2021-02-27 19:58 The process of drug discovery involves the identification of molecular candidates, synthesis and test of chemical compounds for their pharmaceutical efficacy. Computer-Aided Drug Design (CADD) is a specialized sub-discipline of rational drug design that uses computational methods to investigate/predict drug-receptor interactions. Quantum mechanics (QM) is an essential tool in CADD research. High-throughput in silico screening of ligand binding (such as docking or QSAR) can significant reduce the time required for compound discovery and optimization.
