Computer-Aided Drug Design

Computer aided drug design (CADD, or in silico screening) has become a powerful technique in the process of drug development and drug discovery, to facilitate the drug design process thereby minimizing time and costs. The general process of in silico drug discovery includes identification of therapeutic target, cause and mechanisms revealing, generation of small compounds library, docking and scoring, pharmacokinetic studies, and lead compound generation. There are two common types of computer-aided drug design (CADD) approaches, structure based drug design (SBDD) and ligand based drug design (LBDD). Protheragen has set up an expert team of structure biologists, biophysicists and computational scientists for discovery of new chemical entities.
