With the aim of searching novel P-CABs, seven bisabolangelone oxime derivatives were designed, synthesized, characterized and evaluated the H+,K+-ATPase inhibitory activities guided by computer aided drug design methods. The binding free energy calculations were in good agreement with the experiment results with the correlation coefficient R of −0.9104 between ΔGbind and pIC50 of ligands. Compound 5 exhibited the best inhibitory activity (pIC50=6.36) and most favorable binding free energy (ΔGbind=−47.67kcal/mol) than other derivatives. The binding sites of these compounds were found to be the hydrophobic substituted groups with the Cys813 residue by the decomposed binding free energy analysis. |
