2.5.1.15 | 4-[[(2-amino-4-oxo-3,4-dihydropteridin-6-yl)methyl]amino]-N-(3,4-dimethyl-1,2-oxazol-5-yl)benzene-1-sulfonamide | drug-resistant strains of Helicobacter pylori and multitudinous drug reactions are obstacles in the treatment of Helicobacter pylori infections a reliable tertiary structure of dihydropteroate synthase in complex with inhibitor 4-[[(2-amino-4-oxo-3,4-dihydropteridin-6-yl)methyl]amino]-N-(3,4-dimethyl-1,2-oxazol-5-yl)benzene-1-sulfonamide is constructed by Modeler 9v19. DrugBank compounds of DHPS, published inhibitors, and co-crystal ligand (4-[[(2-amino-4-oxo-3,4-dihydropteridin-6-yl)methyl]amino]-N-(3,4-dimethyl-1,2-oxazol-5-yl)benzene-1-sulfonamide) are docked against dihydropteroate synthase. The best docked compounds are screened against 28.5 million compounds result 1186 structural analogs. Virtual screening workflow and quantum polarized ligand dockings of these compounds against dihydropteroate synthase result three leads that show better XP Gscores, ADME properties, and binding-free energies compared to 4-[[(2-amino-4-oxo-3,4-dihydropteridin-6-yl)methyl]amino]-N-(3,4-dimethyl-1,2-oxazol-5-yl)benzene-1-sulfonamide, DrugBank compounds, and published inhibitors. The proposed leads are also validated by receiver operative characteristic (ROC) curve metrics in the presence of thousand decoys and the best docked existing compounds against DHPS. Long-range molecular dynamics (MD) simulations for 100 ns are executed after post-docking evaluations. Trajectory analysis shows that inter-molecular interactions of the lead-dihydropteroate synthase docking complex are stable throughout the entire runtime of MD simulations than 6MB-DHPS complex and Eliglustat-DHPS complex. The study outcomes showed good competitive binding propensity and active-tunneling of leads over the existing inhibitors, thereby these leads could be ideal inhibitors against dihydropteroate synthase to target Helicobacter pylori | Helicobacter pylori | |
