BACKGROUND OBJECTIVES: Plasmodium falciparum is the most dangerous species of the malaria-causing parasite and remains a significant global health threat. Despite advances in understanding malaria and its pathology, effective treatments are limited, and drug development remains challenging. Computational techniques assist in screening potential drug candidates by simulating interactions between small molecules and target enzymes.
METHODS: In this study, Density Functional Theory (DFT), ADME analysis, and molecular docking studies were carried out against the ATP-dependent DNA helicase (UvrD) protein of Plasmodium falciparum 3D7, using three biologically active compounds: Betulinic acid, Celastrol, and Vitamin D3.
RESULTS: Theoretical calculations suggest that all three compounds (Betulinic acid, Celastrol, and Vitamin D3) have strong binding affinity toward Plasmodium falciparum targets. These findings may offer a novel direction for antimalarial drug discovery.
INTERPRETATION CONCLUSION: Computational results predict that Compound 2 (Celastrol) exhibits stronger interactions with the target protein compared to the other two compounds. Its higher reactivity is further supported by a narrower HOMO-LUMO gap and molecular electrostatic potential (MEP) maps.
