DUROJAYE, Olanrewaju A. et al. Evaluation of 6-Gingerol and its modified analogues as therapeutic candidates against Schistosoma mansoni phosphofructokinase. Vaccimonitor [online]. 2019, vol.28, n.1, pp. 38-47. ISSN 1025-0298.

The African most prevalent tropical disease after malaria is schistosomiasis and this disease in the developing countries is a massive socio-economic and public health burden. The disease also caused over 200,000 deaths. The development and design of new and novel antischistosomal drugs is now very important, as there are no vaccines currently and there is only one drug at the moment for the treatment of schistosomiasis. In this article, 6-gingerol was docked against the Schistosoma mansoni phosphofructokinase and the docking result was compared to those obtained from the docking of its modified analogues against the same enzyme. The chemical structure of 6-gingerol was obtained from the PubChem database while the modified analogues were designed using the ChemAxon software. The molecular docking procedure was carried out with the aid of the AutoDock Vina software while polar interactions which were eventually used in predicting the amino acid residues at the Schistosoma mansoni phosphofructokinase active site were visualized using the Pymol software. The Schistosoma mansoni phosphofructokinase 3D crystallized structure was modeled using the Swiss Model server. The molecular docking result showed that the modifications made on 6-gingerol had a positive effect on the binding energy of the compound to the enzyme active site as an appreciable increase was observed. 6-Gingerol and its modified analogues also violated none of the Lipinski’s rule with suggests that the experimental compounds are drug-like. The C2H5 analogue of 6 gingerol was selected as the ideal therapeutic agent based on the pharmacokinetics study and the exhibited binding energy.
