Patent ID: 7632854

Claim:
A compound of formula (I) wherein R is, in position 5 or 6 of the indazole ring, a halogen atom or an optionally substituted group selected from straight or branched C 2 -C 6 alkenyl, C 2 -C 6 alkynyl, or aryl which is selected from phenyl, indanyl, biphenyl, α-or β-naphthyl, fluorenyl, 9,10-dihydroanthracenyl, pyridyl, pyrazinyl, pyrimidinyl, pyridazinyl, indolyl, imidazolyl, imidazopyridyl, 1,2-methylenedioxyphenyl, thiazolyl, isothiazolyl, pyrrolyl, pyrrolyl-phenyl, furyl, phenyl-furyl, benzotetrahydrofuranyl, oxazolyl, isoxazolyl, pyrazolyl, chromenyl, thienyl, benzothienyl, isoindolinyl, benzoimidazolyl, isoindolinyl-phenyl, quinolinyl, isoquinolinyl, 2,6-diphenyl-pyridyl, quinoxalinyl, pyrazinyl, phenyl-quinolinyl, benzofurazanyl, 1,2,3-triazolyl, 1-phenyl-1,2,3-triazolyl, pyran, pyrroline, or pyrazoline; R 1 is an optionally substituted group selected from —NHCOR′; R a and R b are, each independently, hydrogen or a straight or branched C 1 -C 6 alkyl group; R′ and R″ are, each independently, hydrogen or an optionally substituted group selected from straight or branched C 1 -C 6 alkyl, C 2 -C 6 alkenyl or alkynyl, C 3 -C 6 cycloalkyl or cycloalkyl C 1 -C 6 alkyl, aryl or aryl C 1 -C 6 alkyl wherein aryl is as above defined, or a 5or 6 membered heterocyclyl or heterocyclyl C 1 -C 6 alkyl; or, when taken together with the nitrogen atom to which they are attached, R′ and R″ may form an optionally substituted 4 to 7 membered heterocycle, optionally containing an additional heteroatom selected from S, O or N; or isomers, tautomers, and pharmaceutically acceptable salts thereof.
