<p>Novel dihydro-1,2 oxo-2 quinoxaline derivates corresponding to general formula (I) in which R represents a hydrogen or halogen atom; R1 represents a hydrogen atom or C1-C4 alkyl radical, linear or branched; R2 represents: a hydrogen atom, a C(O)R4 radical where R4 is C1-C4 alkyl group, linear or branched, a C(O)NHR4 radical where R5 is C1-C4 alkyl group linear or branched, or a phenyl group; A represents C1-C4 alkylene chain; R3 represents a hydrogen atom, C1-C4 alkyl radical, C3-C6 cycloalkyl radical, an alkynyl, nitril, hydroxyl, carboxamido, pyridyl, phenyl group or a phenyl substituted by a halogen atom, C1-C4 alkyl group, C1-C4 alkoxy group, or a nitro group; an alkenyl radical of formula (α) where R6, R7 can, independently of each other, be a hydrogen atom, C1-C4 alkyl group, a phenyl group, or an alkoxycarbonyl group; a radical of the formula -OC(O)R8, where R8 represents C1-C4 alkyl radical; a radical of the formula -OC(O)NHR9, where R9 represents C1-C4 alkyl radical, linear or branched, or a phenyl group; n can take values from 2 to 4, as well as the organic or mineral salts of said molecules which are therapeutically acceptable.</p> |
