AB  - In the last decade the heat shock protein 90 (Hsp90) has emerged as a major
      therapeutic target and many efforts have been dedicated to the discovery of Hsp90
      inhibitors as new potent anticancer agents. Here we report the identification of 
      a novel class of Hsp90 inhibitors by means of a biophysical FAXS-NMR based
      screening of a library of fragments. The use of X-ray structure information
      combined with modeling studies enabled the fragment evolution of the initial
      triazoloquinazoline hit to a class of compounds with nanomolar potency and
      drug-like properties suited for further lead optimization.
