auy 922

Luminespib (VER-52296) 是一种 HSP90 抑制剂，抑制 HSP90α 和 HSP90β (IC50=7.8 21 nM)。Luminespib 具有抗肿瘤活性，用于头颈部肿瘤等的研究。

Luminespib, also known as AUY-922, 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 AUY922 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.

HSP90-IN-11 是 HSP90 的有效抑制剂，诱导亚 G1 期群体的显着积累。 HSP90-IN-11 具有与 AUY-922 (Luminespib) 相当的有效 HSP90α 抑制作用。在 CRC 和 NSCLC 细胞中，HSP90-IN-11 具有显着的抗增殖活性，在两位数 nM 范围内。HSP90-IN-11 能够快速降解 NSCLC 细胞中客户蛋白 EGFR 和 Akt 。
