9 Hexyl 9H carbazole 3 carboxylic acid (LCOOH) and its complex with Ph 3 Sn(OH), [Ph 3 SnO 2 CL] (I), were synthesized. The structure of complex I was solved by single crystal X ray diffraction determination, indicating that I shows the discrete framework. Furthermore, this complex was tested in vitro for its cytotoxic activity, using human hepatocellular carcinoma cell line (BEL 7402) and human hepatocel lular liver carcinoma cell line (HepG2); 5 fluorouracil was used as a positive control substance. This complex showed cytotoxicity greater than that of 5 fluorouracil.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
