimic this conformation. Thus, ideally, the β -hairpin mimetic is adapted to lock the peptide sequence in an extended conformation.
Among proteases, serine proteases constitute important therapeutic targets. Serine proteases are classified by their substrate specificity (particularly the type of residue found at P1) into: trypsin-like (positively charged residues Lys/Arg at position P1 are preferred), elastase-like (residues P1 areSmall hydrophobic residues Ala/Val) or chymotrypsin-like (large hydrophobic residues Phe/Tyr/Leu at P1). It is already available in the PDB database (PDB:www.rcsb.org/pdb) Those serine proteases for which protease inhibitor X-ray crystal data were obtained include trypsin, alpha-chymotrypsin, gamma-chymotrypsin, human neutrophil elastase, thrombin, subtilisin, human cytomegalovirus, protease a, achromobacter (achromobacter), human cathepsin G, glutamate specific protease, carboxypeptidase D, coagulation factor VIIa, porcine coagulation factor 1XA, mesenterico peptidase, HCV protease and thermitase. Other serine proteases of therapeutic benefit include tryptase, complement convertase, hepatitis C-NS3 protease. Inhibitors of thrombin (e.g. j.l.metha, l.y.chen, w.w.nichols, c.mattsson, d.gustaffson, t.g.p.saldeen, j.cardiovasec.pharmacol.1998, 31,345-51; c.lila, p.gloanec, l.cadet, y.herve, j.fournier, f.leborgne, t.j.verbeuren, g.denanteuil, synth.comm.1998,28,4419-29) and factor Xa (e.g. j.p.vacca, annu.med.chem.1998, 33,81-90) are being used as anticoagulants in clinical assessments, inhibitors of elastase (j.r.williams, r.c.falcon, c.knee, r.l.in, r.l.chem.1997, r.r.r.t.21-51, r.t.t.t. ghem.r.r.r.r.t.t.r.t.t.t.t.t.t.t.t.r.r.t. lung, r.r.r.r.t. t. r.r.t. r.r.r.t. r. 7, r.r. r. r.r.r. r. r.r.r.r.r.r. r.. Finally, cathepsin G and elastase are intimately involved in the regulation of the activity of cytokines and their receptors. In particular at the site of inflammation, cathepsin G, elastase and protease 3 are released from infiltrating polymorphonuclear cells that have a close temporal correlation with elevated levels of inflammatory cytokines, which strongly suggests that these proteases are involved in the control of cytokine bioactivity and availability (u.bank, s.ansorge, j.leukc.biol.2001, 69,177-90). Therefore, inhibitors of elastase and cathepsin G constitute valuable targets for new drug candidates, in particular for chronic obstructive pulmonary disease (Ohbayashi H, ephert Opin.Investig.Drugs 2002,11,965-980)。
Among the various proteinaceous serine protease inhibitors that exist, one is a 14 amino acid cyclic peptide from sunflower seed, known as sunflower trypsin inhibitor (SFTI-1) (S.Luckett, R.Santiago Garcia, J.J.Barker, A.V.Konarev, P.R.Shewry, A.R.Clarke, R.L.Brady, J.mol.biol.1999,290, 525-533; Y.Q.Long, S.L.Lee, C.Y.Lin, I.J.Enyedy, S.Wang, P.Li, R.B.Dickson, P.P.roller, Biorg.&Med, chem, lett, 2001,11, 2515-containing 2519) which show sequence and conformational similarity to the trypsin-reactive loops of serine protease inhibitors of the Bowman-Birk family. The inhibitor adopts a beta-hairpin conformation when bound to the active site of bovine beta-trypsin. SFTI-1 inhibits beta-trypsin (K)i<0.1nM), cathepsin G (K)i0.15nM), elastase (K)i105. mu.M), chymotrypsin (K)i7.4. mu.M) and Thrombin (K)i~136mM)。
We illustrate here the approach of inhibitor design, which involves the transplantation of a β -hairpin loop from a naturally occurring peptide onto a hairpin-inducing template. Based on the well-defined 3D structure of the β -hairpin mimetics, libraries of compounds can be designed, which ultimately lead to novel inhibitors that exhibit different specificity characteristics for several classes of proteases.
Template-bound hairpin mimetics have been described in the literature (D, Obrecht, M.Altorfer, J.A.Robinson, adv.Med.Chem.1999,4, 1-68; J.A.Robinson, Syn.Lett.2000,4,429-441), template-fixed peptidomimetics which inhibit serine proteases and methods for their synthesis have been described in International patent application WO2003/054000A1 and Descours A, Moehle K., Renard A, RobinJ.ChemBioChem 2002,3,318-323, but these previously disclosed molecules have not exhibited high selectivity and particularly high potency. However, the ability to generate β -hairpin peptidomimetics using combinatorial and parallel synthesis methods has now been established (L.Jiang, K.Moehle, B.Dhanapaal, D.Obrecht, J.A.Robinson, Helv.Chim.acta.2000,83, 3097-.
The above-described methods allow the synthesis and screening of large hairpin mimetic libraries, which in turn facilitates structure-activity studies to a considerable extent, and thus the discovery of new molecules with highly potent and selective serine protease inhibitory activity, oral bioavailability, low hemolytic activity on human erythrocytes, and low cytotoxicity.

The peptidomimetics of the present invention may also be enantiomers of the compounds of formula I. These enantiomers can be prepared by modifications of the above process in which all enantiomers of chiral starting materials are used.
The term "alkyl", as used in this specification, alone or in combination, refers to a straight or branched chain saturated hydrocarbon group having up to 24 (preferably up to 12) carbon atoms. Similarly, the term "alkenyl" refers to a straight or branched chain hydrocarbon group having up to 24 (preferably up to 12) carbon atoms containing at least one or up to four olefinic double bonds depending on chain length. The term "lower" refers to groups and compounds having up to 6 carbon atoms. Thus, for example, the term "lower alkyl" refers to a straight or branched chain saturated hydrocarbon group having up to 6 carbon atoms, such as methyl, ethyl, n-propyl, isopropyl, n-butyl, sec-butyl, isobutyl, tert-butyl, and the like. The term "aryl" refers to an aromatic carbocyclic hydrocarbon radical containing one or two six-membered rings, such as phenyl or naphthyl, which may be substituted with up to three substituents, such as Br, Cl, F, CF3、NO2Lower alkyl or lower alkenyl. The term "heteroaryl" refers to an aromatic heterocyclic group containing one or two five-membered and/or six-membered rings, at least one of which contains up to three heteroatoms selected from the group consisting of O, S and N, and which rings are substituted or unsubstituted; representative examples of such optionally substituted heteroaryl groups are as hereinbefore described for R77The definition section of (a).
The structural element-A-CO-refers to the amino acid building block which, in combination with the structural element-B-CO-, forms the templates (a1) and (a 2). The structural element-B-CO-is combined with another structural element-B-CO-to form a template (a 3). Template (a3) is less preferred in formula I. Templates (a) to (p) constitute building blocks having N-and C-termini positioned at intervals in such a way that the distance between these two groups may be between 4.0 and 5.5A. The peptide chain Z is linked to the C-and N-termini of the templates (a) to (p) via the respective N-and C-termini, such that the templates and chain form a cyclic structure, for example as shown in formula I. In the case where the distance between the N-and C-terminus of the template is between 4.0 and 5.5A as used herein, the template will induce an H-linked network which is necessary for the formation of a beta-hairpin conformation in the peptide chain Z. Thus, the template and peptide chain form a β -hairpin mimetic.
The beta-hairpin conformation is highly correlated with serine protease inhibitory activity of the beta-hairpin mimetics of the invention. The conformational nature of the stable β -hairpin of templates (a) to (p) not only plays a key role in selective inhibitory activity but also has a key role in the synthetic process as defined above, since incorporation of the template at the beginning or in the vicinity of the middle of the linear protected peptide precursor can significantly enhance cyclization yields.
The structural units A1-A69 belong to the class of amino acids in which the N-terminus is a secondary amine forming part of a ring. Among the amino acids encoded by the gene, only proline falls into this class. The configuration of the structural units A1 to A69 is (D), they are combined with the structural unit of the (L) -configuration-B-CO-. The preferred combination with respect to template (a1) is-DA1-CO-LB-CO-toDA69-CO-LB-CO-. Thus, for example,DPro-Lpro constitutes a prototype of template (a 1). Less preferred but still feasible are also combinations of forming the template (a 2): -LA1-CO-DB-CO-di-carboxylic acidLA69-CO-DB-CO-combination. Thus, for example,LPro-Dpro constitutes a prototype of template (a 2).
It will be appreciated that the structural unit-A1-CO-to-A69-CO-wherein A has the (D) -configuration carries a group R in the alpha-position to the N-terminus1。R1Preferably H and lower alkyl, R1Most preferred are H and methyl. One skilled in the art will appreciate that A1-A69 is shown in the (D) -configuration for R1Is the case for H and methyl, which corresponds to the (R) -configuration. Generalizing R according to Cahn, Ingold and Prelog rules1The configuration may also be represented as (S).
Except that R1In addition, the structural units-A1-CO-to-A69-CO-may carry the name R2To R17Of (2)And (4) a substituent. The other substituent may be H, which if not H is preferably a small to medium size aliphatic or aromatic group. R2To R17Examples of preferred values of (c) are:

The structural unit A70 belongs to the class of open-chain alpha-substituted alpha-amino acids, the structural units A71 and A72 belong to the class of corresponding beta-amino acid analogs, and the structural units A73-A104 belong to the class of cyclic analogs of A70. Such amino acid derivatives have been shown to bind small peptides in a well-defined reverse-turn or U-shaped conformation (C.M. Venkatachalam, Biopolymers,1968,6, 1425-1434; W.Kabsch, C Sander, Biopolymers 1983,22, 2577). Ideally, such Building Blocks or templates are suitable for stabilizing the beta-hairpin conformation in the peptide loop (D.Obrecht, M.Altorfer, J.A.Robinson, "Novelpeptide Mimetic Building Blocks and strands for effective Lead Finding", adv.Med chem.1999, Vol.4, 1-68; P.Balarlaram, "Non-standing amino acids in peptides and proteins engineering", Current.Opin.Struct.1992.2, 845, M.Crisma, G.Valle, C.Toniolo, S.Prubidad, R.B.Rao, P.Hbaltam, "beta-transition structures for structures of peptides of proteins, R.B.Rao, P.Hbaltam," beta-hairpin structures of proteins, proteins of proteins, J.1990, Al.35-J.1990, Biocoding.

Furthermore, the amino acid residues in the chain Z may also have the formula-A-CO-or the formula-B-CO-, wherein A and B are as defined above. Finally, Gly can also be an amino acid residue in chain Z, and Pro (4-NHCOPhe) can also be amino acid residues in chain Z, except possibly at the position of the interchain bond (H).
The group C comprises a compound having a small atomSize to medium size hydrophobic side chain groups (according to R for substituent72General definition of (d) amino acid residues. Hydrophobic residues refer to amino acid side chains that are uncharged at physiological pH and are rejected by aqueous solutions. In addition, these side chains are typically free of hydrogen bond donor groups such as, but not limited to, primary and secondary amides, primary and secondary amines and their corresponding protonated salts, thiols, alcohols, phosphonates, phosphates, ureas, or thioureas. However, they may contain hydrogen bond acceptor groups such as ethers, thioethers, esters, tertiary amides, alkyl or aryl phosphonates and phosphates or tertiary amines. The small to medium size amino acids encoded by the gene include alanine, isoleucine, leucine, methionine and valine.
The radical D comprises radicals having aromatic and heteroaromatic side chains (according to the formula for the substituent R)73General definition of (d) amino acid residues. Aromatic amino acid residues refer to hydrophobic amino acids having a side chain containing at least one ring with a conjugated pi-electron system (aromatic group). In addition, they may contain hydrogen bond donor groups (such as, but not limited to, primary and secondary amides, primary and secondary amines and their corresponding protonated salts, thiols, alcohols, phosphonates, phosphates, ureas, or thioureas) and hydrogen bond acceptor groups (such as, but not limited to, ethers, thioethers, esters, tertiary amides, alkyl or aryl phosphonates and phosphates or tertiary amines). Aromatic amino acids encoded by a gene include phenylalanine and tyrosine.
A heteroaromatic amino acid residue refers to a hydrophobic amino acid residue having a side chain with at least one ring with a conjugated pi-electron system including at least one heteroatom, such as, but not limited to O, S and N (depending on the R for substituent)77General definition of (ii). In addition, such residues may contain hydrogen bond donor groups (such as, but not limited to, primary and secondary amides, primary and secondary amines and their corresponding protonated salts, thiols, alcohols, phosphonates, phosphates, ureas, or thioureas) and hydrogen bond acceptor groups (such as, but not limited to, ethers, thioethers, esters, tertiary amides, alkyl or aryl phosphonates and phosphates or tertiary amines). Gene-encoded heteroaromatic amino acidsIncluding tryptophan and histidine.
Group E comprises amino acids having side chains with polar cations, amido groups, and urea-derived residues (as per for substituent R)74General definition of (ii). Polar cations refer to basic side chains that are protonated at physiological pH. The polar cationic amino acids encoded by the gene include arginine, lysine and histidine. Citrulline is an example of a urea-derived amino acid residue.
Group F comprises amino acids having a side chain with a polar uncharged or anionic residue (as for substituent R)84General definition of (ii). Polar uncharged or anionic residues refer to hydrophilic side chains which are uncharged and anionic (carboxylic acids included) respectively at physiological pH, but which are not repelled by aqueous solutions. Typically, such side chains contain hydrogen bond donor groups such as, but not limited to, primary and secondary amides, carboxylic acids and esters, primary and secondary amines, thiols, alcohols, phosphonates, phosphates, ureas, or thioureas. These groups can form a hydrogen bonding network with water molecules. In addition, they may also contain hydrogen bond acceptor groups such as, but not limited to, ethers, thioethers, esters, tertiary amides, carboxylic acids and esters (salts) of carboxylic acids, alkyl or aryl phosphonates and phosphates or tertiary amines. The polar uncharged amino acids encoded by the gene include asparagine, cysteine, glutamine, serine and threonine, and also include aspartic acid and glutamic acid.
The group H comprises side chains which are preferably (L) -amino acids in opposite positions in the beta-chain region, which may form inter-chain bonds. The most well known bond is the disulfide bond formed by cysteine and homo-cysteine located opposite the β -chain. Various methods are known for disulfide bond formation, including J.P.Tam et al Synthesis 1979, 955-957; stewart et al, Solidphase Peptide Synthesis,2d Ed., Pierce Chemical Company, III., 1984; ahmed et al J.biol.chem.1975,250, 8477-8482; and those described by Pennington et al, Peptides, page 164-166, Giralt and Andreu, eds., ESCOM Leiden, the Netherlands, 1990. Most advantageously, for the scope of the present invention, a disulfide bond can be made using an acetamidomethyl (Acm) -protecting group for cysteine. A well established interchain bond consists in linking ornithine and lysine, respectively, to glutamic and aspartic acid residues located at opposite beta-strand positions through the formation of an amide bond. The preferred protecting group is allyloxycarbonyl (Alloc) for the side chain amino groups of ornithine and lysine and allyl ester for aspartic acid and glutamic acid. Finally, interchain linkages may also be established by linking the amino groups of lysine and ornithine in opposite β -strand positions with reagents such as N, N-carbonylimidazole to form cyclic ureas.
As previously described, the positions for the interchain bonds are positions P2 and 10 taken together. Such interchain linkages are known to stabilize the β -hairpin conformation and thus constitute important structural elements for the design of β -hairpin mimetics.

Particularly preferred β -peptide mimetics of the invention include those disclosed in examples 5, 19, 20, 22, 23, 38, 39, 40 and 75 as cathepsin G inhibitors; those disclosed as elastase inhibitors in examples 91, 121, 153, 154, 155, 156, 157, 158, 159, 160, 161177 and 178; and those disclosed as tryptase inhibitors in examples 193, 194 and 195.
The methods of the invention can be advantageously practiced as a parallel array synthesis to generate a library of template-fixed β -hairpin peptidomimetics of formula I above. Such parallel syntheses allow large arrays (typically 24 to 192, preferably 96) of compounds of formula I to be obtained in high yields and with defined purity, minimizing the formation of dimer and polymer by-products. Thus, proper selection of the functionalized solid support (i.e., solid support plus linker molecule), template, and cyclization sites plays an important role.
Can be prepared from polystyrene cross-linked with preferably 1-5% divinylbenzene, polystyrene coated with polyethylene glycol spacers (spacers)R) And polyacrylamide resins are conveniently obtained as a functionalized solid support (see also Obrecht d; villalgordo, J. -M, "Solid-Supported Combinatorial and parallel Synthesis of Small-Molecular-Weight Compound Libraries", Tetrahedron organic chemistry Series, Vol.17, Pergamon, Elsevier Science, 1998).
The solid support may be functionalized by a linker, i.e. a bifunctional spacer molecule containing an anchor group at one end for attachment to the solid support and a selectively cleavable functional group at the other end for subsequent chemical transformation and cleavage procedures. For the purposes of the present invention, two types of linker are used:
type 1 linkers are designed to release the amide group under acidic conditions (Rink H, Tetrahedron Lett.1987,28, 3783-. This type of linker forms an amide of the amino acid carboxyl group; examples of resins functionalized by such linker structures include 4- [ ((((2, 4-dimethoxyphenyl) Fmoc-aminomethyl) phenoxyacetamido) aminomethyl ] PS resin, 4- [ (((2, 4-dimethoxyphenyl) Fmoc-aminomethyl) phenoxyacetamido) aminomethyl ] -4-methylbenzhydrylamine PS resin (Rink amide MBHA PS resin), and 4- [ ((((2, 4-dimethoxyphenyl) Fmoc-aminomethyl) phenoxyacetamido) aminomethyl ] benzhydrylamine PS-resin (Rink amide BHA PS resin). Preferably, the support is obtained from polystyrene cross-linked with most preferably 1-5% divinylbenzene and functionalized with a 4- (((2, 4-dimethoxyphenyl) Fmoc-aminomethyl) phenoxyacetamido) linker.
Type 2 linkers are designed to eventually release the carboxyl group under acidic conditions. This type of linker forms acid labile esters with the carboxyl group of amino acids, typically acid labile benzyl, benzhydryl and trityl esters; examples of such linker structures include 2-methoxy-4-hydroxymethylphenoxy (Sasrin)RLinker), 4- (2, 4-dimethoxyphenyl-hydroxymethyl) -phenoxy (Rink linker), 4- (4-hydroxymethyl-3-methoxyphenoxy) butyric acid (HMPB linker), trityl and 2-chlorotrityl. Preferably, the support is obtained from polystyrene cross-linked with most preferably 1-5% divinylbenzene, and functionalized with a 2-chlorotrityl linker.
When the process of the invention is carried out as a parallel array synthesis, it may be advantageously carried out as described below, but it will be immediately apparent to the skilled person how to vary these procedures when one wishes to synthesize a single compound of formula I as described above.
A large number of reaction vessels (generally 24 to 192, typically 96) equal to the total number of compounds to be synthesized by the parallel method are loaded with 25 to 1000mg, preferably 100mg, of a suitable functionalized solid support, preferably obtained from polystyrene cross-linked with 1 to 3% divinylbenzene, or from Tentagel resin.
Solvents to be used must swell the resin and include, but are not limited to, Dichloromethane (DCM), Dimethylformamide (DMF), N-methylpyrrolidinone (NMP), dioxane, toluene, Tetrahydrofuran (THF), ethanol (EtOH), Trifluoroethanol (TFE), isopropanol, and the like. Solvent mixtures containing at least one component polar solvent (e.g., 20% TFE/DCM, 35% THF/NMP) are advantageous for ensuring and dissolving high reactivity and solvation of the peptide chain bound to the resin (Fields, g.b., Fields, c.g., j.am. chem. soc.1991,113, 4202-4207).
Considerable progress has been made in the synthesis of protected peptide fragments with the development of various linkers that release a C-terminal carboxylic acid group under mildly acidic conditions and do not affect the acid labile groups that protect functional groups in the side chains. 2-methoxy-4-hydroxybenzyl alcohol-derived linker (Sasrin)RThe linker, Mergler et al, Tetrahedron Lett.1988,294005-4008) was cleavable with diluted trifluoroacetic acid (0.5-1% TFA in DCM), and was stable to Fmoc deprotection conditions during peptide synthesis, with additional protecting groups based on Boc/tBu being compatible with this protection scheme. Other linkers suitable for use in the methods of the invention include: super acid-labile 4- (2, 4-dimethoxyphenyl-hydroxymethyl) -phenoxy linker (Rink linker, Rink, h.tetrahedron lett.1987,28, 3787-sec 3790) where removal of the peptide requires 10% acetic acid in DCM or 0.2% trifluoroacetic acid in DCM; 4- (4-hydroxymethyl-3-methoxyphenoxy) butanoic acid derived linker (HMPB-linker,&riniker, Peptides1991,1990131) which can also be cleaved by 1% TFA/DCM to generate peptide fragments containing all acid labile side chain protecting groups; and also, a 2-chlorotrityl chloride linker (Barlos et al, Tetrahedron Lett.1989,30, 3943-.
Suitable protecting groups for amino acids and their residues, respectively, are, for example:
for amino groups (as present, e.g. also in lysine side chains)
For carboxyl groups (if present, for example also in the aspartic and glutamic acid side chains), by conversion into esters with components of alcohols
For guanidino groups (as present, e.g. in arginine side chains)
For hydroxy groups (as present, e.g. in threonine and serine side chains)
tBu tert-butyl
Bn benzyl group
Trt trityl radical
And for mercapto groups (as present, e.g. in cysteine side chains)
Preferably, 9-fluorenylmethyloxycarbonyl (Fmoc) -protected amino acid derivatives are used as building blocks for the construction of template-fixed beta-hairpin loop mimetics of formula I. For deprotection, i.e. cleavage of the Fmoc group, 20% piperidine in DMF or 2% DBU/2% piperidine in DMF may be used.
The amount of reactant (i.e., amino acid derivative) is typically 1 to 20 equivalents based on milliequivalents (meq/g) of functionalized solid support per gram of loading initially weighed into the reaction tube (typically 0.1 to 2.85meq/g for polystyrene resins). Additional equivalents of reactants may be used, if desired, to drive the reaction to completion in a reasonable time. The reaction cuvette was reinserted into the storage section (reservoir block) in combination with the tube rack section (holder block) and manifold (maniffold), and the device was secured together. The gas flow through the manifold is initialized to provide a controlled environment, such as nitrogen, argon, air, etc. The gas stream may also be heated or cooled before flowing through the manifold. Heating or cooling of the reaction well is performed by heating the reaction table or cooling with isopropyl alcohol/dry ice or the like to cause the desired synthesis reaction to occur. Agitation is achieved by shaking or magnetic stirring (in a reaction tube). Preferred workstations, but not limited to, are Labsource's Combi-chem workstation and the MultiSyn Tech's-Syro synthesizer.
Amide bond formation requires activation of the alpha-carboxyl group for the acylation step. When passing through the usual carbodiimides, e.g. dicyclohexylcarbodiimide (DCC, Sheehan)&When Hess, J.Am.chem.Soc.1955,77,1067-1068) or diisopropylcarbodiimide (DIC, Saratakis et al biochem.Biophys.Res.Commun.1976,73,336-342) are subjected to such activation, dicyclohexylurea and diisopropylurea, respectively, are insoluble and soluble in the solvents conventionally used. In one variation of the carbodiimide process, a process involving 1-hydroxybenzotriazole (HOBt,&geiger, chem. Ber 1970,103,788-798) as an additive to the coupling mixture. HOBt prevents dehydration, inhibits racemization of activated amino acids, and acts as a catalyst to advance slow coupling reactions. Certain phosphorus reagents have been tried as direct coupling reagents, such as benzotriazol-1-yl-oxy-tris- (dimethylamino) -phosphonium hexafluorophosphate (BOP, Castro et al, Tetrahedron Lett.1975,14, 1219; Synthesis,1976,751-752) or benzotriazol-1-yl-oxy-tris-pyrrolidinyl-phosphonium hexafluorophosphate (Py-BOP, Coste et al, TetraDron Lett.1990,31, 205-; these phosphorus reagents are also suitable for in situ formation of HOBt esters with protected amino acid derivatives. More recently, Diphenoxyphosphorylazide (DPPA) or O- (7-aza-benzotriazol-1-yl) -N, N, N ', N' -tetramethyluronium tetrafluoroborate (TATU) or O- (7-aza-benzotriazol-1-yl) -N, N, N ', N' -tetramethyluronium Hexafluorophosphate (HATU)/7-aza-1-hydroxybenzotriazole (HOAt, Carpino et al, Tetrahedron Lett.1994,35, 2279-.
Since it is necessary to perform a near quantitative coupling reaction, experimental evidence of reaction completion is required. Ninhydrin tests (Kaiser et al, anal. biochemistry 1970,34,595) can be performed quickly and easily after each coupling step, where a positive colorimetric reaction against an aliquot of the resin-bound peptide quantitatively indicates the presence of a primary amine. The Fmoc chemistry method allows spectrophotometric detection of Fmoc chromophores when released with bases (Meienhofer et al, int.J. peptide Protein Res.1979,13, 35-42).
The resin bound intermediate in each reaction tube is washed free of excess residual reagents, solvents and by-products by repeated exposure to neat solvent by either:
1) loading a solvent (preferably, 5ml) into the reaction wells, immersing the reaction tubes and the tube rack components and manifold, agitating for 5 to 300 minutes, preferably, 15 minutes, and draining by gravity, followed by draining the solvent by applying air pressure through the manifold inlet (while closing the outlet);
2) the manifold is removed from the tube rack assembly, an aliquot (preferably 5ml) of solvent is dispersed through the top of the reaction tube, and drained by gravity through a filter into a receiving container (e.g., a tube or vial).
The above two washing procedures are repeated up to about 50 times (preferably, about 10 times), and the efficiency of the removal of the reagents, solvents and by-products is monitored by TLC, GC or the like or by observing the washings.
For each successive conversion, the procedure described above for reacting the resin bound compound with the reagent in the reaction well followed by removal of excess reagent, by-products and solvent is repeated until the final resin bound, fully protected linear peptide is obtained.
Prior to dissociation of such fully protected linear peptides from the solid support, one or more protected functional groups present in the molecule may be selectively deprotected, if desired, and the reactive groups released thereby suitably replaced. To achieve this effect, the functional group to be treated must initially be protected with a protecting group which can be selectively removed and which does not interfere with the remaining protecting groups present. Alloc (allyloxycarbonyl) is selectively removed (e.g., via CH)2Cl2Phenyl silane and Pd deg.) and does not affect the remaining protecting groups (e.g., Fmoc) present in the molecule. The reactive groups thus released may then be treated with a reagent suitable for introducing the desired substituent. Thus, for example, an amino group can be acylated by an acylating agent corresponding to the acyl substituent to be introduced. To form the pegylated amino acid, e.g., IPegK or SPegK, preferably 5 equivalents of HATU (N- [ (dimethylamino) -1H-1,2, 3-triazolo [4,5-b ] hexafluorophosphate in dry DMF]Pyridin-1-ylmethylene]-N-methylmethanamine N-oxide) and a solution of 10 equivalents of DIPEA (diisopropylethylamine) in anhydrous DMF, and, respectively, 5 equivalents of 2- [2- (2-methoxyethoxy) ethoxy ] ethoxy]Acetic acid (lPeg) and 2- (2-methoxyethoxy) acetic acid (sPeg) were applied to the liberated amino group of the appropriate amino acid side chain for 3 hours. After this time the resin was filtered and washed, the procedure was repeated with a fresh solution of the reagents for another 3 hours.
Prior to dissociation of the fully protected linear peptide from the solid support, interchain linkages may also be formed between the side chains of the appropriate amino acid residues at positions 2 and 10, if desired.
Interchain bonds and their formation have been discussed above in connection with the explanations for the group of the H type, which may be, for example, a disulfide bond formed between cysteine and homocysteine residues at opposite positions of the β -chain, or a lactam bridge formed by glutamic and aspartic acid residues linked to ornithine and lysine residues, respectively, at opposite β -chain positions, or a glutamic acid residue linked to a2, 4-diaminobutyric acid residue, via an amide bond. The formation of such interchain bonds can be accomplished by methods well known in the art.
To form disulfide bonds, preferably 10 equivalents of iodine solution is applied to DMF, or to CH2Cl21.5 hours in the/MeOH mixture, after filtration of the iodine solution, repeated for another 3 hours with fresh iodine solution, or else 10 equivalents of iodine solution were applied to the mixture of DMSO and acetic acid solution (with 5% NaHCO)3Buffered to pH 5-6) for 4 hours, or applied by stirring for 24 hours to water adjusted to pH 8 with ammonium hydroxide solution, or to ammonium acetate buffer adjusted to pH 8 in the presence of air, or to NMP and tri-n-butylphosphine (preferably, 50 equivalents).
Dissociation of the fully protected linear peptide from the solid support is achieved by dipping the reaction tube and tube rack components and manifold into a reaction well containing a lysis reagent solution (preferably 3 to 5 ml). Gas flow, temperature control, agitation, and reaction monitoring are performed as described above and as needed to achieve dissociation reactions. The reaction tubes, as well as the tube holder assembly and manifold, are removed from the storage section, lifted above the solution level but below the upper edge of the reaction wells, and air pressure is applied via the manifold inlet (while the outlet is closed) to efficiently discharge the final product solution into the storage wells. The remaining resin in the reaction tube is then washed 2 to 5 times with 3 to 5ml of a suitable solvent as described above to extract (wash out) as much of the cleavage product as possible. The product solutions thus obtained were combined and carefully carried out to avoid cross-mixing. The various solutions/extracts are then manipulated as required to isolate the final compound. Typical operations include, but are not limited to: evaporation, concentration, liquid/liquid extraction, acidification, basification, neutralization or other reactions in solution.
The solution containing the fully protected linear peptide derivative which has been cleaved from the solid support and neutralized with a base is subjected to evaporation. The cyclization is then carried out in solution using solvents such as DCM, DMF, dioxane, THF, etc. A variety of coupling reagents as previously mentioned can be used for the cyclization. The cyclization is continued for about 6 to 48 hours, preferably about 16 hours. The progress of the reaction is followed, for example, by RP-HPLC (reverse phase high performance liquid chromatography). The solvent is then removed by evaporation, the fully protected cyclic peptide derivative is dissolved in a water-immiscible solvent (e.g. DCM) and the solution is extracted with water or a mixture of water-miscible solvents to remove any excess coupling reagent.
Finally, with 95% TFA, 2.5% H2O, 2.5% TIS or other combinations of scavengers to effect cleavage of the protecting group. The cleavage reaction time is usually 30 minutes to 12 hours, preferably, about 2.5 hours. The volatiles were evaporated to dryness, the crude peptide was dissolved in 20% AcOH in water and extracted with isopropyl ether or other solvent suitable for this. The aqueous layer was collected and evaporated to dryness to obtain the fully deprotected cyclic peptide derivative of formula I as the final product.
Alternatively, dissociation from the solid support, cyclization and complete deprotection of the fully protected peptide can be achieved manually in glass containers.
Depending on its purity, the peptide derivative can be used directly in the biological assay, or it must be further purified, for example by preparative HPLC.
As mentioned before, the fully deprotected product of formula I thus obtained may then be converted into a pharmaceutically acceptable salt, or a pharmaceutically acceptable or unacceptable salt thus obtained may be converted into the corresponding free compound of formula I, or into a different, pharmaceutically acceptable salt, if desired. Any of these operations may be performed by methods well known in the art.

The β -hairpin peptidomimetics of the invention are useful in a wide range of applications where inflammatory or pulmonary diseases or infections or immune diseases or cardiovascular diseases or neurodegenerative diseases are mediated or caused by serine protease activity or where cancer is mediated or caused by serine protease activity. For the control or prevention of a given condition or disease that can be treated with a protease inhibitor, the β -hairpin peptidomimetic can be administered per se or as a suitable formulation together with carriers, diluents or excipients well known in the art.
When β -hairpin peptidomimetics are used to treat or prevent emphysema, rheumatoid arthritis, osteoarthritis, arteriosclerosis, psoriasis, cystic fibrosis, multiple sclerosis, adult respiratory distress syndrome, pancreatitis, asthma, allergic rhinitis, inflammatory skin diseases, post-angioplasty restenosis, cardiac hypertrophy, heart failure, or cancer (such as, but not limited to, breast cancer or cancers associated with angiogenesis or metastasis), the β -hairpin peptidomimetics may be administered alone, as a mixture of multiple β -hairpin peptidomimetics, in combination with other anti-inflammatory or antimicrobial or anti-cancer agents, and/or in combination with other pharmaceutically active agents. The β -hairpin peptidomimetics can be administered as such or as a pharmaceutical composition.
Pharmaceutical compositions comprising the β -hairpin peptidomimetics of the invention may be produced by conventional mixing, dissolving, granulating, manufacturing coated tablets, finely grinding, emulsifying, encapsulating, entrapping (entrap) or lyophilizing processes. Pharmaceutical compositions may be formulated by conventional means using one or more physiologically acceptable carriers, diluents, excipients or adjuvants which facilitate processing of the active β -hairpin peptidomimetic into a pharmaceutically acceptable formulation. The appropriate formulation depends on the method of administration selected.
For topical administration, the beta-hairpin peptidomimetics of the present invention can be formulated as solutions, gels, ointments, creams, suspensions, and the like, as is well known in the art.
Systemic formulations include those designed for administration by injection (e.g., subcutaneous, intravenous, intramuscular, intrathecal, or intraperitoneal injection), as well as those designed for transdermal, transmucosal, oral, or pulmonary administration.
For injection, the β -hairpin peptidomimetics of the invention can be formulated in a suitable solution, preferably in a physiologically compatible buffer, for example, a Hink's solution, ringer's solution or physiological saline buffer. The solution may contain formulating substances such as suspending, stabilizing and/or dispersing agents. Alternatively, the β -hairpin peptidomimetics of the invention may be in powder form for combination with a suitable vehicle (e.g., sterilized pyrogen-free water) prior to use.
For transmucosal administration, penetrants appropriate to the barrier to be permeated are used in the formulation, as is known in the art.
For oral administration, the β -hairpin peptidomimetics of the invention can be readily formulated by combining them with pharmaceutically acceptable carriers known in the art. Such carriers enable the beta-hairpin peptidomimetics of the invention to be formulated as tablets, pills, dragees, capsules, liquids, gels, syrups, slurries, suspensions and the like, for oral formulation by a patient to be treated. For oral formulations (e.g., powders, capsules, and tablets), suitable excipients include fillers (e.g., sugars such as lactose, sucrose, mannitol, and sorbitol; cellulose preparations such as corn starch, wheat starch, rice starch, potato starch, gelatin, tragacanth, methyl cellulose, hydroxypropylmethyl cellulose, sodium carboxymethyl cellulose, and/or polyvinylpyrrolidone (PVP)), granulating agents, and binding agents. If desired, disintegrating agents can be added, for example crosslinked polyvinylpyrrolidone, agar or alginic acid or a salt thereof (e.g. sodium alginate). The solid dosage forms may be sugar coated or enteric coated, if desired, using standard techniques.
For oral liquid preparations (e.g., suspensions, elixirs and solutions), suitable carriers, excipients or diluents include water, glycols, oils, alcohols and the like. In addition, flavoring agent, antiseptic, colorant, etc. can be added.
For buccal administration, the compositions may take the form of tablets, lozenges, and the like, which are generally formulated.
For administration by inhalation, the β -hairpin peptidomimetics of the present invention may be conveniently delivered in the form of an aerosol spray from a pressurized pack or a nebulizer, using a suitable propellant, e.g., dichlorodifluoromethane, trichlorofluoromethane, carbon dioxide or other suitable gas. In the case of a pressurized aerosol, the dosage unit may be determined by providing a valve to deliver a metered amount. Capsules and cartridges of, for example, gelatin for use in an inhaler or insufflator may be formulated containing a powder mix of the beta-hairpin peptidomimetic of the invention and a suitable powder base such as lactose or starch.
The compounds may also be formulated in rectal or vaginal compositions such as suppositories with suitable suppository bases such as cocoa butter or other glycerides.
In addition to the formulations described above, the β -hairpin peptidomimetics of the invention can also be formulated as depot preparations. Such long acting formulations may be administered by implantation (e.g. subcutaneously or intramuscularly) or by intramuscular injection. To produce such depot formulations, the β -hairpin peptidomimetics of the invention can be formulated with suitable polymeric or hydrophobic materials (e.g., as an emulsion in an acceptable oil) or ion exchange resins, or as sparingly soluble salts.
In addition, other drug delivery systems may be used, such as liposomes and emulsions, as are well known in the art. Certain organic solvents, such as dimethyl sulfoxide, may also be used. In addition, sustained release systems, such as semipermeable matrices of solid polymers containing the therapeutic agent, can be used to deliver the β -hairpin peptidomimetics of the invention. A variety of sustained release materials have been identified and are well known to those skilled in the art. Sustained release capsules may release compounds for weeks up to over 100 days, depending on their chemical nature. Depending on the chemical nature and biological stability of the therapeutic agent, additional strategies may be used for protein stabilization.
Because the β -hairpin peptidomimetics of the invention may contain charged residues, they may be included as such in any of the above formulations, or as a pharmaceutically acceptable salt. The solubility of pharmaceutically acceptable salts in aqueous or other protic solvents tends to be greater than that of the corresponding free forms.
The β -hairpin peptidomimetics of the invention or compositions thereof will generally be used in an amount effective to achieve the intended purpose. It will be appreciated that the amount used will depend on the particular application.
For topical administration to treat or prevent a disease treatable with a β -hairpin mimetic, a therapeutically effective dose can be determined using, for example, the in vitro assay provided in the examples. Treatment may be applied when the disease is visible or even when it is not yet visible. One of ordinary skill in the art will be able to determine, without undue experimentation, a therapeutically effective amount for treating a localized disease.
For systemic administration, the therapeutically effective amount can be estimated initially from in vitro tests. For example, the dose can be formulated in animal models to achieve a circulating β -hairpin peptidomimetic concentration range that includes the IC determined in cell culture50. Such information can be used to more accurately determine effective dosages in humans.
Initial dosages can be determined from in vivo data, such as animal models, using techniques well known in the art. One of ordinary skill in the art can readily optimize administration to humans based on animal data.
The dosage for use as a serpin can be individually adjusted to provide plasma levels of the beta-hairpin peptidomimetics of the invention sufficient to maintain a therapeutic effect. Therapeutically effective serum levels can be obtained by administering multiple doses per day.
In the case of local administration or selective absorption, the effective local concentration of the β -hairpin peptidomimetics of the invention may be independent of the plasma concentration. One of ordinary skill in the art will be able to optimize therapeutically effective topical dosages without undue experimentation.
The amount of β -hairpin peptidomimetic administered will, of course, depend on the subject being treated, the weight of the subject, the severity of the patient, the mode of administration, and the judgment of the prescribing physician.
Generally, a therapeutically effective dose of the beta-hairpin peptidomimetics described herein will provide therapeutic benefit without causing substantial toxicity.
Toxicity of the β -hairpin peptidomimetics of the invention can be determined by standard pharmaceutical procedures in cell cultures or experimental animals, e.g., by determining LD50(dose leading to 50% death in the population) or LD100(dose that resulted in 100% mortality of the population). The dose ratio between toxic and therapeutic effects is the therapeutic index. Compounds that exhibit high therapeutic indices are preferred. The data obtained from these cell culture assays and animal studies can be used to formulate dosage ranges that are non-toxic for use in humans. The dosage of the β -hairpin peptidomimetics of the invention is preferably in the range of circulating concentrations that include an effective dose with little or no toxicity. The dosage may vary within this range depending upon the dosage form employed and the route of administration utilized. The exact formulation, route of administration, and dosage can be selected by the individual physician taking into account the patient's condition.

Pharmacokinetic evaluation
Using software PK solution 2.0TM(Summit Research Service, Montrose, CO 81401USA), PK analysis was performed on the collected data (typically n ═ 2 or 3). The area under the curve AUC was calculated by linear trapezoidal law. The AUC(t-∞)Estimated as Ct/b (b: elimination rate constant). AUC(t-∞)Is AUC(0-t)And AUC(t-∞)The sum of (1). The elimination half-life is calculated by linear regression over at least three data points of the elimination period. By a correlation coefficient (r)2) To evaluate the time interval chosen for half-life determination, the correlation coefficient should be at least greater than 0.85 and most preferably greater than 0.96. In the case of intravenous administration, t is determined by extrapolating the curve from the first two time pointsZeroThe initial concentration of (c). Finally, by AUC after intraperitoneal administration normalized to intravenous administration(0-∞)In contrast, bioavailability after intraperitoneal administration was calculated.
