Patent ID: 7253162

Claim:
A compound selected from those of formula (I): wherein: R 1 represents hydrogen, halogen, or linear or branched (C 1 -C 6 )alkyl, R 1a represents hydrogen or linear or branched (C 1 -C 6 )alkyl, R 2 represents hydrogen, halogen, or hydroxy, A represents NR 4 , and R 3 and R 4 , together with the carbon and nitrogen atoms to which they are attached, form a ring wherein m represents 1, 2, or 3, X represents NR 6 R 7 , S(O) n R 8 , or OR′ 8 , or a heterocyclic group, wherein: R 6 represents hydrogen, linear or branched (C 1 -C 6 )alkyl, S(O) p R 9 , COR 9 , or P(O)OR 9 OR 10 , R 7 represents hydrogen, or linear or branched (C 1 -C 6 )alkyl, or R 6 and R 7 , together with the nitrogen atom carrying them, form a heterocyclic group, R 8 , R 9 and R 10 , which may be the same or different, represent hydrogen; linear or branched (C 1 -C 6 )alkyl optionally substituted by one or more halogen; aryl-(C 1 -C 6 )alkyl in which the alkyl moiety is linear or branched; or aryl, R′ 8 represents linear or branched (C 1 -C 6 )alkyl or linear or branched (C 1 -C 6 )acyl, n and p, which may be the same or different, represent 1 or 2, its enantiomers and diastereoisomers, and addition salts thereof with a pharmaceutically-acceptable acid or base.
