In silico molecular docking shows the binding interaction of serverogenin acetate ([3,12-diacetyloxy-10,14-dimethyl-13-oxo-15-(5-oxo-2H-furan-3-yl)-2-oxapentacyclo[9.7.0.01,3.05,10.014,18]octadecan-7-yl] acetate) compound with α-amylase target protein (i-tasser) based on the binding energy generated by AutoDock program. (a) A hydrogen-bond interaction is formed by O26 in HE2, O27 in HE1, O34 in HE2, TRP59 (grey arrow), GLN63 (orange arrow), HIS305 (pink arrow) and ASP356 (purple arrow) in the serverogenin acetate compound. (b) A close-up view of serverogenin acetate compound that binds to the α-amylase target protein. (c) Binding pose of α-amylase target protein with serverogenin acetate compound.
