Molecular docking and dynamic studies of novel phytoconstituents in an investigation of the potential inhibition of protein kinase C- beta II in diabetic neuropathy

Abstract

Diabetic neuropathy, a debilitating complication of diabetes, necessitates innovative therapeutic interventions targeting Protein Kinase C-beta II (PKC-beta II). This study derives its rationale from the             established antioxidant, anti-inflammatory, and hypoglycemic attributes of Piperine, Columbin, Phyllodulcin, Caftaric acid, Esculentin, and Hydrangenol. The primary objective is to computationally unravel the inhibitory potential of these phytoconstituents against PKC-beta II. Methodologically, molecular docking employing AutoDock Vina facilitated the assessment of binding affinities. Swiss ADME and pkCSM platforms were harnessed for ADME attributes and toxicity profiles, ensuring compound safety and absorption. Molecular dynamics simulations via GROMACS ensured the stability of protein-ligand complexes. Calculations of binding free energy, hydrophobic interactions, charge distribution, aromatic character, and Surface Area Solvent (SAS) augmented the evaluation of PKC-beta II inhibitory potential. High-throughput screening, comparing with established inhibitors, further corroborated their promise. In culmination, the computational exploration demonstrates the propitious inhibition potential of the selected phytoconstituents against PKC-beta II, substantiated by favorable binding affinities, robust ADME profiles, and molecular dynamics stability.
