Patent ID: 8110571

Claim:
A compound of formula (I) wherein: A represents NH or S; R1 and R2, which may be identical or different, are chosen from a hydrogen atom, halogen atoms, and alkyl radicals optionally substituted with one or more halogen atoms; R3 represents a hydrogen atom or is chosen from the values of R1 and R2; it being understood that at least one from among R1, R2 and R3 does not represent hydrogen; R is NR4R5 in which R4 and R5 are such that one from among R4 and R5 is hydrogen or alkyl and the other from among R4 and R5 is alkyl substituted with one or more groups, which may be identical or different, chosen from hydroxyl, alkoxy and NR6R7, with R6 and R7, which may be identical or different, representing hydrogen or alkyl, or alternatively R6 and R7 form, with the nitrogen atom to which they are attached, a nitrogen containing heterocyclic optionally containing one or more other heteroatoms chosen from 0, S, N and NH, this heterocyclic, including the possible NH it contains, being optionally substituted; and all the alkyl and alkoxy groups of R containing from 1 to 4 carbon atoms; said heterocyclic which R6 and R7 may form with the nitrogen atom to which they are attached being optionally substituted with one or more radicals chosen from halogen atoms, hydroxyl, oxo, alkoxy, NH 2 ; NHalk, N(alk) 2 radicals and alkyl, CH 2 -heterocycloalkyl, CH 2 -phenyl and CO-phenyl radicals, such that in these latter radicals the alkyl, heterocycloalkyl and phenyl radicals are themselves optionally substituted with one or more radicals chosen from halogen atoms and hydroxyl, oxo, alkyl and alkoxy containing from 1 to 4 carbon atoms, NH 2 ; NHalk and N(alk) 2 radicals, and all the alkyl and alkoxy radicals of R1, R2 and R3 containing from 1 to 6 carbon atoms; or an inorganic or organic acid addition salt thereof, or an inorganic or organic base addition salt thereof.
