A blog founded by Teddy Zartler and run by Dan Erlanson for Fragment-based Drug Discovery devotees to discuss non-confidential issues regarding fragments.
Serendipity in fragments: A screen for hits against the hard-to-drug, plasma membrane-recruiting Pleckstrin Homology Domain finds an unusually reactive lysine, and a covalent hit against BTK

Watch out for X-ray structures that assume every protein has a ligand. A new analysis suggests one-third should show partial binding. Just one-tenth in the PDB actually do:

GPCRs, NMR, hit optimization, platform development, covalent drugs, direct-to-biology, computational screening, molecular glues, and more
A practical metric from @VividionRxto to help weed out nonspecific, generally-reactive covalent ligands:
Ligand reactivity efficiency (LRE)

3D fragment hit rates are lower, but perhaps advancement goes faster. A shapely scaffold yields an impressive hit for the histamine H1 receptor.
