Biochemical pharmacology and DNA-drug interactions by Cl-958, a new antitumor intercalator derived from a series of substituted 2H-[1]benzothiopyrano[4,3,2-cd]indazoles.


Cl-958, PD 121373, and PD 114595 belong to a new class of DNA complexers, substituted 2H-[1]benzothiopyrano[4,3,2-cd] indazoles, and are being further developed as antitumor drugs based on their curative properties against murine solid tumor models. The biochemical effects of these drugs on L1210 leukemia cells and their interaction with DNA were studied… (More)
