Drug discovery and development is a time consuming and expensive process., taking about 10 years and huge cost. Several candidates that enter clinical trials fail because of several reasons. Computer assisted drug design can speed up the process, reduce surprises and predict the properties, thereby reduce the cost of R&D. The course will cover structure and Ligand and Structure based design, molecular modeling, drug likeness properties, QSAR and pharmacokinetic and dynamics using several softwares that are freely available.
