A pharmaceutically acceptable salt of a substituted 2-oxoalkyl-1-piperazin 2-one compound

Abstract

The invention relates to a compound of formula (I): wherein: ALK is a (CrC6)alkylene group; X1 et X2 are each independently one of the following groups: -CH=CH-, -CO-, -CONR-, NRCO-, -COO-, -OCO-, -OCONR-, -NRCOO-, -NRCONR'-, -NR-, -S(O)n (n=0,1 or 2) or-O-; R and R' are independently H or a (CrC6)alkyl group; i is an integer of from 1 to 40, preferably from 1 to 20, end more preferably from 1 to 10; j is an integer corresponding to 1 when X2 is CH-CH- and 2 when X2 is ndt -CH=CH-; Zb is a simple bond, -O- or -NH- and Rb is H or a (CrCgJalkyl, (C3-C7)cycloalkyl, aryl, heteroaryl or (C3-C7) heterocycloalkyl group ; orZb is a single bond and Rb is Hal.
