Virtual screening, molecular docking, and molecular dynamics simulation studies on the hypoglycemic function of oat...

Area of Science:

• Nutritional biochemistry
• Computational drug discovery

Background:

• Oat peptides are known for their potential health benefits, including blood sugar regulation.
• Dipeptidyl peptidase-4 (DPP4) is a key target for type 2 diabetes treatment.

Purpose of the Study:

• To identify and evaluate oat peptides that can inhibit DPP4 activity.
• To provide a molecular basis for developing oat peptide-based DPP4 inhibitors.

Main Methods:

• Literature review and database construction of oat peptides.
• Virtual screening of oat peptides against the DPP4 protein.
• Molecular dynamics simulations and binding free energy calculations.

Main Results:

• A database of oat peptides was created and screened against DPP4.
• Six peptides showed stable binding to DPP4 after virtual screening.
• Two oat peptides exhibited strong affinity for DPP4, indicating potential as lead compounds.

Conclusions:

• Oat peptides can effectively bind to DPP4, offering a novel therapeutic avenue.
• The identified lead oat peptides can guide the design of new DPP4 inhibitors for diabetes management.
