The different interactions of two anticancer drugs with bovine serum albumin based on multi-spectrum method combined with molecular dynamics simulations
Copyright © 2021. Published by Elsevier B.V..
Paclitaxel is the best natural anticancer drug and artemisinin also has anticancer effect. In this study, the interactions between BSA and these two drugs were determined in PBS (pH 7.40) by multi-spectroscopic method and molecular dynamics (MD) simulations. The results showed that paclitaxel and artemisinin could statically quench the BSA fluorescence when the complexes were formed and the stoichiometric ratio of BSA-drugs was 1:1. Particularly, the BSA-paclitaxel complex was more stable than BSA-artemisinin complex. During the binding, the surroundings around Trp residue site was largely affected than Tyr site, especially Trp 214 to a more hydrophobic environment. In addition, the binding processes were mainly spontaneous through electrostatic force interaction. In summary, we concluded that the free drug of paclitaxel in blood was low and duration time of artemisinin was shorter.
