Pimitespib (TAS-116) is a novel, potent and selective inhibitor of heat shock protein 90 (Hsp90) subtypes alpha and beta [HSP90α/HSP90β] with anticancer activity. It inhibits HSP90α/HSP90β with Kis of 34.7 nM and 21.3 nM, respectively. It has potential antineoplastic and chemo/radiosensitizing activities. TAS-116 specifically binds to and inhibits the activity of Hsp90 alpha and beta; this results in the proteasomal degradation of oncogenic client proteins, which inhibits client protein dependent-signaling, induces apoptosis, and inhibits the proliferation of cells overexpressing HSP90alpha/beta.
