Claim:
A compound of the formula I in which X is CH 2 , O or NH; Y is CH 2 , O or NH; R1, R2, R3 are each independently of one another OH, COOH; CONH 2 , CONH(C 1 –C 16 )alkyl, CONH(C 1 –C 16 )alkenyl, CONH(C 1 –C 6 )alkyl-phenyl, where phenyl may be mono- to trisubstituted by O—(C 1 –C 10 )alkyl or O—(C 1 –C 10 )alkyl-phenyl, CONH(C 1 –C 6 )alkyl-benzimidazole, where the benzimidazole ring may be mono- to trisubstituted by S-phenyl, wherein the S-phenyl may be mono- to trisubstituted by F, Cl, Br, I, OH, CF 3 , NO 2 , CN, OCF 3 , O—(C 1 –C 10 )alkyl, NH 2 , NH(C 1 –C 6 )alkyl, COOH, COO(C 1 –C 6 )alkyl, CONH 2 ; (C 2 –C 6 )alkenyl, (C 2 –C 6 )alkynyl, (C 1 –C 6 )alkyl-COOH, (C 1 –C 6 )alkyl-aryl, where aryl may be phenyl, naphthyl, biphenyl, thienyl or pyridyl and the aryl moiety may in each case be mono- to trisubstituted by F, Cl, Br, I, OH, CF 3 , NO 2 , CN, OCF 3 , O—(C 1 –C 10 )alkyl, NH 2 , NH(C 1 –C 6 )alkyl, COOH, COO(C 1 –C 6 )alkyl, CONH 2 ; Phenyl, biphenyl, 1- or 2-naphthyl, 2-,3- or 4-pyridyl, 2- or 3-furanyl or 2- or 3-thienyl, where the phenyl, biphenyl, naphthyl, pyridyl, furanyl or thienyl rings may in each case be mono- to trisubstituted by F, Cl, Br, I, OH, CF 3 , NO 2 , CN, OCF 3 , O—(C 1 –C 10 )alkyl, NH 2 , NH(C 1 –C 6 )alkyl, COOH, COO(C 1 –C 6 )alkyl, CONH 2 ; (C 3 –C 18 )cycloalkyl, where in the alkyl radicals one or more hydrogens may be replaced by fluorine or one hydrogen may be replaced by OH, (C 1 –C 6 )alkyl-phenyl or O—(C 1 –C 6 )alkyl-phenyl, NCO, NSO 3 —(C 1 –C 10 )alkyl; or in each case two of the radicals R1 and R2 or R2 and R3 or R1 and R3 together form a fused aryl radical, where aryl may be phenyl, naphthyl, biphenyl, thienyl or pyridyl and the aryl moiety may in each case be mono- to trisubstituted by F, Cl, Br, I, OH, CF 3 , NO 2 , CN, OCF 3 , O—(C 1 –C 10 )alkyl, NH 2 , NH(C 1 –C 6 )alkyl, COOH, COO(C 1 –C 6 )alkyl, CONH 2 ; or its physiologically acceptable salts or prodrugs.
