In vitro cytotoxicity of carbazole derivatives. V. 9-Halogeno-substituted 5,11-dimethyl-6H-pyrido[3,2-b]carbazoles
摘要:
Thirty-seven new 5,11-dimethyl-6H-pyrido[3,2-b]carbazole derivatives have been synthesized. These compounds are structurally related to the 5,11-dimethyl-6H-pyrido[4,3-b]carbazole antitumor drug ellipticine. They bear either a fluorine, a bromine or a chlorine atom on position 9, and are variously substituted on the pyridine ring. Twenty-nine of these compounds (78%) were found active when tested in vitro for their cytotoxic activity in a clonogenic assay using murine leukemia L1210 cell line. Structure-activity relationships are described in detail.
