Description

AUY-922, also known as Luminespib, NVP-AUY922, VER52296, is a derivative of 4, 5-diarylisoxazole and a third-generation heat shock protein 90 (Hsp90) inhibitor with potential antineoplastic activity. Hsp90 inhibitor AUY-922 has been shown to bind with high affinity to and inhibit Hsp90, resulting in the proteasomal degradation of oncogenic client proteins; the inhibition of cell proliferation; and the elevation of heat shock protein 72 (Hsp72) in a wide range of human tumor cell lines.

How to use

In Vitro:

AUY-922 is a potent and selective HSP90 inhibitor, with IC50s and Kis of 21 ± 16, 8.2 ± 0.7 nM against HSP90β and of 7.8 ± 1.8, 9.0 ± 5.0 nM for HSP90α. AUY-922 shows weak activity against GRP94 and TRAP-1 wich IC50s of 535 ± 51 nM (Ki, 108 nM) and 85 ± 8 nM (Ki, 53 nM), respectively. AUY-922 exhibits inhibitory effect on proliferation of various human tumor cell lines (2.3-49.6 nM), induces cell cycle arrest and apoptosis and depletes client proteins in human cancer cells (80 nM). AUY-922 (100 nM) significantly reduces CD40L fibroblast-induced changes in immunophenotype and STAT3 signaling but with no effect on the viability of chronic lymphocytic leukemia (CLL) cells. AUY-922 (500 nM) in combination with NSC 118218 more effectively induces apoptosis in cells in co-culture than either drug alone, and overcomes fibroblast-derived resistance to Hsp90 inhibitor. AUY-922 shows great inhibition of pancreatic cancer cells with IC50 of at 10 nM. AUY-922 (10 nM) reduces the expression and the epidermal growth factor (EGF)-mediated activation of EGFR and substantially disrupts EGF signaling in terms of diminishing downstream phosphorylation of ERKThr202/Tyr204. AUY-922 (10 nM) significantly blocks pancreatic cancer cell migration and invasion both in the absence and presence of EGF.

In Vivo:

AUY-922 (50, 75 mg/kg, i.p.) significantly inhibits tumor growth rate, reducing the mean weights of tumors on day 11 in human tumor xenografts. AUY-922 (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.
