Diaminomethylidene derivatives
First Claim
1. A diaminomethylidene derivative represented by formula (I) ##STR44## wherein R1 is a hydrogen atom, a C1 -C6 alkyl group, a C3 -C6 cycloalkyl group, a C3 -C6 cycloalkyl C1 -C1 alkyl group, an aryl group or an aryl C1 -C4 alkyl group, in which the aryl moiety of the aryl group or aryl C1 -C4 alkyl group may be optionally substituted with a halogen atom, a C1 -C6 alkyl group, a halo C1 -C6 alkyl group, a C1 -C6 alkoxy group, a C1 -C6 alkoxycarbonyl group, a phenyl group or an amino group;
- X is O, S, CHNO2, C(COOR4)2, C(COOR4)CN or C(CN)2, in which R4 is a C1 -C6 alkyl group, a C3 -C6 cycloalkyl group, an aryl group, or an aryl C1 -C4 alkyl group;
R2 is a group of the following general formulae (II)-(III);
##STR45## wherein R5 is a C1 -C6 alkyl group, an aryl C1 -C4 alkyl group, or an aryloxy C2 -C6 alkyl group, or in which the aryl moiety of the said groups may be optionally substituted with a halogen atom, a C1 -C6 alkyl group, a halo C1 -C6 alkyl group, a C1 -C6 alkoxy group, a C1 -C6 alkoxycarbonyl group, a phenyl group or an amino group,Z1 and Z2 are O;
R3 is a hydrogen atom, a C1 -C6 alkyl group or a C1 -C6 alkoxy C2 -C6 alkyl group;
provided that there is excluded a compound wherein R1 is an aryl group, X is O, and R2 is a group of formula (II) wherein R5 is a C1 -C2 alkyl group or a pharmacologically acceptable salt thereof.
