B, crystallographic complex of ganetespib in the Hsp90 N-terminal.

C, hydrogen bond interactions between ganetespib with amino acid residues in the Hsp90 N-terminal ATP-binding pocket.

Synta Pharmaceuticals  has opened a ClinicalTrials.gov listing for their much discussed GALAXY-2 phase 3 trial of their HSP90 inhibitor ganetespib in second-line non-small cell lung cancer (NSCLC), in combination with docetaxel. For the moment at least, the phase 2b GALAXY-1 trial is still listed as enrolling patients, but that would be expected to complete soon.

  2. Have you ever considered about including a little bit more than just your articles? I mean, what you say is fundamental and all. Nevertheless imagine if you added some great visuals or video clips to give your posts more, “pop”! Your content is excellent but with pics and clips, this blog could undeniably be one of the greatest in its field. Fantastic blog!|
