DNA Intercalators and Using Them as Anticancer Drugs
Many anticancer drugs in clinical use interact with DNA through intercalation, which is process that starts with the transfer of the intercalating molecule from an aqueous environment to the hydrophobic space between two adjacent DNA base pairs. In general, intercalatig agents are two types: monofunctional and bifunctional. Monofunctional intercalators contain one intercalating unit and Bifunct...
متن کاملSuppression of autophagy by FIP200 deletion impairs DNA damage repair and increases cell death upon treatments with anticancer agents.
Autophagy is a lysosomal bulk degradation process for intracellular protein and organelles. FIP200 (200 kDa FAK-family interacting protein) is an essential component of mammalian autophagy that is implicated in breast cancer in recent studies. Here we show that inactivation of FIP200 resulted in deficient repair of DNA damage induced by ionizing radiation and anticancer agents in mouse embryoni...

متن کاملDifferential toxicities of anticancer agents among DNA repair and checkpoint mutants of Saccharomyces cerevisiae.
Most cytotoxic anticancer agents damage DNA directly, interfere with DNA metabolism or chromosome segregation, and are particularly toxic in dividing cells. Although a considerable amount of information on the mechanisms of action of these agents is available, the molecular bases for selective tumor cell killing by chemotherapy are largely unknown. Many genetic alterations found in sporadic and...
متن کاملMonofunctional platinum-DNA adducts are strong inhibitors of transcription and substrates for nucleotide excision repair in live mammalian cells.
To overcome drug resistance and reduce the side effects of cisplatin, a widely used antineoplastic agent, major efforts have been made to develop next generation platinum-based anticancer drugs. Because cisplatin-DNA adducts block RNA polymerase II unless removed by transcription-coupled excision repair, compounds that react similarly but elude repair are desirable. The monofunctional platinum ...
