摘要

A compound having the general formula (I) ** (See formula) ** in which X is a bond or a group -CR5R6, in which R5 and R6 are selected, independently of each other, from the group consisting of H; alkyl selected from the group CH3, C2H5, i-C3H7, n-C3H7, i-C4H9, n-C4H9, sec-C4H9 and tert-C4H9; alkenyl selected from C2H3, i-C3H5, n-C3H5, n-C4H7, i-C4H7, sec-C4H7; where, in all named alkyl and alkenyl groups, one or more H atoms are optionally substituted with one or more substituents independently selected from the group consisting of F, Cl, Br, I and CF3; or R5 and R6 are part of a ring, saturated or unsaturated, substituted or unsubstituted, of 3 to 6 C atoms, and which may contain in the ring one or more heteroatoms of the group N, S or O, and whose heteroatoms may be identical or different if more than one heteroatom is present; R1, R2, R3 and R4 are independently selected from the group consisting of H; F; Cl; Br; I; CN; OH; C (O) N (R7R8); S (O) 2R7; SO2N (R7R8); S (O) N (R7R8); N (R7) S (O) 2R8; N (R8) S (O) R8; S (O) 2R7; N (R7) S (O) 2N (R8R8a); SR7, N (R7R8); N (R7) C (O) R8; N (R7) C (O) N (R8R8a); N (R7) C (O) OR8, OC (O) N (R7R8); C (O) R7, substituted and unsubstituted C1-C4 alkyl and substituted and unsubstituted C1-C4 alkoxy, and wherein the substituents of both C1-C4 alkyl and C1-C4 alkoxy groups are selected from F, Cl , Br, I, CF3; R7, R8, R8a are independently selected from the group consisting of H; C1-C4 alkyl, heterocyclyl; and C3-7 cycloalkyl, wherein C1-C4 alkyl; the heterocyclyl and the C3-7 cycloalkyl are optionally substituted with one or more substituents independently selected from the group consisting of F, Cl, Br, I and CF3; Y is a carboxy-C (O) OH group or a substituted or unsubstituted tetrazole group; and / or a salt or ester thereof.
