Patent ID: 8008302

Claim:
A N-hydroxyamide according to Formula (I), wherein: A is N; R 1 is selected from C 1 -C 6 alkyl, C 3 -C 8 -cycloalkyl, aryl, pyridinyl, pyrazinyl, thiadiazolyl, pyrimidinyl, oxadiazolyl, quinolinyl, thienyl, benzofuranyl, amino and alkoxy; R 2 is selected from H, C 1 -C 6 alkyl, C 2 -C 6 alkenyl, C 2 -C 6 alkynyl, C 3 -C 8 -cycloalkyl, and aryl; R 3 is selected from H, C 1 -C 6 alkyl, C 2 -C 6 alkenyl and C 2 -C 6 alkynyl; R 4 , R 5 , R 6 and R 7 are independently selected from H, C 1 -C 6 alkyl, C 2 -C 6 alkenyl, C 2 -C 6 alkynyl; or R 4 and R 7 form together a —CH 2 — linkage; n is an integer selected from 1, 2, 3, 4, 5 and 6; wherein R 1 -R 7 may be substituted by from 1 to 5 substituents selected from the group consisting of C 1 -C 6 -alkyl, amino, halogen, carboxy, trihalomethyl, cyano, hydroxy, mercapto, and nitro; Carbons (2) and (3) are two chiral centers, wherein chiral center (2) has a configuration selected from “S” and “R” and wherein chiral center (3) has a “S” configuration as well as pharmaceutically acceptable salts thereof.
