title: Docking and in silico ADMET studies of noraristeromycin, curcumin and its derivatives with Plasmodium falciparum SAH hydrolase: a molecular drug target against malaria.
abstract: The Plasmodium falciparum S-adenosyl-L-homocysteine hydrolase (pfSAHH) enzyme has been considered as a potential chemotherapeutic target against malaria due to the amino acid differences found on binding sites of pfSAHH related to human SAHH. It has been reported that noraristeromycin and some curcumin derivatives have potential binding with the largest cavity of pfSAHH, which is also related to the binding with Nicotinamide-Adenine-Dinucleotide (NAD) and Adenosine (ADN). Our present work focuses on docking and ADMET studies to select potential inhibitors of pfSAHH. The binding of the selected inhibitor of the PfSAHH active site was analyzed using Molegro Virtual Docker. In this study, curcumin and its derivatives have been found to have higher binding affinity with pfSAHH than noraristeromycin. Seven amino acid residues Leu53, His54, Thr56, Lys230, Gly397, His398 and Phe407 of pfSAHH involved in binding with curcumin, are the same as those for noraristeromycin, which reveals that curcumin and noraristeromycin bind in the same region of pfSAHH. Curcumin has shown a strong interaction with hydrophobic amino acid residues of pfSAHH. Molecular Docking and ADMET predictions suggest that curcumin can be a potent inhibitor of pfSAHH with ability to modulate the target in comparatively smaller dose. Therefore, curcumin is likely to become a good lead molecule for the development of effective drug against malaria.
