Patent ID: 7223794

Claim:
A compound of formula (I) wherein: X represents H, C1 to 4 alkyl, C1 to 4 alkoxy, halogen, OH, CN, C≡CH, NO 2 , CHO, COCH 3 or NHCHO; said alkyl or alkoxy group being optionally further substituted by one or more fluorine atoms or by an OH group; Y represents C1 to 4 alkyl, C1 to 4 alkoxy, halogen, OH, CN, C≡CH, NO 2 , CHO, COCH 3 or NHCHO; said alkyl or alkoxy group being optionally further substituted by one or more fluorine atoms; Either one of T, U and W represents N and the other two independently represent CR 4 ; or each of T, U and W represents CR 4 ; and each R 4 group independently represents H, F or CH 3 ; V represents O or S(O) n ; n represents an integer 0, 1 or 2; R 1 represents C2 to 4 alkenyl, C2 to 4 alkynyl, C3 to 6 cycloalkyl or a 4 to 8 membered saturated heterocyclic ring incorporating one heteroatom selected from O, S and N; any of said groups being optionally further substituted by C1 to 4 alkyl, C1 to 4 alkoxy, C1 to 4 alkylthio, C3 to 6 cycloalkyl, one or more halogens or phenyl; said phenyl group being optionally further substituted by one or more substituents selected independently from halogen, C1 to 4 alkyl, C1 to 4 alkoxy, CF 3 , OCF 3 , CN or NO 2 ; or R 1 represents phenyl or a five or six membered aromatic heterocyclic ring containing 1 to 3 heteroatoms independently selected from O, S and N; said phenyl or aromatic heterocyclic ring being optionally substituted by one or more substituents selected independently from halogen, C1 to 4 alkyl, C1 to 4 alkoxy, OH, CN, NO 2 or NR 5 R 6 ; said alkyl or alkoxy group being optionally further substituted by one or more fluorine atoms; R 2 and R 3 independently represent H, C1 to 4 alkyl or C3 to 6 cycloalkyl; said alkyl group being optionally substituted by one or more substituents selected independently from C1 to 4 alkoxy, halogen, OH, NR 7 R 8 , ═NR 7 , phenyl or a five or six membered aromatic or saturated heterocyclic ring containing 1 to 3 heteroatoms independently selected from O, S and N; said phenyl or aromatic heterocyclic ring being optionally further substituted by halogen, C1 to 4 alkyl, C1 to 4 alkoxy, CF 3 , OCF 3 , CN or NO 2 ; and R 5 , R 6 , R 7 and R 8 independently represent H or C1 to 4 alkyl; or a pharmaceutically acceptable salt thereof.
