Patent ID: 7105535

Claim:
A compound which is an oxazolyl-pyrazole derivative represented by formula (I): wherein R represents a hydrogen atom; a straight or branched C 1 –C 8 alkyl group; a straight or branched C 2 –C 8 alkenyl group; an aryl or aryl C 1 –C 6 alkyl group; a saturated or unsaturated C 3 –C 6 cycloalkyl or cycloalkyloxy group optionally further condensed with 1 or 2 benzene rings; or it is an optionally benzocondensed 5 or 6 membered heterocyclic or heterocyclyl C 1 –C 6 alkyl group, having 1 or 2 heteroatoms selected among nitrogen, oxygen or sulfur; each of the above defined R groups being optionally further substituted by one or more groups selected from: i) halogen, nitro, cyano, hydroxy, oxo groups (═O); ii) straight or branched C 1 –C 6 alkyl, alkoxyalkyl or perfluorinated alkyl; iii) aryl or 5 or 6 membered heterocycles having 1 or 2 heteroatoms selected among nitrogen, oxygen or sulfur, optionally substituted by halogen, nitro, cyano, C 1 –C 6 alkyl or alkoxy; iv) straight or branched C 1 –C 6 alkoxy, alkoxyalkyloxy, arylalkyloxy or aryloxy optionally substituted by halogen, nitro, cyano, C 1 –C 6 alkyl or alkoxy; v) straight or branched C 1 –C 6 alkylthio or alkylsulphonyl, arylthio or arylsulphonyl; vi) C 3 –C 6 cycloalkyl; vii) amino, C 1 –C 6 alkylamino, dialkylamino or arylamino; viii) C 1 –C 6 alkylcarbonyl, alkyloxycarbonyl, alkylaminocarbonyl, aminocarbonyl, arylcarbonyl or heterocyclylcarbonyl optionally substituted by halogen, nitro, cyano, C 1 –C 6 alkyl or alkoxy; ix) C 1 –C 6 alkylcarbonylamino, alkyloxycarbonylamino, arylalkyloxycarbonylamino, arylcarbonylamino or aryloxycarbonylamino; x) carboxy, C 1 –C 6 alkylcarbonyloxy or arylcarbonyloxy; Y is a single bond or a divalent group selected from carbonyl (>C═O), aminocarbonyl (—NHCO—) or sulphonyl (—SO 2 —); C is benzene, naphthalene or an optionally benzocondensed 5 or 6 membered heterocycle having 1 or 2 heteroatoms selected among nitrogen, oxygen or sulphur; each of which being optionally further substituted by one or more groups selected from halogen, nitro, cyano, straight or branched C 1 –C 6 alkyl or alkoxy, alkylsulphonyl or aryl groups; or a pharmaceutically acceptable salt thereof.
