Product Description
Information
Luminespib (NVP-AUY922) 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 bi In vitro
NVP-AUY922 inhibits proliferation of various human cancer cell lines in vitro, with an average GI50 of 9 nM. 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. 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.
In vivo
Treatment with NVP-AUY922 causes a robust antitumor response and inhibits p-Akt and VEGF expression in an HSC-2 xenograft model. In BT474, NVP-AUY922 shows complete loss of ERBB2 and substantial depletion of ERα, in addition to reductions in CDK4 and phospho-ERK1/2. Cell Data
