ABSTRACT
A series of N-(4-phenyl-1, 3-thiazol-2-yl)-N'- phenylureas (5a-z) was synthesized from 2-amino-4-substituted phenylthiazoles and phenylisocyanates. The newly synthesized compounds were characterized by IR, (1)H NMR and Mass spectral data. All the twenty six N-(4-phenyl-1, 3-thiazol-2-yl)-N'-phenylurea derivatives were screened for antiinflammatory activity by following carrageenan induced rat paw edema method. Among the compounds screened, N-[4- (4-methoxy phenyl)-1, 3-thiazol-2-yl)-N'-phenylurea and N-[4-(4-methoxy phenyl-1, 3-thiazol-2-yl)-N'-(4-bromophenyl) urea were found to be more potent. The molecular docking interaction of aforementioned urea compounds revealed the traditional type II p38 kinase inhibitor's interactions in the DFG out active site.
