Novel p38 inhibitors with potent oral efficacy in several models of rheumatoid arthritis
摘要:
A library of trisubstituted oxazoles, thiazoles, imidazoles (1,2,4- and 2,4,5-substituted) and imidazo[1,2-b]pyridines was prepared and evaluated in vitro as p38alpha inhibitors and in vivo in several models of rheumatoid arthritis. Four structures 32, 37, 45 and 59-were identified as potent inhibitors of p38alpha with high efficacy in the LPS induced TNFalpha release model in the mouse, the adjuvant induced arthritis and the collagen induced arthritis in the rat with ED(50)s between 1.0 and 9.5 mg/kg p.o.
