Cell Cycle Arrest and Induction of Apoptosis in Colon Adenocarcinoma Cells by a DNA Intercalative Quinoline Derivative, 4-Morpholinopyrimido [4′,5′:4,5] Selenolo (2,3-b) Quinoline
Abstract:Circular dichroism, topological studies, molecular docking, absorbance, and fluorescence spectral titrations were employed to study the interaction of 4-morpholinopyrimido [4',5':4,5] selenolo (2,3-b) quinoline (MPSQ) with DNA. The association constants of MPSQ-DNA interactions were of the order of 10(4) M(-1). Melting temperature, topological, and docking studies confirmed that the mode of interaction was by intercalation with preference to d(GpC)-d(CpG) site of DNA. Cytotoxicity studies showed the MPSQ-induc… Show more
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.
