Novel 6-[(hetero)arylamino]thieno[3,2-b]pyridines: Synthesis and antitumoral activities
摘要:
Several novel 6-[(hetero)arylamino]thieno[3,2-b]pyridines were prepared by palladium-catalyzed C-N Buchwald-Hartwig coupling of the methyl 3-amino-6-bromothieno[3,2-b]pyridine-2-carboxylate with aryl and heteroarylamines, using different reaction conditions. The antitumoral activity of the di(hetero) arylamines obtained was evaluated against three representative human tumor cell lines, namely breast adenocarcinoma (MCF-7), melanoma (A375-05), and non-small cell lung cancer (NCI-H460) and some structure activity relationships were established within each series. The most promising compounds were shown to be a benzothiazole derivative with GI(50) 3.5-6.9 mu M followed by an indole derivative with GI(50) 13-21 mu M. (C) 2010 Elsevier Masson SAS.
