3D-Rich Fragments

Explore new chemical space with access to 3D-rich, covalent, and enantiopair fragments

Covalent Fragments

LCC’s Parallel Synthesis Laboratory is co-located with our in-stock synthons, meaning we can efficiently synthesise sets of covalent fragments. With a focus on chirally-pure material, we specialise in providing sets of enantiomers with absolute stereochemistry determined. Racemic and achiral material is also available.

Novel, 3D-rich, diverse, in-stock fragment library

  • 1,000 member Ro3 compliant fragment library, with >100 fluorinated fragments
  • Predominantly 3D-rich, with a balance of sp3-sp2 character, and a low number of rotatable bonds (saturated cyclic core scaffolds)
  • Good property space - measured and predicted water solubility, predicted membrane permeability, 3D-character and sphere-like molecules
  • Fragments (+ near-neighbour analogues) available for rapid follow-up

Available pre-plated in DMSO solution, or custom plating in solid form

Introducing LCC's 3DiscoveryTM platform


Move from Ro3 (fragment-like) to Ro4 (lead-like) space using LCC's platform, which has been designed through combining our 3D-rich fragment library with computational expertise and parallel synthesis capabilities.
