Abstract:
1. A compound of formula (I): wherein R1 and R2 taken together with the nitrogen atom to which they are attached, form a mono or bicyclic saturated nitrogen-containing ring of formula: with m=4 or 5, each Rb is independently identical or different, and Rb is a hydrogen or a C 1 -C 4 alkyl, or 2 Rb form together a bond so as to form a bicyclic ring, chosen from: R is chosen from: a) a pyridyl group, or a cycloalkyl, each optionally substituted with one or more of Halogen atom, C1-C4 alkyl, O—C1-C4 alkyl, OH, or NR3R4; and where the N atom within the pyridyl ring may be in the form of N-Oxide (N bicyclic aryl substituted with one or more of Halogen atom, C1-C4 alkyl, O—C1-C4 alkyl, OH, NR3R4, —C where alkyl, alkenyl or alkynyl is optionally substituted with a heterocycle, or NR3R4; wherein R3, R4 are independently hydrogen, a straight or branched C or their pharmaceutically acceptable salts, or their optical isomers, racemates, diastereomers or enantiomers.
