Fragment-based drug discovery (FBDD) has emerged in the past decade as an alternative approach to traditional lead identification via high-throughput screening (HTS). Unlike HTS, FBDD identifies smaller compounds, the “fragments,” which bind to different parts of a biological target. FBDD has played a role in discovery of 2 approved drugs and at least 30 drugs that are in various stages of clinical development. In response to this evident trend in drug discovery, TargetMol has designed its Fragment Libraries, including a selection of unique fragment subsets: Drug-Fragment Library, High Solubility Fragment Library, and Featured Fragment Library.
