Composition corresponding to formula (I), in which R is a cycloalkyl, optionally substituted aryl, optionally substituted aryalkyl, optionally substituted heterocyclic radical, = R3, or NR1R2, or, in turn, R3 represents an alkyl radical and R1 and R2 are the same or different and representing H or an alkyl radical or else with the N atom to which they are linked, they form a pentagonal or hexagonal heterocyclic ring, provided however that R is not a pyridine ring, as well as the salts of these compounds with organic or inorganic acids, acceptable in pharmacy. |
