Patent ID: 8772279

Claim:
A compound of the formula (I): wherein: R 1 is —NR 3 R 4 or —OR 3 ; R 2 is a hydrogen atom or an optionally substituted group selected from straight or branched C 1 -C 6 alkyl, aryl, heteroaryl, aryl C 1 -C 6 alkyl and heteroaryl C 1 -C 6 alkyl; R 3 and R 4 , the same or different, are each independently hydrogen atom or an optionally substituted group selected from straight or branched C 1 -C 6 alkyl, C 2 -C 6 alkenyl, C 2 -C 6 alkynyl, C 3 -C 6 cycloalkyl, cycloalkyl C 1 -C 6 alkyl, heterocyclyl, heterocyclyl C 1 -C 6 alkyl, aryl, aryl C 1 -C 6 alkyl, heteroaryl and heteroaryl C 1 -C 6 alkyl, or R 3 and R 4 , taken together with the nitrogen atom to which they are bonded, may form an optionally substituted 3 to 7 membered heterocyclyl or heteroaryl ring, optionally containing one additional heteroatom or heteroatomic group selected from S, O, N and NH; or a pharmaceutically acceptable salt thereof, wherein the optionally substituted group of R 2 , R 3 and R 4 is substituted in any of its free positions by 1 to 6 groups, selected from the groups consisting of: halogen, nitro, oxo groups (═O), carboxy, cyano, C 1 -C 6 alkyl, polyfluorinated alkyl, C 2 -C 6 alkenyl, C 2 -C 6 alkynyl, C 3 -C 6 cycloalkyl, heterocyclyl, aryl, heteroaryl; amino groups and derivatives thereof; carbonylamino groups and derivatives thereof; hydroxy groups and derivatives thereof; carbonyl groups and derivatives thereof; and sulfurated derivatives, wherein when R 1 is —NR 3 R 4 , only one of R 3 and R 4 are hydrogen and when R 1 is —OR 3 , R 3 is not hydrogen.
