Abstract: Two series of novel 4-chloro-2-(benzylthio)-5-(1,3,4-oxadiazol-2-yl)benzenesulfonamides and their N-aroyl derivatives have been synthesized and evaluated for in vitro anticancer activity against the full NCI-60 cell line panel. Most of the compounds exhibited antiproliferative activity. Among them a compound bearing an N-(thien-2-ylcarbonyl) moiety showed broad-spectrum activity with 50% growth inhibition (GI50) values in the range of 2.02-7.82 μM over 50 cell lines.
Keywords: 2-Mercaptobenzenesulfonamides; Acylsulfonamides; Antitumor agents; Heterocycles; Phase-transfer catalysis.
