ABSTRACT
Imidazole on reaction with 1-(4-chlorophenyl) ethanone in the presence of absolute ethanol gives 1-(4-(-imidazol-1-yl) phenyl) ethanone, condensation of this with various aromatic aldehydes offered 1-(4-(Imidazol-1-yl)phenyl) -3-phenylprop-2-en-1-one, (1), which on cyclization with Thiourea yielded 4-(4-(1H-imidazol-1-yl)phenyl)-6-phenylpyrimidine-2(1H)-thione (2a-2e). The structures of newly synthesized compounds were confirmed by FTIR, 1HNMR, MASS spectral data. Compounds were screened for invitro anti-inflammatory activity by Inhibition of Albumin Denaturation technique and Antiproteinase action. All the synthesized substituted thiopyrimidine
compounds have shown moderate to good anti inflammatory activity.
Keywords: Imidazole, 1-(4-chlorophenyl) ethanone, Aromatic aldehydes, Thiourea, Anti-inflammatory activity.
