Lymphatic filariasis (LF) remains a significant health challenge for populations in developing countries. LF is a parasitic disease transmitted by mosquitoes, mainly caused by the filarial nematode, Wuchereria bancrofti, prevalent in tropical and subtropical regions. Since the present drugs develop complications, including adverse side effects, lack of specificity, and development of drug resistance, the present study focused on developing the potential anti-filariasis drugs targeting crucial proteins for the nematode life cycle. We have identified the therapeutic compounds by targeting the enzyme thioredoxin peroxidase 1 (WbTPx1), which facilitates the conversion of hydrogen peroxide into water, an essential mechanism by which the nematode survives against oxidative stress in the host. This approach might resolve treatment efficacy and activity difficulties at various stages of filarial parasitic worms. We modeled the structure of WbTPx1 and employed the structure-based virtual screening approach, focusing on the dimer interface region of the protein. ADMET prediction profiles of the non-toxic, top-ranked hits with higher docking scores demonstrate higher affinity to the nematode protein than its human homolog. The molecular dynamic simulation studies show WbTPx1-hit complexes' stability and the intactness of hits in the binding site. Further, in vitro validation of identified hits using Setaria digitata, a cattle nematode, showed better IC and higher inhibition than the standard drug ivermectin, indicating the potential to inhibit enzyme activity and the development of drug candidates for controlling LF.
