Fragment-based drug discovery is now widely adopted for lead generation in the pharmaceutical industry. However, fragment screening collections are often predominantly populated with flat, 2D molecules. Herein, we describe a workflow for the design and synthesis of 56 3D disubstituted pyrrolidine and piperidine fragments that occupy under-represented areas of fragment space (as demonstrated by a principal moments of inertia (PMI) analysis). A key, and unique, underpinning design feature of this fragment collection is that assessment of fragment shape and conformational diversity (by considering conformations up to 1.5 kcal mol?1 above the energy of the global minimum energy conformer) is carried out prior to synthesis and is also used to select targets for synthesis. The 3D fragments were designed to contain suitable synthetic handles for future fragment elaboration. Finally, by comparing our 3D fragments with six commercial libraries, it is clear that our collection has high three-dimensionality and shape diversity.
Bridged 5,6,7,8-tetrahydro-1,6-naphthyridines, analogues of huperzine A: Synthesis, modelling studies and evaluation as inhibitors of acetylcholinesterase

Derivatives of 6,8-bridged 5,6,7,8-tetrahydro-1,6-naphthyrid-ines, designed as analogues of huperzine A, were synthe-sised and evaluated as inhibitors of acetylcholinesterase. In a first approach, C3-bridged naphthyridines were constructed by internal nucleophilic aromatic substitution of 2-chloro-3-(1-piperidinylmethyl)pyridine precursors containing a 3-CO 2Me group on the 1-piperidinyl ring moiety. Alternatively, ring-closing metathesis on 6,8-diallyl-substituted tetrahydro-1,6-naphthyridines was applied to construct an unsaturated C4 bridge. Some of the target compounds showed inhibition of acetylcholinesterase but lower than that of huperzine A. The relative order of inhibition activities could be rationalised by comparative docking simulation studies on the basis of the known crystal structure of the ace-tylcholinesterase-huperzine A complex.
