NVP-AUY922 is a highly potent HSP90 inhibitor with IC50 of 13 nM/21 nM for for HSP90α/β, respectively, and has weaker potency against the HSP90 family members GRP94 and TRAP-1.

IC50 & Target

IC50: 13 nM (HSP90α), 21 nM (HSP90β)

In Vitro

AUY922 significantly attenuates changes in immunophenotype and signal transducer and activator of transcription 3 (STAT3) signaling induced by CD40L-fibroblast co-culture but has no effect on the viability of CLL cells. AUY922 in combination with fludarabine is significantly more effective at inducing apoptosis in cells in co-culture than either drug alone, an effect that is irrespective of ATM/TP53 dysfunction[1]. NVP-AUY922 binds to the NH2-terminal nucleotide site in HSP90. NVP-AUY922 inhibits HSP90 family members GRP94 and TRAP-1 with IC50 values of 535 nM and 85 nM, respectively. NVP-AUY922 induces marked accumulation in either GEC1 or G1 plus G2-M phases in most cell lines[2]. NVP-AUY922 shows great inhibition of pancreatic cancer cells with IC50 of at 10 nM. VP-AUY922 (10 nM for 20 h) reduces the expression and the epidermal growth factor (EGF)-mediated (40 ng/mL) activation of EGFR and substantially disrupts EGF signaling in terms of diminishing downstream phosphorylation of ERKThr202/Tyr204. NVP-AUY922 (10 nM) significantly blocks pancreatic cancer cell migration and invasion both in the absence and presence of EGF[3].

In Vivo

NVP-AUY922 (50, 75 mg/kg, i.p.) significantly inhibits tumor growth rate, reducing the mean weights of tumors on day 11[2]. NVP-AUY922 (50 mg/kg/week, 3×25 mg/kg/week) significantly reduces tumor growth rates and lowers tumor weights in the L3.6pl pancreatic cancer cell-bearing mice model[3].

Cell Assay

Cell lines are grown in DMEM/10% FCS, 2 mM glutamine, and nonessential amino acids in a humidified atmosphere of 5% CO2 in air as described. All lines are free of Mycoplasma. Cell proliferation is determined using the sulforhodamine B (SRB) assay for tumor cells and prostate epithelial cells, the WST-1 assay for MCF10A and HB119, or an alkaline phosphatase assay for HUVEC and HDMEC. GI50 is the compound concentration inhibiting cell proliferation by 50% compared with vehicle controls. Cell cycle analysis is as described. Active caspase-3/7 is measured using a homogenous caspase assay kit.

Animal Administration

NVP-AUY922 is dissolved in DMSO and diluted in sterile saline/Tween 20.

For efficacy studies, human tumor xenografts are established s.c. in athymic mice. WM266.4 cells are also injected i.v. to generate experimental lung metastases and PC3LN3 prostate carcinoma cells are implanted into the prostates of male mice. Dosing with NVP-AUY922 commences when tumors are well established using schedules described. Tumor growth is monitored and at study end samples are harvested for analysis.
