beta -PHENYLALANINE DERIVATIVES AS INTEGRIN ANTAGONISTS

摘要

The present invention relates to compounds of general formula (1), wherein R<4> is -SO2R<4'>, -COOR<4">, -COR<4'>, -CONR<4'>2 or -CSNR<4'>2; R<4'> is hydrogen, a substituted or unsubstituted alkyl or cycloalkyl residue, a substituted or unsubstituted aryl residue or a saturated or unsaturated, optionally substituted heterocyclic residue; R<4"> is a substituted or unsubstituted alkyl or cycloalkyl residue, a substituted or unsubstituted aryl residue or a saturated or unsaturated, optionally substituted heterocyclic residue; L is a sulphonamide, amide, ether, ester, keto, urea, thioether, sulphoxide or sulphone unit optionally extended by one or two methylene groups; and X is N, O or S; and their physiologically acceptable salts and stereoisomers. The present invention furthermore relates to a process for the preparation of the compounds of formula (1), a pharmaceutical composition containing at least one of these compounds, and the use of compounds of formula (1) for the production of a pharmaceutical composition having integrin-antagonistic action and in particular for the inhibition of angiogenesis and/or for the therapy and prophylaxis of cancer, osteolytic diseases such as osteoporosis, arteriosclerosis, restenosis and ophthalmic disorders.
