Additionnal Information
Pimitespib (TAS-116) is a novel, small-molecule HSP90 inhibitor which inhibits geldanamycin-FITC binding to HSP90 proteins with Ki values of 34.7 nmol/L, 21.3 nmol/L, >50,000 nmol/L, and >50,000 nmol/L for HSP90α, HSP90β, GRP94, and TRAP1, respectively. Furthermore, TAS-116 does not inhibit other ATPases such as HSP70 (IC50 >200 μmol/L) .

3 years -20°C powder

Chemical Information

Pimitespib

Tas-116 is pimitespib is a specific inhibitor of heat shock protein 90 (Hsp90) subtypes alpha and beta, with potential antineoplastic and chemo/radiosensitizing activities. Upon oral administration, pimitespib 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.
