title: Synthesis, anticancer, and anti-inflammatory activity evaluation of methanesulfonamide and amidine derivatives of 3,4-diaryl-2-imino-4-thiazolines.
abstract: Condensation of 3,4-diaryl-2-imino-4-thiazoli-nes 1a-j with methanesulfonyl chloride gave methanesulfonamide derivatives 2a-j. Condensation of 2-cyanopyrazine, 4-cyanopyridine, and 2-cyanopyridine with 3,4-diaryl-2- imino-4-thiazolines 1h-m in the presence of sodium methoxide afforded amidine derivatives 3a-j. Compounds 2a-j and 3a-j were screened against various human cancer cell lines (COLO-205, HEP-2, A-549, IMR-32) and their percentage growth inhibition profile determined at 1 x 10(-5)M. The anti-inflammatory activity of these compounds was assessed using the carrageenan-induced paw edema model. Compound 2i exhibited 34.7% anti-inflammatory activity at 50 mg/kg p.o., which is comparable to standard care drug phenyl butazone (37% activity at 50 mg/kg p.o.).
