Drug Targeting through Molecular Dynamic Simulation Studies

The MD simulation approach is developed to better understand the structure-to-function behavior of the protein-ligand complex. MD simulation is a vital approach for understanding the dynamic behavior of many systems such as physical, chemical, and biological processes. MD simulation computes the energy of interacting atoms as well as their dynamic nature using Newton's second equation of motion. MD simulation is a molecular mechanics-based modeling technology that is commonly utilized in the pharmaceutical industry to create innovative drug systems. The structural coordinates of the targeted bacteria are obtained via comparative homology modeling, which is a prerequisite for comprehensive docking and simulation techniques. The goal of the docking study is to examine inhibitory mechanisms based on atomic interactions, which provided insight into the specific drug design. Several natural and synthetic inhibitors have been developed to mimic the enzyme's natural substrate. The docking procedure provides valuable information about the active residues, which helps to understand the stability and potency of the protein-ligand complex. The docked and undocked complexes are successfully modified in molecular dynamic simulations that looked at their catalytic activity. The investigations of protein-ligand interactions will point researchers in a new route for developing more mechanism-based competitive inhibitors to combat pathogen resistance.
