Xanthineoxidase is a complex molybdoflavoprotein that catalyses the hydroxylation of xanthine to uric acid. Fifty three analogues of 1-acetyl-3,5-diaryl-4,5-dihydro(1H)pyrazoles were rationallydesigned and synthesized and evaluated for in vitro xanthineoxidase inhibitory activity for the first time. Some notions about structure activity relationships are presented. Six compounds 41, 42, 44, 46,
Chalcone is an aromatic ketone that forms the central core for a variety of important biological compounds, which are collectively known as chalcones. The cytotoxic potential of chalcones which consists of C-6-C-3-C-6 units gets enhanced by the incorporation of pyrazole ring as proved by our earlier studies. Thus in the present work, pyrazoles of chalcones with ring A substituted by furan, naphthalene and variety of substituted phenyl rings has been prepared and evaluated for in vitro cytotoxic activity against PC-3, OVCAR, IMR-32, HEP-2 human cancer cell lines.All the synthesized compounds were evaluated for in vitro cytotoxicity against PC-3, OVCAR, IMR-32, HEP-2 human cancer cell lines. Compound 68 was found to be the most potent showing broad spectrum of cytotoxicity against all the cell lines .
