| abstract |
The invention concerns benzimidazole derivatives of general formula (I) wherein: X represents a nitrogen atom or a carbon atom, and when X represents a nitrogen atom: R3 represents a hydrogen atom or a C1-C4 alkyl group, or does not exist to produce compounds of formula (I) comprising a secondary or tertiary amine; R4 represents a hydrogen atom or a C1-C6 alkyl, C3-C7 cycloalkyl, C3-C7 heterocycloalkyl group optionally substituted, -(CH2)p-heteroaryl, heteroarylcarbonyl, phenylcarbonyl, C1-C6 alkylcarbonyl, -(CH2)pCOOR, phenylsulphonyl group optionally substituted; and when X represents a carbon atom: R3 represents a hydrogen atom or a -NR5R6, -N(R5)3+, -NHCOR7, -CONHR5, -COR7, -NHCONH¿2?, -OH or CH2OH group, R4 represents a hydrogen atom or a -(CH2)p-phenyl group optionally substituted, -(CH2)p-heteroaryl or-(CH2)tNR7R8 group. The invention is useful in therapeutics for preparing a medicine for preventing or treating disorders wherein the poly(ADP-ribose) polymerase is involved. |
