基本信息

产品描述

Inauhzin是具有细胞透性的SIRT1抑制剂，IC50为0.7-2 μM，可通过抑制SIRT1脱乙酰活性重新激活p53。

靶点（IC50 & Targe）

SIRT1,p53

体外研究

Inauhzin (INZ) is a potent p53 activator and mediates p53-dependent cytotoxicity. INZ inhibits cell proliferation by triggering both apoptosis and senescence in p53-containning cells, though it predominantly induces p53-dependent apoptosis. INZ is able to prevent p53 from MDM2-mediated ubiquitylation and proteasomal degradation and protects p53 without either directly inhibiting MDM2 activity towards p53 or interfering with MDMX/MDM2–p53 interaction. INZ induces acetylation of p53, but not tubulin, in cells[1]. Inauhzin is a (sub)micromolar SIRT1i selective over SIRT2/3[2].

体内研究

Inauhzin (INZ) has good tumour tissue penetration and is able to inhibit tumour growth by inducing p53[1].
