Claim 1: A compound of the formula (1), wherein: Ring A is cycloalkanediyl (C3-8) or cycloalkenodiyl (C3-8), wherein in the cycloalkane- or cycloalkenodiyl rings one or more carbon atoms may be replaced by oxygen atoms; R1 and R2 independently of one another are H, (C1-6) alkyl, cycloalkyl (3-8) or aryl (C6-10); R3 is cycloalkyl (C3-6) or alkyl (C1-12), which are optionally substituted with aryl (C6-10), heteroaryl (C5-6) or cycloalkyl (C3-6), where aryl, heteroaryl or cycloalkyl by its part, they may be substituted with (C1-6) alkyl, (C1-6) alkoxy, Cl, Br, I, CO-(C1-6) alkyl, CO-O-(C1-6) alkyl, CO-NH- (C1-6) alkyl or CO-N ((C1-6) alkyl) 2; X is alkanediyl (C1-8), where in the alkanediyl group one or more carbon atoms can be replaced by oxygen atoms; Y1 is CO or a link; Y2 is NH, (C1-12) alkanediyl, where in the alkanediyl group one or more carbon atoms can be replaced by oxygen atoms; R4 is (C1-8) alkyl; R5 is H, (C1-6) alkyl; R6 is H; and its physiologically acceptable salts. |
