Pimitespib (Jeselhy)
(Redirected from Pimitespib (TAS-116))
Mechanism of action
From the NCI Drug Dictionary: A specific inhibitor of heat shock protein 90 (Hsp90) subtypes alpha and beta, with potential antineoplastic and chemo/radiosensitizing activities. Upon oral administration, Hsp90alpha/beta inhibitor 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.
