چکیده انگلیسی
Plasmodium falciparum calcium-ATPase (PfATP6) has been reported to be a target of artemisinin and related endoperoxides. In this study, a series of previously reported guaianolide-endoperoxides (thaperoxides) were docked into a homology model of PfATP6 and also used to develop a pharmacophore model. This combined approach led to useful insights into the binding determinants of thaperoxides to the malarial enzyme. In addition, in silico mutagenesis and molecular dynamics suggested the importance of Phe264 and the electrostatic interactions between Lys260 in helix H3 and Lys1036 and Asp1038 in L6/7 loop for the binding of thaperoxides. These results could help in the design of more potent inhibitors of PfATP6.
