Dynamics simulation of the interaction between the novel intercalator diethidium cation and B-form DNA.

abstract：:Previous reports have shown that protein-drug interaction helps to improve the pharmacokinetics of the drugs. Human serum albumin (HSA) is one of the basic components of blood plasma and it serves as a storage and carrier protein. In the present study, the interaction of a new synthesized Pt [iso]2 complex (cis - [Pt(...
