Abstract
ObjectiveTo screen PPARγ agonists from natural products by molecular docking.
MethodsThis study was from January to December 2021. Based on the crystal structure of peroxisome proliferator-activated receptor gamma (PPARγ) (PDB Code: 6md4), a virtual target model was constructed. A total of 1 680 compounds in the natural product database were used as the ligands for screening, and the 6md4 pro-ligands were used as control. Firstly, the SYBYL software was used for the virtual screening of natural small molecular compounds, followed by high-precision molecular docking of the top 20 compounds, and finally the PyMol software was used to analyze the stable binding compounds.
ResultsAccording to the scoring results, crash, polar, 20 small-molecule PPAR gamma agonists, such as hesperidin, and the like, were finally screened out. Among them, hesperidin could form hydrogen bonds with many amino acids, such as PPARγSer289, His323, Tyr327, and so on.
ConclusionThe potential PPARγ agonists were screened from natural products so as to provide basis for the discovery of new anti-diabetic lead compounds or dietary supplements.
