Diabetes is the becoming one of the most common problem all over the world. About 1 in 10 persons are suffering from diabetes and most from type 2 diabetes. It occurs due to problem in pancreas which further results defect in the insulin secretion, as insulin maintains blood glucose level. The effect of Alpha-Amyrin Acetate, Myrcene and Vasicine compounds against Islet Amyloid polypeptide (IAPP) protein was seen through molecular docking studies. IAPP acts as complementary to insulin in regulating the sugar level for the treatment of diabetes disease by virtual screening. Different tools and software used in this research were Uniprot, Pubchem, Swiss ADMS, PyRx, Auto dock Vina/MGL tool and PyMOL.

DPP-4 is an important biological target related to the treatment of diabetes since some inhibitors can lead to an increase in the insulin levels and the prolonged activity of glucagon-like peptide-1 and gastric inhibitory polypeptide, being effective in glycemic control.

A 3D model of Cyclin-dependent kinase 5 (CDK5) (Accession Number: Q543f6) is generated based on crystal structure of P. falciparum PFPK5-indirubin-5-sulphonate ligand complex (PDB ID: 1V0O) at 2.30 Å resolution was used as template. Protein-ligand interaction studies were performed with flavonoids to explore structural features and binding mechanism of flavonoids as CDK5 (Cyclin-dependent kinase 5) inhibitors. The modelled structure was selected on the basis of least modeler objective function. The model was validated by PROCHECK. The predicted 3D model is reliable with 93.0% of amino acid residues in core region of the Ramachandran plot. Molecular docking studies with flavonoids viz., Diosmetin, Eriodictyol, Fortuneletin, Apigenin, Ayanin, Baicalein, Chrysoeriol and Chrysosplenol-D with modelled protein indicate that Diosmetin is the best inhibitor containing docking score of -8.23 kcal/mol. Cys83, Lys89, Asp84. The compound Diosmetin shows interactions with Cys83, Lys89, and Asp84.
