The docking results revealed that the bioactive compound flavan-4-ol, among all the 50 compounds studied, best docked to all the four targets of lifestyle diseases, viz., Human dipeptidyl peptidase IV (−5.94 kcal mol−1 binding energy), Sodium-glucose cotransporter-2 (−6.49 kcal mol−1) diabetes-related enzyme, the Human angiotensin-converting enzyme (−6.31 kcal mol−1) which plays a significant role in hypertension, and Proprotein convertase subtilisin kexin type 9 (−4.67 kcal mol−1) for atherosclerosis. This evidence concerns the gene DPP4 and diabetes mellitus.
