Sumario: | Inhibition of the Tryparedoxin peroxidase interaction has been becomes a new therapeutic strategy in leishmaniasis. Docking analysis was carried out to study the effects of quercetin and taxifolin on Tryparedoxin Peroxidase (TryP). Tryparedoxin peroxidase of Trypanosomatidae functions as antioxidants through their Peroxidase and peroxynitrite reductase activities. The 3D models of Tryparedoxin Peroxidase of Leishmania braziliensis (L. braziliensis TryP) was modeled using the template Tryparedoxin Peroxidase I from Leishmania Major (L. Major TryPI) (PDB ID: 3TUE). Further, we evaluated for TryP inhibitory activity of flavonoids such as quercetin and taxifolin using in silico docking studies. Docking results showed the binding energies of - 11.8601and -8.0851 for that quercetin and taxifolin respectively. Flavonoids contributed better L. braziliensis TryP inhibitory activity because of its structural parameters. Thus, from our in silico studies we identify that quercetin and taxifolin posses anti-leishmanial acitivities mediated through TryP inhibition mechanism. |
