The present invention is directed to compounds represented by the following structural formula, and pharmaceutically acceptable salts, solvates and hydrates thereof, R1 is a substituted or unsubstituted group selected from C-Calkyl, aryl-С-alkyl, heteroaryl-C-alkyl, С-Сcycloalkylaryl-C-alkyl or phenyl. W is O or is H or a substituted or unsubstituted group selected from C-Calkyl, С-Сcycloalkyl and heteroaryl. X is аС-Сalkylene linker wherein one carbon atom of the linker may be replaced with O, NH or S. Y is C, O, S, NH or a single bond. Furthermore, E is (CH)COOH, wherein n is 0, 1, 2 or 3, or C(R3)(R4)A, wherein A is an acidic functional group such as carboxyl, carboxamide substituted or unsubstituted sulfonamide, or substituted or unsubstituted tetrazole. R3 is H, saturated or unsaturated C-Calkyl, C-Calkoxy. Additionally, R4 is H, halo, a substituted or unsubstituted group selected from C-Calkyl, C-Calkoxy, С-Сcycloalkyl, arylC-Calkyl and phenyl, or R3 and R4 are combined to form аС-С, cycloalkyl. |
