Abstract: This paper details an innovative drug development strategy targeting dipeptidyl peptidase-4 (DPP4), which integrates three cutting-edge technologies: virtual screening, molecular docking, and molecular dynamics simulations. This strategy enhances both the efficiency and accuracy of drug development. The study begins with a large compound library, employing advanced algorithms and machine learning tools to efficiently screen for candidate molecules with potential high binding affinity to the DPP4 target, significantly narrowing down the pool of experimental candidates. Subsequently, molecular docking techniques are used to deeply analyze the interaction patterns, energy characteristics, and the role of key amino acid residues between the candidate molecules and the target, successfully identifying lead compounds with high affinity and selectivity. To further validate and optimize, the study incorporates molecular dynamics simulations to dynamically observe the conformational stability, solvation effects, and dynamic binding with the target in a biological environment. This provides scientific evidence for drug design, accelerates the development of DPP4 inhibitors, and opens new prospects for the treatment of diabetes and other metabolic diseases.
