摘要:
Novel biphenyl derivatives of the general formula (I) in which R1, R1′, R1″, R2, R2′, R3 and n are as defined in claim 1, their stereoisomers and their physiologically acceptable salts or solvates are novel integrin inhibitors which preferentially inhibit the αvβ6 integrin receptor. The novel compounds can be used, in particular, as medicaments.

摘要:
The invention describes novel compounds of the formula I which are biologically active as ligands of integrin &agr;v&bgr;3 X—Y—Z—R1—CH2—R2(R4)—CH2—CO—R5 in which X, Y, Z, R1, R2, R4 and R5 are as defined in claim 1, and their physiologically acceptable salts and solvates.
摘要:
The invention relates to a pharmaceutical preparation [lacuna] cyclo(Arg-Gly-Asp-D-Phe-NMe-Val) and/or one of its physiologically acceptable salts and at least one chemotherapeutic agent and/or one of its physiologically acceptable salts and/or an angiogenesis inhibitor and/or one of its physiologically acceptable salts.
摘要:
The invention relates to novel cyclopeptides of the formula Icyclo-(nArg-nGly-nAsp-nD-nE) I,in whichD and E in each case independently of one another are Gly, Ala, .beta.-Ala, Asn, Asp, Asp(OR), Arg, Cha, Cys, Gln, Glu, His, Ile, Leu, Lys, Lys(Ac), Lys(AcNH.sub.2), Lys(AcSH), Met, Nal, Nle, Orn, Phe, 4-Hal-Phe, homo-Phe, Phg, Pro, Pya, Ser, Thr, Tia, Tic, Trp, Tyr or Val, which amino acid residues can also be derivatized,R is alkyl having 1-18 carbon atoms,Hal is F, Cl, Br, I,Ac is alkanoyl having 1-10 carbon atoms, aroyl having 7-11 carbon atoms or aralkanoyl having 8-12 carbon atoms,n denotes no substituent or an alkyl radical R, benzyl or an aralkyl radical having 7-18 carbon atoms on the alpha-amino function of the relevant amino acid residue,with the proviso that at least one amino acid residue has a substituent n and that, where residues of optically active amino acids and amino acid derivatives are involved, both the D and the L forms are included, and also their physiologically acceptable salts.These compounds act as integrin inhibitors and can be used in particular for the prophylaxis and treatment of disorders of the circulation, angiogenic disorders, microbial infections and in tumor therapy.
摘要:
This invention relates to inhibition of αv integrins, especially αvβ3 and αvβ6 integrins, by specific antagonists, preferably non-peptidic antagonists, related compounds and compounds with comparable specificity, that downregulate fibrogenesis by inhibiting cell migration and production of pro-fibrogenic molecules (e.g., collagens, TIMP-1) and cytokines (e.g., CTGF) by activated hepatic stellate cells/myofibroblasts, activated epithelia and endothelia. These antagonists alone or in combination with other agents can effectively prevent, mitigate or even reverse development of advanced fibrosis, such as fibrosis/cirrhosis of the liver and fibrosis of other organs, such as lungs, kidneys, intestine, pancreas, skin and arteries.
摘要:
The invention concerns cyclopeptides of formula (I): Cyclo-(Arg-Gly-Asp-X-Y) in which X is Cha, Nal, Phe, 2-R.sup.1 -Phe, 3-R.sup.1 -Phe, 4-R.sup.1 -Phe, homo-Phe, Phg, Thi, Trp, Tyr or derivatives of Tyr, whereby the OH group can be etherified by alkyl groups containing 1-18 C-atoms and the amino-acid groups given can also be derivatives, R.sup.1 is NH.sub.2, NO.sub.2, I Br, Cl, F, alkyl with 1-18 C-atoms, Ar, Ar--O or.sup.3 H, Y is Gly in which the .alpha. N-atom may be substituted by R.sup.2 and/or the .alpha. C-atom may be substituted by R.sup.3 and/or R.sup.4, with the provision that Gly has at least one of the substituents specified, Ar is phenyl which may be substituted by one or two of groups NH.sub.2, NO.sub.2, I, Br, Cl, F, alkyl with 1-6 C-atoms or .sup.3 H, R.sup.2, R.sup.3 or R.sup.4, independently of each other, are alkyl with 1-18 C-atoms or R.sup.2 and R.sup.3 or R.sup.3 and R.sup.4 together in each case are a branched or unbranched alklyene chain with 3 to 18 C-atoms so that either the .alpha. N-atom or the .alpha. C-atom together with the alkylene chain, or the .alpha. C-atom alone, forms a ring with alkylene chain, whereby, when optically active amino-acid or amino-acid-derivative groups are involved, both the D- and the L-form are included, plus derivatives, in particular the .beta.-ester of aspartic acid or N-guanidine acyl derivatives of arginine or prodrug as well as their physiologically acceptable salts. These compounds act as integrin inhibitors and may be used particularly for the prophylaxis and treatment of circulatory and angiogenic conditions and microbial infections as well as in tumor therapy.
摘要:
The invention relates to novel cyclopeptides of the formula I cyclo-(Arg-A-Asp-R.sup.1 -R.sup.2) I in which A, R.sup.1 and R.sup.2 have the meaning given in claim 1, and their salts.
