Important Docking study of Structure of Plasmodium falciparum thioredoxin reductase-thioredoxin complex: the case of potent drug Telatinib, a small molecule angiogenesis inhibitor

Background Over the last decades, malaria parasites have been rapidly developing resistance against antimalarial drugs, which underlines the need for novel drug targets. Thioredoxin reductase (TrxR) is crucially involved in redox homeostasis and essential for Plasmodium falciparum. In this communication, we report first time important Docking study by in Silico approach, using AutoDock Vina. After a selective analysis of over 300 drugs, processed with Pyrx (a Virtual Screening software into the active site of protein (ID PDB 4J56 Thioredoxin reductase 2 Chain A), we noticed excellent value of Binding Energy of Telatinib estimated by Pyrx software. These results are comparable to the crystallized ligand FAD (FLAVIN-ADENINE DINUCLEOTIDE) completed in the above-mentioned protein. Indeed, from the results of Autodock Vina, Telatinib an inhibitor of tyrosine kinases, has excellent a Binding affinity value, ca. −12 kcal/mol.
