3-chloromethylene-6-fluorothiochroman-4-one, A novel DNA Topoisomerase poison.


3-Chloromethylene-6-fluorothiochroman-4-one (CMFT) is a novel thiochromanones derivative that has better anti-tumor activity. In this paper, we will compare the antitumor activity of the cis-trans isomers, and explore their inhibiting effects on human topoisomerase I and topoisomerase II in cell free reaction system. The MTT method was used to study… (More)
