Abstract
Malarial infection due to P. falciparum is prominent cause in worldwide fatality. PfCRT, PfDHPS, PfMDR1 and PfDHFR1 play vital role as targets in malarial infection. We chose PfCRT-specific ligands for our study and tested them against all P. falciparum targets. The study was carried out by performing MDS and MD analyses with the NAMD and AutoDock softwares, respectively. The study's goal is to find potential ligands that can act on all malarial targets at various temperatures.The MDS studies revealed structural conformational changes and protein stability from normal human body temperature, 98.6 °F, to maximum human body temperature, 107 °F. This MDS analysis of Plasmodium targets was carried out by creating a graph of RMSD vs time. Further MD analysis revealed that the ligands reported against PfCRT also had a high binding energy against PfDHPS and PfDHFR. As a result, those ligands can also be targeted for Plasmodium falciparum proteins other than the three mentioned above. These ligands can be subjected to SAR and QSAR studies in order to develop novel molecules for malaria treatment.
