Description: NSC145366 is an inhibitor of Hsp90 activities which targets the Hsp90 C-terminal domain to induce allosteric inhibition and selective client downregulation. NSC145366 increases Hsp90 oligomerization resulting in allosteric inhibition of NTD ATPase activity (IC50=119μM) but does not compete with NTD or CTD-ATP binding.
