- Fragment hits bind with high energy interactions, so have high ligand efficiency (LE).
- Small libraries of fragments can sample chemical space more widely There are estimated to be ~ 1050 compounds < 500 MW, cf.
~106 fragments < 250 MW.
- Potencies in mM rather than μM range require sensitive biophysical techniques to detect interactions, e.g. X-Ray, NMR, SPR, ITC.
- Millimolar fragments can be converted to nanomolar leads with the support of structure based drug design.
