Abstract
In this paper, catalpol propionylated analogs (CPs) were designed as drug ligands of glutathione peroxidase (GSH-Px) based on molecular docking (MD) using Surflex-Docking method. The calculated total scores (Total_score) and C log of CPs are higher than that of catalpol, which show that the CPs maybe served as potential lead compounds as new antiaging drugs. Furthermore, the maximum Total_score of isomers in one group CPs is often not that the molecule with minimum energy structure. These show that the CPs docking with GSH-Px maybe not only affected by the molecular energy, but also affected by their conformations. The CPs were synthesized by esterification of catalpol with propionic anhydride using pyridine as solvent and acid banding agent, DMAP as catalyst, reaction at specific temperature. The synthesized perpropionylated catalpol analog (CP-6) was determined by NMR, FT-IR, HRMS, and HPLC, and the synthesis process was optimized by means of orthogonal experimental design. Subsequently, CP-6 was screened for cells viability by MTT assay, the results show that the CP-6 can effectively reversed STZ-induced reduction of cells viability, and CP-6 has potential antiaging activity.
