Abstract

Antioxidants can prevent reactive oxygen-associated diseases, which trigger carcinogenesis, cardiovascular disease, and premature aging. India and Africa have mostly practiced sausage trees (Kigelia africana) as traditional medicine, whereas Indonesia is still limited. The research aims to determine the phytochemistry and bioactivity of the n-hexane fractions from crude methanol extract of the leaves and bark of the sausage tree as antioxidants and their toxicity. The sausage tree is derived from Waterpark Platinum Riau. The sausage trees were macerated with methanol and fractionated by n-hexane and ethyl acetate. All samples were tested for their antioxidant to 1,1-diphenyl-2-picrylhydrazyl (DPPH) and cytotoxicity to Artemia salina Leach larvae. Phytochemical results of methanol crude extract, n-hexane, and ethyl acetate fractions of leaves and sausage bark showed the presence of all secondary metabolites except alkaloids in the n-hexane fraction. Antioxidant and cytotoxic activity of stem and leaf bark ethyl acetate fraction was stronger than crude methanol extract and n-hexane fraction. Based on LC-MS/MS data, the secondary metabolite components that have contributed strongly antioxidant activity of this study are flavonoid compounds such as kaempferol and the derivatives, lignans (cubebin), and steroids (pregnant).

Abstract

Diabetes mellitus (DM) is a chronic metabolic disease distinguished by disrupted glucose metabolism, causing elevated blood sugar levels. One of the latest therapeutic strategies involves inhibiting dipeptidyl peptidase-4 (DPP-4) to regulate glucose metabolism. Emodin, a bioactive compound, has shown potential as a DPP-4 inhibitor, but its efficacy requires further research. This study aims to identify and assess emodin and its derivatives as potential DPP-4 inhibitors through a comprehensive in silico and in vitro analysis. Molecular docking analysis revealed that 3-ρ-toluoyl emodin (ρTE) had the lowest binding energy (-111.4 kcal/mol) among the tested compounds. Furthermore, in vitro testing showed consistent results in silico, indicating that ρTE had significant inhibitory activity with an IC50 value of 1.37 μM. Pharmacokinetic and physicochemical evaluations confirmed ρTE’s potential as a safe antidiabetic drug candidate. The research findings indicate that ρTE holds potential as a promising drug candidate for further development.
