Biological Activity

Description AUY922 (NVP-AUY922) is a highly potent inhibitor of HSP90 for HSP90α/β with IC50 of 13 nM /21 nM.
Targets HSP90α HSP90β        
IC50 13 nM 21 nM        

Protocol

Cell experiment: [1]

Cell lines

NCI-N87, SNU-216 and SNU-484 cells

Preparation method

AUY922 was initially dissolved in DMSO at a concentration of 10 mM and aliquots were stored at -20 ℃. Working dilutions were freshly prepared.

Reacting condition

200 nM, 24 h

Applications

AUY922 reduced expression of client proteins. It decreased expression of receptor tyrosine kinases, such as VEGFR1, 2, 3 and PDGFR-α. It also decreased Akt and phospho-Akt in a dose-dependent manner. Besides that, AUY922 treatment resulted in decreased expression of HER-2 in NCI-N87 cells.

Animal experiment : [2]

Animal models

Athymic Nude-nu mice injected with BT-474 breast cancer xenograft

Dosage form

Intravenous acute administration, 30 mg/kg

Application

A significant effect of AUY922 on HSP90-p23 complex dissociation was observed at the 2- and 6-hour time points. From 16 and 24 hours after compound administration, HSP90-p23 complexes reassembled in the BT-474 xenografts. AUY922 also induced phospho-AKT level reduction.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.

1. Inhibition of HSP90 with AUY922 induces synergy in HER2-amplified trastuzumab-resistant breast and gastric cancer. Mol Cancer Ther. 2013 Apr;12(4):509-19. doi: 10.1158/1535-7163.MCT-12-0507. Epub 2013 Feb 8.
Abstract
The mono-therapy of AUY922 in the low nanomolar range potently inhibited proliferation of human gastric and breast cancer cells exhibiting a greater sensitivity to HER2-amplified cells than HER2-negative cells; while the combination of AUY922 and trastuzumab showed synergistic anticancer effect in conditioned trastuzumab-resistant models.

Abstract
AUY922 greatly increased the sensitivity of prostate cancer cells, Myc-CaP and PC3, to radiation and worked synergistically with radiation to increase apoptotic cell death, induce G2-M arrest, affect client protein expression and delay tumor growth.
3. The HSP90 inhibitor NVP-AUY922 potently inhibits non-small cell lung cancer growth. Mol Cancer Ther. 2013 Jun;12(6):890-900. doi: 10.1158/1535-7163.MCT-12-0998. Epub 2013 Mar 14.
Abstract
AUY922 ont only exhibited potent anticancer activity against NSCLC cells with IC50 and IC100 of 100 and 40 nmol/L respectively but also affected expression of genes involved in various cellular functions including decreased dihydrofolate reductase, where exposure to AUY922 stably slowed growth of A549 xenografts and decreased the expression of EGFR protein in H1975 xenografts.

Abstract
NVP-AUY922-AG alone or synergistically with Ara-C exhibited anti-cancer activity against myeloid cell lines and primary AML blasts with significantly less toxicity to normal bone marrow, in which it induced increases in HSP70 expression and depletion of total AKT, IKKα and IKKβ.

Abstract
NVP-AUY922 significantly suppressed the activity of AKT and ERK and potently induced antiproliferation in ESCC cells, which are negatively associated with PETN expression.

Background

AUY922 (NVP-AUY922) is a potent, novel synthetic resorcinylic isoxazole amide inhibitor of heat shock protein 90 (HSP90).[1] It is a small molecular with the formula of C26H31N3O5 and molecular weight of 465.5. It has a much higher affinity for Hsp90 and can be ound to the ATP binding site of Hsp90 at the N-terminal domain.[2] Heat shock protein 90 (HSP90) is a molecular chaperone essential for the stability of key regulators of cell growth and survival. NVP-AUY922 potently inhibits the proliferation of gastric cancer cell lines with with GI50 values of approximately 2 to 40 nmol/L and significantly induces the degradation of growth factor receptors and other client proteins.[3]
