Fragmentlibraries Fragment program at ChemDiv is aimed to address another approach in drug discovery – “fragment-based” drug design (FBDD). The immediately available fragment library includes 10,000+ structures. Those were selected from 1.2+ Mio collection and produced as the result of internal design & synthetic effort in consideration of the following guidelines: • Widely accepted Astex Rule of Three[1] (MW ≤ 300, H-bond donors ≤ 3, H-bond acceptors ≤ 3, cLogP ≤ 3) • The tagged fragments may contain only C, H, N, O, S, P, F, Cl, and Br atoms • The tagged fragments must be chemically feasible for follow up linking and/or expansion • The tagged fragments comply with internal medicinal chemistry filters (this way undesirable moieties, such as Michael acceptors, can be removed upfront) • Add-ons of structures with fragment-“friendly” features, such as: - NMR screening compatibility (chemical shifts of protons to be in the 0 – 12 range evenly; possession of both alkyl & aromatic protons, or “marker atoms”, e.g. F) - X-ray screening compatibility (heavy atoms) As with any other “classical” small molecules library, the data base with immediately available fragments can be provided (as MDL structure-data files (SDfiles) or ISIS Database (db) files) for follow up selection and ordering. The fragments can be dispensed in mg or micromolar amounts and delivered in a variety of formats (plates or vials, as dry powders or DMSO solutions).
