In this account , we present two innovative tools ( which we are prepared to share with academic institutions ) facilitating computational tasks commonly utilized in drug discovery and development : ( 1 ) the VirtualDesignLab estimates the binding affinity of small molecules by simulating and quantifying their binding to the three - dimensional structure of a target protein ; and ( 2 ) the MD Client launches molecular dynamics simulations aimed at exploring the time - dependent stability of ligand - protein complexes and provides residue - based interaction energies .
