Abstract

A series of novel 5-((1-aroyl-1H-indol-3-yl)methylene)-2-thioxodihydropyrimidine-4,6(1H,5H)-diones (3a-z) have been evaluated for in vitro cytotoxicity against a panel of 60 human tumor cell lines. Compound 3k exhibited the most potent growth inhibition against melanoma MDA-MB-435 cells (GI(50)=850 nM), against leukemia SR cancer cells (GI(50)=1.45 μM), and OVCAR-3 (GI(50)=1.26 μM) ovarian cancer cell lines. The structurally related compound 3s had a GI(50) value of 1.77 μM against MDA-MB-435 cells. The N-naphthoyl analogue 3t had GI(50) values of 1.30 and 1.91 μM against HOP-92 non-small cell lung cancer and MDA-MB-435 melanoma cell lines, respectively. The related analogue 3w had GI(50) values of 1.09 μM against HOP-92 non-small cell lung cancer cell lines. Interestingly, docking of the two active molecules 3k and 3w into the active site of COX-2 indicates that these compounds are COX-2 ligands with strong hydrophobic and hydrogen bonding interactions. Thus, compounds 3k, 3t, 3s, and 3w constitute a new class of anticancer/anti-inflammatory agents that may have unique potential for cancer therapy. Copyright © 2013 Elsevier Ltd.
