Fig. 2From: Docking simulation between HIV peptidase inhibitors and Trypanosoma cruzi aspartyl peptidaseIntermolecular interactions between the two T. cruzi aspartyl peptidase domains and the inhibitor compounds. We selected the three compounds with higher hits (A–F) and the two with lower hits in docking simulations (G–J). Hydrogen bond interactions observed between TcRP-A (A–C; G, H) and TcRP-B (D–F; I, J), and the three compounds that gave the higher hits after the molecular docking simulation: pepstatin A (A, D), ritonavir (B, E) and lopinavir (C, F); and the two compounds with lower hits: atazanavir (G, I) and benznidazole (H, J)Back to article page
