| | Luminespib Usage And Synthesis |
| Description | Luminespib (AUY-922, NVP-AUY922) 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. Phase 2. | | 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. | | Description | Hsp90 is a molecular chaperone of many different kinases, transcription factors, and hormone receptors involved in signal transduction, cell cycle regulation, and apoptosis. In addition to its important function in normal cell homeostasis, a high affinity form of Hsp90 is prevalent in tumor cells. Hsp90 inhibition has been associated with the degradation of oncogenic client proteins. NVP-AUY922 is a Hsp90 inhibitor (IC50 = 21 nM in a FP binding assay) that prevents the proliferation of a range of human cancer cell lines in vitro with GI50s averaging 9 nM. In a human colon cancer xenograft model, 50 mg/kg NVP-AUY922 inhibits tumor growth by ~50% compared to vehicle controls. Unlike some first generation Hsp90 inhibitors that are quickly glucuronidated, NVP-AUY922 is retained in tumors in vivo when administered at 4 mg/kg i.p. by cassette dosing in tumor-bearing mice. | | Uses | NVP-AUY 922 is a potent inhibitor of heat shock protein 90 (Hsp90) that prevents the proliferation of a range of human cancer cell lines. NVP-AUY 922 has been shown to enhance the radiation sensitivity of tumor cell lines under hypoxia. Potent Hedgehog inhibitor. | | Definition | ChEBI: A monocarboxylic acid amide obtained by formal condensation of the carboxy group of 5-(2,4-dihydroxy-5-isopropylphenyl)-4-[4-(morpholin-4-ylmethyl)phenyl]-1,2-oxazole-3-carboxylic acid with the amino group of ethylamine. | | in vivo | Luminespib (50, 75 mg/kg, i.p.) significantly inhibits tumor growth rate, reducing the mean weights of tumors on day 11 in human tumor xenografts[2]. Luminespib (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]. | | target | HSP90α | | IC 50 | HSP90α: 7.8 nM (IC50); HSP90β: 21 nM (IC50); GRP94: 535 nM (IC50); TRAP-1: 85 nM (IC50) | | References | [1] PAUL A.
