Synthesis, Characterization, and Molecular Docking Analysis of A Novel NHC Salt and Its Palladium-PEPPSI Complex

PEPPSI type Pd complexes have wide applications in recent years. Serum albumin carries very important molecules such as oleic and linoleic acids, nitric oxide, vitamin B6, thyroid and so do many drugs. In this study, a novel NHC molecule and its Pd-PEPPSI complex were synthesized and characterized. Both the ligand and the complex were optimized by DFT-based calculation methods. The binding properties of the molecules with HSA were analyzed by molecular docking methods. Binding affinity of -8.04 kcal/mol and inhibition constant of 1.29 µM were determined for NHC salt while the binding affinity was calculated as -7.04 kcal/mol and the inhibition constant as 6.92 µM for Pd-PEPPSI complex.
