生物活性 Cambinol is a SIRT1 and SIRT2 inhibitor with IC50 values of 56 μM and 59 μM, respectively. Cambinol is a potent brain penetrant neutral sphingomyelinase (N-SMase) inhibitor (exosome inhibitor)[1-2].
In Vitro Cambinol inhibits NAD-dependent deacetylase activity of human SIRT1 and SIRT2. Inhibition of SIRT1 activity with cambinol during genotoxic stress leads to hyperacetylation of key stress response proteins and promotes cell cycle arrest. Treatment of BCL6-expressing Burkitt lymphoma cells with cambinol as a single agent induces apoptosis, which is accompanied by hyperacetylation of BCL6 and p53. Cambinol has only weak inhibitory activity against SIRT5 (42% inhibition at 300 μM) and no activity against SIRT3[1].
In Vivo Cambinol is well tolerated in mice (100 mg/kg) and inhibits growth of Burkitt lymphoma xenografts. No significant weight loss occurs in cambinol-treated animals relative to controls. Inhibitors of NAD-dependent deacetylases may constitute novel anticancer agents[1].

靶点 Sirtuin
动物实验 Mice: Cambinolat the dose of 100 mg/kg, or vehicle are administered i.v. through tail vein injection or i.p. daily from day 5 to 19 (five injections per week). The dose of 100 mg/kg cambinol is the highest dose that could be administered as a single i.v. injection due to limited solubility of the drug. Tumor size is measured thrice a week using caliper and the tumor volumes are calculated[1].
细胞实验 .The reporter construct with or without varying amounts of GAL4-BCL6 expression plasmid are introduced into NCI-H460 cells using calcium phosphate method. A plasmid containing cytomegalovirus (CMV)-driven β-galactosidase reporter (50 ng) is cotransfected to control for transfection efficiency. Sixteen hours after transfection, cells are treated with 100 μM cambinol of DMSO (control) for 24 hours and the luciferase and β-galactosidase activity is measured[1].

生物活性 Tenovin-6 是水溶的 SIRT1、SIRT2 抑制剂,p53 的激活剂,同时能抑制 HDAC8 的活性,对 SirT1 peptide deacetylase,SirT2 和 SirT3 的 IC50 值分别为 21 μM,10 μM 和 67 μM。[1-4]
IC50 SIRT2:10 μM ; SIRT1:21 μM ; SIRT3:67 μM [1-4]
In Vitro Tenovin-6(0至15μM)剂量依赖性地增加不同细胞类型中LC3-II的水平,并且该增加是ATG5/7依赖性的。在存在或不存在Torin 1的情况下,Tenovin-6处理也增加了自噬囊泡的数量和强度,并且防止了Torin 1诱导的SQSTM1/p62降解。 Tenovin-6影响自溶酶体的酸化并损害溶酶体的水解活性,但不影响自噬体和溶酶体之间的融合。 tenovin-6抑制自噬与p53活化无关,敲除或敲除对SIRT1/2的抑制作用不能模拟tenovin-6对LC3B积累的影响[2]。 Tenovin-6抑制酿酒酵母培养物的生长,IC50为30μM,对酵母的毒性大于水溶性较低的tenovin-1。 Tenovin-6迅速增加MCF-7细胞中内源性K382-Ac p53的水平[1]。Tenovin-6(0,1,2.5,5或10μM)在所有OCI-Ly1,DHL-10,U2932,RIVA,HBL1和OCI-Ly10细胞系中以剂量和时间依赖性方式有效抑制细胞增殖。 Tenovin-6通过抑制经典自噬途径而不激活p53,一致地增加DLBCL细胞系中的LC3B-II水平,并且该增加不依赖于SIRT1/2/3和p53。 Tenovin-6通过外在细胞死亡途径诱导细胞凋亡[3]。 Tenovin-6抑制UM细胞的生长,对于92.1,Mel 270,Omm 1和Omm 2.3细胞,IC50分别为12.8μM,11.0μM,14.58μM和9.62μM[4]。
In Vivo Tenovin-6(50 mg/kg,ip)抑制小鼠肿瘤的生长[1]。
