Fragment-based drug discovery truly unlocks synergy of parts by finding highly diverse and rather small ligands that ever increase their binding efficiency and maximize bioavailability once joined in a new molecule.

FBDD is also great compliment to any HTS campaign for enzyme targets as it aids early hit discovery and optimization when data from both screening approaches is compared. Fragment library screen is always target specific in fit being comprised of minimum pharmacophores. FBDD “combines the empiricism of random screening with the rationality of structure-based design”. If available, any structural parts match between HST and FBDD hits is good foundation for preliminary SAR.

TimTec Fragment-Based Library, FBL gathers structurally diverse ligands with low molecular weight and high solubility.

Fragment-Based Drug Discovery has been gaining more and more attention since mid 1990s, the year when the SAR-by-MNMR technology is developed at Abbott. Number of most recent technological advancements makes FBDD approachable part of HTS campaigns.

Small in size FBDD libraries furnish vast chemical space design combinations in building drugs from small molecular pieces. Structure-based approach can be applied very early in fragments optimization to decrease and/or eliminate undesirable structural characteristics to boost in vivo safety and minimize number of synthesized lead candidates.

FBDD complementary benefits to HTS:

 

  • Oftentimes HTS falls short of generating leads for selected challenging targets

  • Combinations of fragments cover greater chemical diversity space multiplying optimization options

  • FBDD is an economical precursor to HTS being able to identify compound-analogs with desirable “active” fragments

  • Faster aggregation of SAR data for hit-to-lead development
