The structure-based design and synthesis of new thioazepinones as ligands f
or Src SH2 protein is presented. From benzothioazepinones, ligands with som
ewhat unspecific binding properties, simpler thioazepinones were designed,
the best ones demonstrated nanomolar affinity for Src SH2. A few of these n
ew ligands were crystallized with the protein and demonstrated a specific b
inding mode with the protein. (C) 2001 Elsevier Science Ltd. All rights res
