Design, synthesis, and antitumor evaluation of 2,4,6-triaryl pyridines containing chlorophenyl and phenolic moiety
摘要:
We have designed and synthesized a series of 2,4,6-triaryl pyridine derivatives containing chlorophenyl and phenolic moeity at 2- and 4- position of the central pyridine, respectively, resulting in a total of 42 compounds. They were evaluated for topoisomerase I and 11 inhibitory activities as well as cytotoxicities against several human cancer cell lines. Most compounds showed better topoisomerase II inhibitory activity compared to topoisomerase 1 inhibitory activity. Compounds 19, 20, 26-28, and 47-50 especially showed stronger topo II inhibitory activity than etoposide. (C) 2012 Elsevier Masson SAS. All rights reserved.
