Through bioinformatics analysis, key proteins such as Carnitine palmitoyltransferase I, mitochondrial carnitine/acylcarnitine carrier protein, and PPARγ were identified, highlighting their importance in insulin sensitivity. Molecular docking results indicated that Naringenin has a strong binding affinity for GLUT4 and PPARγ, with binding energies of -8.18 kcal/mol and -8.21 kcal/mol, respectively. This suggests that Naringenin may modulate these proteins to enhance insulin sensitivity. In contrast, its weaker binding with Enhancer-Binding Protein Alpha points to Naringenin's selective efficacy among various targets. Molecular dynamics (MD) simulations conducted over 100 ns confirmed the stability of the GLUT4-Naringenin complex, showing a reduced RMSD of 1.25 nm and a more compact structure with a Radius of Gyration (Rg) value of 2.14 nm. However, Rho-related GTP exhibited increased instability upon Naringenin binding, indicating a potential inhibitory effect. Additionally, an in silico ADMET profile revealed Naringenin's favorable pharmacokinetics, including low hepatotoxicity, no mutagenic effects, and a high maximum tolerated dose, which supports its safety for drug development. In conclusion, Naringenin shows promising potential in enhancing glucose metabolism and insulin sensitivity, positioning it as a viable candidate for future preclinical and clinical studies in T2DM management.
