Biochem/physiol Actions

High-affinity, potent and selective heat shock protein 90 (HSP90α/β) inhibitor with anti-cancer efficacy in cultures and in vivo.



NVP-AUY922 (Luminespib; VER-52296) is a high-affinity (HSP90β Kd = 1.7 nM), potent and selective heat shock protein 90 inhibitor (HSP90α/β Ki = 9.0/8.2 nM, HSP90α/β IC50 = 7.8/21 nM) that exhibits anti-proliferation potency in cancer cultures (GI50 from 2 to 40 nM among 29 cancer lines) and anti-tumor efficacy in vivo (50-75 mg/kg/day i.p.) by inducing cancer cells G1-G2 arrest and apoptosis.

The heat shock protein 90 inhibitor, luminespib, has demonstrated potent preclinical activity against numerous cancers. However, clinical translation has been impeded by dose-limiting toxicities that have necessitated dosing schedules which have reduced therapeutic efficacy. As such, luminespib is a prime

We describe the biological properties of NVP-AUY922, a novel resorcinylic isoxazole amide heat shock protein 90 (HSP90) inhibitor. NVP-AUY922 potently inhibits HSP90 (K(d) = 1.7 nmol/L) and proliferation of human tumor cells with GI(50) values of approximately 2 to 40

Heat shock protein 90 (HSP90) is a key component of a multichaperone complex involved in the post-translational folding of a large number of client proteins, many of which play essential roles in tumorigenesis. HSP90 has emerged in recent years as
