Thioredoxin reductase 1 (TrxR1) is an oxidoreductase playing the important role in the tumor cells. It is a new type of drug therapy target. Most of the existing TrxR1 inhibitors act directly covalently on the active sites. Herein, molecular docking-based virtual screening approach was used to screen inhibitors with new binding site of TrxR1 from the SPECS database. After experimental test, compound22was identified as the reversibility inhibitor of TrxR1 U498C mutant (It has similar structure and function to replace the wild-type TrxR1 which is difficult to express) with IC50value of 15.31 ± 0.57 μM. The molecular docking results showed that the interaction between compound22and TrxR1 was centered on inactive site Trp114. Furthermore, phenazine compounds24–30with similar structures as22were also screened out from our phenazine database. Compounds24–27had longer chain structures and better inhibitory activity than compound22, while compounds28–30were the opposite. Compounds24–27can be more stably bound in the protein cavity on Trp114than compounds28–30. Then we verified amino acids centered on Trp114can regulate TrxR1 activity by amino acids mutation. Taken together, A new inhibition site are found that can regulate TrxR1 U498C mutant activity by acting on amino acids sequence at inactive sites centered on Trp114and can provide ideas for the discovery and research of new TrxR1 inhibitors.
