Abstract
Nuclear factor-kappaB (NF-kappa B) has been reported to regulate various genes involved in cancer and inflammation. Accordingly, drugs suppressing or inhibiting NF-kappa B may possess both anti-inflammatory and anticancer properties. A library of quinolone substituted thiazolidin-4-ones was docked into the active site of NF-kappa B and the top-ranked 31 compounds were synthesized and evaluated for anti-inflammatory and anticancer activity. The best-ranked compound 6b showed highest anti-inflammatory activity in carrageenan-induced paw edema model. In vitro anticancer studies revealed la and 16a as most active compounds against BT-549, HeLa, COLO-205 and ACHN human cancer cell lines. Compounds la and 16a exhibited NF-kappa B dependent anticancer properties and apoptosis mediated cell death. In vivo Ehrlich ascites carcinoma study further confirmed the antitumor activity of la and 16a. (C) 2013 Elsevier Masson SAS. All rights reserved.
