potent ureaseinhibition activity. The chalcone 3-(3-hydroxyphenyl)-1-phenylpropenone was found to be the most potent with percentage inhibition 86.17 ± 0.89 and half maximal inhibitory concentration (IC50) value 11.51 ± 0.03 µM. The molecular docking study emphasized that the same congeners 3-(furan-2-yl)-1-(4-hydroxyphenyl)propenone, 3-(4-hydroxyphenyl)-1-(4-methoxyphenyl)propanone, and 3-[4-(dim
A series of novel pyrazolines (2a-l) bearing benzenesulfonamide moiety were synthesized by condensing appropriate chalcone (1a-l) with 4-hydrazinobenzenesulfonamide hydrochloride. Structure of all novel synthesized compounds was characterized on basis of elemental analysis data and spectral data (IR, (HNMR)-H-1, MS). Compounds (2a-l) were screened for in vivo anti-inflammatory action in carrageenan-induced rat paw edema model and blood glucose lowering action in glucose fed hyperglycemic normal rats. Compounds 2a, 2e, and 2l showed significant anti-inflammatory action (more than 75 %) at 5 h and also showed superior gastrointestinal safety profiles as compared to celecoxib. One compound (2i) was found to exhibit significant blood glucose lowering activity.

A new series of thirty-six dihydroxylated 2,6-diphenyl-4-aryl pyridines containing hydroxyl groups at the ortho, meta, or para position of 2- and 6-phenyl rings attached to the central pyridine were designed and synthesized. They were evaluated for topoisomerase I and II inhibitory activity and cytotoxicity against several human cancer cell lines for the development of novel anticancer agents. Most of the compounds with hydroxyl moiety either at the meta or para position of 2- or 6-phenyl ring in combination with thienyl or furyl group at 4-position of central pyridine displayed significant topoisomerase II inhibitory activity and cytotoxicity. Positive correlation between topoisomerase II inhibitory activity and cytotoxicity was observed for the compounds 9-11, 15-17, 19, 21-23, 28, and 41. Among all the synthesized compounds, compound 17 emerged as the most promising topoisomerase II inhibitor with significant cytotoxicity. (C) 2015 Elsevier Ltd. All rights reserved.
