Introduction

Diabetes is a metabolic disease caused by impaired insulin secretion, leading to elevated blood sugar levels. Interleukin-10 (IL-10) is an anti-inflammatory mediator whose levels are reduced in diabetes conditions. The plant Acalypha indica (Ai) is one of the plants believed to inhibit inflammation occurring in diabetes. This study examines the effect of Ai administration on IL-10 levels in the serum of diabetic rats and analyzes the compounds in the roots of Ai that bind with IL-10 using molecular docking methods. Method

Experimental studies were performed on 25 male Sprague-Dawley rats, divided into five groups: normal diet group, DM group, DM+Ai250 group, DM+Ai400 group, and DM+Pioglitazone group. After 6 weeks, the rats were euthanized, and IL-10 levels in the serum were measured using ELISA. Subsequently, molecular docking studies were conducted using Molegro Virtual Docker 6.0 software on 55 compounds extracted from the roots of Ai to prove their affinity with IL-10 (PDB: 2H24) as the target protein. Results

Administration of Ai extract increased IL-10 concentration at doses of Ai 250 mg/Kg (46.26 (38.83-55.71) pg/mL) and Ai 400 mg/Kg (59.50 (40.23-176.10) pg/mL) compared to the DM group (44.03 (41.65-54.46) pg/mL), but not statistically significant. The compound 1.2.3.6-Tetragalloyl-beta-D-glucopyranose exhibited the best affinity and stability with the IL-10 receptor (PDB: 2H24), followed by naringin, acaindinin, clitorin, and gamma sitosterol, with RerankScores of -102.872, -102.661, -102.391, -86.9786, and -86.4227, respectively.

Conclusion

The administration of ethanol extract of Acalypha indica root did not increase IL-10 levels in the serum of diabetic experimental rats. The five main compounds of Ai that can bind with IL-10 are 1.2.3.6-Tetragalloyl-beta-D-glucopyranose, naringin, acaindinin, clitorin, and gamma sitosterol."
