Identification of Novel HSP90α/β Isoform Selective Inhibitors Using Structure-Based Drug Design. Demonstration of Potential Utility in Treating CNS Disorders such as Huntington’s Disease
toxicity. Improved tolerability profiles may enable the use of HSP90α/β selective inhibitors in treating chronic neurodegenerative indications such as Huntington’sdisease (HD). A potent, selective, orally available HSP90α/β inhibitor was identified (compound 31) that crosses the blood–brain barrier. Compound 31 demonstrated proof of concept by successfully reducing brain Htt levels following oral dosing
