Patent ID: 8017646

Claim:
A compound of formula (I): with R 1 and R 2 taken together with the nitrogen atom to which they are attached, form a saturated nitrogen-containing pyrrolidine ring: m being 4, each R a , R b is independently identical or different, and R a represent a hydrogen and R b represents a hydrogen or a C 1 -C 4 alkyl, wherein A is a saturated linear C2-C4 alkylene; chain B is chosen from the groups selected within C 3 -C 4 linear alkylene or C 3 -C 4 linear alkenylene; R 5 is chosen from a fluor atom, —O(C 1 -C 4 )Alkyl, and each of R 3 , R 4 , R 6 , R 7 represents H, or R 4 and R 5 form together a saturated heterocycle fused with the phenyl group, and each of R 3 , R 6 , R 7 represents H; or their pharmaceutically acceptable salts, or their optical isomers, racemates, diastereomers or enantiomers.
