Molecular docking studies of inhibitory activities of Phytochemicals in Calotropis procera against α-glucosidase hydrolase Sus B.

Abstract

The use of synthetic drugs is associated with various side effects and it is important to look for other drugs from medicinal plants. Therefore, this study aimed at assessing the inhibitory activities of Calotropis procera leaf against α-glucosidase hydrolase Sus B and it‟s possible mode of inhibiting this enzyme through molecular docking studies. From the molecular docking analysis, the results shows that out of the thirty six (36) screened phytochemicals, only twenty six (26) fall between the recommended hit value of inhibition constant of (0.1-1.0 µM) where their inhibition constant range from (0.01-0.59 µM) after docking with target receptor α-glucosidase hydrolase SusB (PDB ID: 2ZQ0) using Pyrx-vitual screening tools (Autodock tool, Autodock vina and Open babel).Visualizing was done using Pymol and Biosvia discovery studio(2019). Considering the other analysis done, Drug likeness of Lipinski rule of five, only six(6): Hesperidine (3),Calotroposide (3),Calotropin (3),Ascleposide (4),Proceroside (4) and Voruschairin (3) out of the potent twenty six (26) contravene more than 2 of the Lipinski rules of five, therefore other twenty (20) compounds can be considered for processing into potent drugs.

“…[9][10][11] To gain insight into the interaction between a ligand and a protein, particularly in drug discovery, molecular docking is employed. 12,13 It provides valuable predictions regarding the most probable binding mode of a compound with a protein. 14 Combined with ADMET properties, molecular docking can offer useful insights into the drug-like properties of compounds and the biochemical pathways and molecular mechanisms of drug-protein interactions.…”
