Tenovin-6 Hydrochloride 是 Tenovin-1 的类似物，能抑制二氢乳清酸脱氢酶。它是一种p53转录活性的激活剂，抑制纯化人 SIRT1、SIRT2 和 SIRT3 蛋白脱乙酰酶活性，IC50分别为 21 μM、10 μM 和 67 μM。

Tenovin-6 Hydrochloride is an SIRT1, SIRT2 and HDAC8 inhibitor(IC50s of 21 μM, 10 μM, and 67 μM for SirT1, SirT2, and SirT3, respectively), and is also a potent p53 activator .

Inhibition of SIRT1/2 by Tenovin-6 induced apoptosis in UM cells by activating the expression of tumor suppressor genes such as p53 and elevating reactive oxygen species (ROS).?Tenovin-6 inhibited the growth of UM cells.?Tenovin-6 and vinblastine was synergistic in inducing apoptosis of UM cell line 92.1 and Mel 270.?Furthermore, Tenovin-6 eliminated cancer stem cells in 92.1 and Mel 270 cells.?In conclusion, our findings suggest that Tenovin-6 may be a promising agent to kill UM bulk tumor cells and CSCs[1].tenovin-6 increases microtubule-associated protein 1 light chain 3 (LC3-II) level in diverse cell types in a time- and dose-dependent manner. Mechanistically, the increase of LC3-II by tenovin-6 is caused by inhibition of the classical autophagy pathway via impairing lysosomal function without affecting the fusion between autophagosomes and lysosomes.tenovin-6 activation of p53 is cell type dependent, and tenovin-6 inhibition of autophagy is not dependent on its regulatory functions on p53 and SIRT1[2].
