Abstract:
Over the past twenty years, the prevalence of diabetes as one of the most common metabolic diseases has become a public health problem worldwide [1]. Blood glucose control is an important factor in delaying the onset and progression of diabetes-related complications [2]. Therefore, in this study, curcumin- polyhydroxy derivatives were synthesized and used as effective agents in the treatment of diabetes with inhibitory properties against two carbohydrate-hydrolyzing enzymes α-glucosidase (α-Glu) and α-amylase (α-Amy) which are known to be significant therapeutic targets for the reduction of postprandial hyperglycemia [3]. In search of potent dual inhibitors of α-Amy and α-Glu, we have synthesized curcumin-polyhydroxy derivatives, characterized by FTIR and MS then the binding interaction details of compounds to α-Amy and α-Glu were determined using a molecular docking study. Molecular docking was performed using AutoDock Vina and docking results were analyzed by PyMOL v.2.3.2.1 and LigPlot+ v.1.4.2 software. Molecular docking indicated that curcumin derivatives mainly interacted with amino acid residues located in the active site of α-Amy and α-Glu. The binding energies obtained from the docking of α-Amy with curcumin (C1), C2, C3, and C4 derivatives were -8.4, -8.2, -8.5 and -8.7, kcal/mol, respectively. Also, C1, C2, C3, and C4 derivatives showed binding energies of -7.6, -7.8, -8.0 and -8.0 kcal/mol in communication with the active site of α-Glu, respectively. This study indicated that curcumin-polyhydroxy derivatives could occupy the active catalytic site of α-Amy and α-Glu, resulting in the inhibitory effect due to steric hindrance, but more preclinical and clinical studies should be carried out in the future.
