A compound of the formula: n n n and its pharmaceutically effective salts, wherein R 1 and R 2 are independently selected from the following: n (a) hydrogen, halo, R 5 —, C 2-6 alkenyl, C 2-6 alkynyl, hydroxy-R 5 —, R 5 —O—R 5 —, or the like; (b) Ar—, Ar—R 5 —, Ar—C 2-6 alkenyl, Ar—C 2-6 alkynyl, Ar—O—, Ar—O—R 5 — or the like; (c) R 5 —C(O)—, —NO 2 , cyano, NH 2 —C(O)—, R 5 —NH—C(O)—, (R 5 ) 2 —N—C(O)—, Ar—C(O)— or the like; and (d) R 5 —C(O)—NH—, Ar—C(O)—NH— or the like; wherein Ar is optionally substituted aryl or heteroaryl such as phenyl and pyridyl; and wherein R 5 is optionally halo-substituted C 1-6 alkyl; R 3 is selected from the following: (e) cyano, formyl, tetrazolyl, triazolyl, imidazolyl, oxazolyl, thiazolyl, R 5 —C(O)—, C 2-6 alkenyl-C(O)—, C 2-6 alkynyl—C(O)—, R 5 —C(O)—R 5 —, or the like; (f) R 5 —C(O)—NH—, Ar—C(O)—NH—, or the like; (g) R 5 —S—, R 5 —S(O)—, R 5 —NH—S(O) 2 —, or the like; and (h) Ar—C(O)—, Ar—R 5 —C(O)—, Ar—C 2-6 alkenylene-C(O)— or the like; or two of R 1 , R 2 and R 3 together form a group of the formula —A 1 —B 1 —A 2 — or —A 1 —B 1 —A 3 —B 2 —A 2 — such as cyclic alkyl optionally substitued with oxo; R 4 is hydrogen, halo, R 5 —C(O)— and the like; X is O, S, S(O) or S(O) 2 ; m is 0, 1, 2, 3 or 4. The present invention also provides processes for the preparation thereof, the use thereof in treating cytokine mediated diseases and/or cell adhesion molecule (CAM) mediated diseases and pharmaceutical compositions for use in such therapy. |
