Biological Activity

Description Luminespib (AUY-922, NVP-AUY922, VER-52296) is a highly potent HSP90 inhibitor for HSP90α/β with IC50 of 13 nM /21 nM in cell-free assays, weaker potency against the HSP90 family members GRP94 and TRAP-1, exhibits the tightest binding of any small-molecule HSP90 ligand. Luminespib (AUY-922, NVP-AUY922) effectively downregulates and destabilizes the IGF-1Rβ protein and results in growth inhibition, autophagy and apoptosis. Phase 2.

13 nM 21 nM
In vitro NVP-AUY922 inhibits proliferation of various human cancer cell lines in vitro, with an average GI50 of 9 nM. [1] The IC50 values of NVP-AUY922 fall in the range of 2 to 40 nM in these gastric cancer cell lines. IC50 value for the BEAS-2B cells is 28.49 nM. Treatment with NVP-AUY922 does not influence the expression of HSP90, but expression of HSP70 gets elevated by NVP-AUY922 treatment. NVP-AUY922 increases the binding of HSP70 to HSP90. NVP-AUY922 causes p23 dissociation from the HSP90 complex and can then recruit HSP70 to the HSP90 complex. [1] After the treatment with NVP-AUY922, expression of receptor tyrosine kinases including VEGFR1, 2, 3 and PDGFRɑ is decreased. A decrease is also noticed in the expression of Akt and phospho-Akt. Meanwhile, treatment with NVP-AUY922 causes decreased expression of HER-2 in NCI-N87 cells. NVP-AUY922 treatment results in binding of HSP90 to client proteins and setting them up as targets for degradation by the proteasome. NVP-AUY922 can influence cell growth by affecting multiple signaling pathways. In addition, treatment with the proteasome inhibitor, MG132, restores expression of thymidylate synthase, which is decreased by NVP-AUY922. NVP-AUY922 increases the expression of cleaved caspase-3 leading to apoptosis in HSC-2 cells.[1]
In vivo Treatment with NVP-AUY922 causes a robust antitumor response and inhibits p-Akt and VEGF expression in an HSC-2 xenograft model. [2] In BT474, NVP-AUY922 shows complete loss of ERBB2 and substantial depletion of ERα, in addition to reductions in CDK4 and phospho-ERK1/2. [3]

Protocol (from reference)

Kinase Assay:[3]
  • Kinase assay

    NVP-AUY922 is dissolved in DMSO at a concentration of 10 mM. NVP-AUY922 is assessed against HSP90α, HSP90β, GRP94, TRAP-1, HSP72, and topoisomerase II. Profiling against a panel of kinases has been carried out and screening against a panel of additional enzymes and receptors is performed at Cerep.

Cell Assay:[1]
  • Cell lines

    Human gastric cancer cells NCI-N87

  • Concentrations

    1 μM

  • Incubation Time

    3 days

  • Method

    Human gastric cancer cells NCI-N87 (5-7 ×103 in 50 μL/well) are seeded in 96-well plates and incubated at 37 °C for 24 hours, followed by NVP-AUY922 treatment for 1-3 days at 37 °C. After treatment, the cells are assayed by MTT method and analyzed by microplate reader.

Animal Study:[3]
  • Animal Models

    Female NCr athymic mice bearing WM266.4 human melanoma xenografts

  • Dosages

    50 mg/kg

  • Administration

    Administered via i.v. or i.p.
