| abstract |
The invention relates to novel products having formula (I), wherein: Y represents N, O, S, CHR3 or =CR3; the dotted lines represent a single or double bond; R and R1 represent, in particular, H, Hal, OH, alkyl, alkoxy, cyano, NO2, NR4R5, trifluoromethyl, trifluoromethoxy, aryl, heteroaryl, -S(O)n-NR4R5, whereby n represents 0 to 2, acyl, -NH-CO-alkyl or -NH-CO-NH-phenyl; R3 represents H, Hal, alkyl, cyano, NO2, NR4R5, trifluoromethyl or aryl; R2 represents R4, OR4, SR4 or NR4R5; and R4 represents H, alkyl, cycloalkyl or aryl. According to the invention, either R4 and R5 are selected from among the values of R4, or R4 and R5, together with N, form a heterocyclic radical which can contain N, 0 and S, all of said radicals being optionally substituted. Moreover, the aforementioned products take all of the isomeric and salt forms for use as medicaments. |
