Aldose reductase, a key enzyme of the polyol pathway catalyses NADPH-dependent reduction of glucose to sorbitol. Increased activity of this enzyme is considered a major factor contributing to the development of diabetic complications hence could be an important target in the treatment of these complications. In this work, a database of sesquiterpenes was prepared and screened for their drug-like properties based on the Lipinski’s rule of 5. The co-crystallised structure of aldose reductase was obtained from the Protein Databank and prepared for docking. In silico docking experiments was performed on Autodock tools using 198 sesquiterpene lactones that passed screening, and compounds with the lowest binding energy and favourable binding interactions were selected for molecular docking simulation. Six of the best ranking compounds selected had binding energies ranging from–11.96 Kcal/mol to -9.45 Kcal/mol  and were comparable to the energy of the standard inhibitor Idd594 used in the study. They also show good complementarity in their binding to the residues of the binding pocket. The results suggest that dehydrooopodin (1), 11(S),13-dihydrolactucopicrin (2), and Chrysanin (3) offered potential inhibitory activities toward aldose reductase and may serve as lead compounds for in vivo validation as aldose reductase inhibitors.

AbstractIntroductionType 2 Diabetes Mellitus (T2DM) is a long-term metabolic disorder that primarily characterized by impaired insulin resistance to become hyperglycemia. People suffering from T2DM have a higher risk of developing various diseases but, on top of that, some diabetic drugs are also suspected of increasing the risk in some cases. Aldose reductase is a key target enzyme to catalyze the reduction of glucose to sorbitol and does not readily diffuse across cell membranes and cause retinopathy and neuropathy. The aldolase reductase inhibitors prevent the conversion of glucose to sorbitol and may have the capacity of preventing and / or treating several diabetic complications. It will be expected to be twofold in the subsequent decade due to intensification in the senile population with the number of people affected, thus adding to the liability on medical providers in poor developed countries using herbal medicine to control the diabetes. In recent investigation, the antidiabetic property of phytochemicals extracted from leafs of Abutilon indicum (L.) is elucidated using animal models.Materials and MethodsIn the current study using aldose reductase enzyme assay inhibitor of Rat lens Aldose reductase were treated with A. indicum methanolic leaf extract at different concentrations (6.25, 12.5, 25, 50, 100, and 200μg/mL). Copper sulphate was used as reference drug and docking studies to predict the screen the best aldose reductase inhibitor.Results and DiscussionThe crude extract exhibited cytotoxicity against rat lens aldose reductase (IC50 = 135.8 μg/L vs ref 13.60 μg/L) using In Vitro. The docking is performed with 11 compounds shows Ertugliflozin, 9H-Cycloisolongifolene, 8-oxo and 7-hydroxy cadalene showed a good binding interaction with aldose reductase.ConclusionWe are concluding that the invitro and in silico analysis helps researchers to utilize these compound for aldose reductase inhibitors and further can be used for clinical applications.

Abstract In this work, isatin was employed as the scaffold to design aldose reductase inhibitors with antioxidant activity. Most of the isatin derivatives were proved to be excellent in the inhibition of aldose reductase (ALR2) with IC 50 values at submicromolar level, and (E)-2-(5-(4-methoxystyryl)-2,3-dioxoindolin-1-yl) acetic acid (9g) was identified as the most effective with an IC 50 value of 0.015 μM. Moreover, compounds 9a-h with styryl side chains at the C5 position of isatin showed potent antioxidant activity. Particularly, the phenolic compound 9h demonstrated similar antioxidant activity with the well-known antioxidant Trolox. Structure-activity relationship and molecular docking studies showed that the acetic acid group at N1 and C5 p-hydroxystyryl side chain were the key structures to increase the aldose reductase inhibitory activity and antioxidant activity.
