Design, Synthesis, and Biological Evaluation of Selenium-incorporated Aminopyridazines as Anticancer Agents

摘要

A new series of 3-alkylseleno-6-alkylaminopyridazines, 3-alkylseleno-6-alkyliminopyridazines, and 3-alkylseleno-6-dialkylaminopyridazines was synthesized from 3,6-dichloropyridazine for development of new anticancer agents. The process involves the selenylation, Se-alkylation, and aralkylamination (or imination). The alkylamines such as ethylamine and the dialkylamines such as dipropylamine were introduced into the 3-position of the pyridazine ring. These new compounds showed antiproliferative activities against breast cancer (MCF-7) and hepatocellular carcinoma (Hep3B) cells in CCK-8 assays and could be promising candidates for chemotherapy of carcinomas.
