Introduction into Fragment Based Drug Discovery

Fragment-based drug discovery (FBDD) is a method used for finding hit compounds as one strategy of hit identification in the drug discovery process. Fragments are small molecules with a low molecular weight, smaller than lead molecules or druglike molecules. The FBDD technology is based on identifying small chemical fragments, which bind to the biological target and which are then optimized into leadlike and druglike molecules. In contrast to high throughput screening (HTS) where libraries of millions of compounds with molecular weights of around 500 Da are tested and nanomolar binding affinities are found, fragments come from much smaller libraries and show weaker binding affinities. They still make good starting points for drug discovery.
In contrast to hit identification by HTS the conditions for FBDD are different. A smaller fragment library, fragment hits with weaker affinities, the need for guidance by structure information and the use of compound metrics in the optimization are central elements of FBDD. The webinar will give insight into this technology and will show how FBDD can be successfully applied for the identification of novel and potent lead compounds
