  • NVP-AUY922 potently inhibited HSP90 with IC50 values of 7.8 nM and 21 nM, and Ki values of 9 nM and 8.2 nM for HSP90α and HSP90β, respectively. NVP-AUY922 showed a very high binding affinity to HSP90β with a Kd of 1.7 nM. NVP-AUY922 inhibited the proliferation of human tumor cells in vitro with GI50 values of approximately 2 to 40 nM, inducing G1-G2 arrest and apoptosis. Human endothelial cells were very sensitive to NVP-AUY922 with GI50s of 2.5-3.9 nM. NVP-AUY922 also exhibited potent antitumor efficacy in human tumor xenografts including BT474 breast, A2780 ovarian, U87MG glioblastoma, PC3 prostate, and WM266.4 melanoma. Eccles, S.A., et al. "NVP-AUY922: a novel heat shock protein 90 inhibitor active against xenograft tumor growth, angiogenesis, and metastasis." Cancer Res. 68: 2850-2860 (2008).
  • NVP-AUY922 showed impressive synergistic inhibitory effect with histone deacetylase inhibitors, melphalan, doxorubicin, NVP-LBH589 (Panobinostat), and suberoylanilide hydroxamic acid (SAHA, Vorinostat) on the growth of multiple myeloma cell lines and primary myeloma cells.

Haematol. 84: 337-344 (2010).
  • NVP-AUY922 potently inhibited the proliferation of human breast cancer cell lines with GI50 values in the range of 3 to 126 nM. NVP-AUY922 induced proliferative inhibition concordant with HSP70 upregulation and client protein depletion. Significant growth inhibition of BT-474 tumor and good tolerability were observed in athymic mice when NVP-AUY922 was administered once per week. Therapeutic effects were also concurrent with changes in pharmacodynamic markers, including HSP90-p23 dissociation, decreases in ERBB2 and P-AKT, and increased HSP70 protein levels.

  • Prostate-specific antigen (PSA) may serve as a sensitive biomarker of Hsp90 inhibition. Oikonomopoulou, K., et al. "Evaluation of prostate-specific antigen as a novel biomarker of Hsp90 inhibition." Clin. Biochem. 42: 1705-1712 (2009).
  • 89Zr-bevacizumab PET was concordant with the antiangiogenic response and direct antitumor effects after NVP-AUY922 treatment. It provided a noninvasive tool to monitor tumor VEGF levels. Nagengast, W.B., et al. "89Zr-bevacizumab PET of early antiangiogenic tumor response to treatment with HSP90 inhibitor NVP-AUY922." J. Nucl. Med. 51: 761-767 (2010).
  • NVP-AUY922 effectively reduces human epidermal growth factor receptor-2 (HER2), which can be monitored with 89Zr-trastuzumab PET in vivo non-invasively. It might serve as an early biomarker for HSP90 inhibition in HER2 positive metastatic breast cancer patients. Oude Munnink, T.H., et al. "89Zr-trastuzumab PET visualises HER2 downregulation by the HSP90 inhibitor NVP-AUY922 in a human tumour xenograft." Eur. J. Cancer 46: 678-684 (2010).
  • Hsp90 inhibitors NVP-AUY922 and NVP-BEP800 enhanced radiosensitivity in four tumor cell lines tested (A549, GaMG, HT 1080, and SNB19). Stingl, L., et al. "Novel HSP90 inhibitors, NVP-AUY922 and NVP-BEP800, radiosensitise tumour cells through cell-cycle impairment, increased DNA damage and repair protraction." Br. J. Cancer 102: 1578-1591 (2010).
