Sirtinol是SIRT的抑制剂,在MCF-7细胞中的IC50值为48.6 μM(24 h)和43.5 μM(48 h)[1]。
Sirtinol以浓度和时间依赖的方式显著抑制MCF-7细胞的生长。同时,sirtinol也显著减少SIRT1的表达水平,从而诱导p53的乙酰化。据报道,sirtinol减少细胞周期调控蛋白的表达,如cyclin B1、cyclin D1、CDK2和CDK6,从而诱导G1期停滞,表明细胞凋亡。而且,sirtinol也诱导MCF-7细胞的自噬。其它的体外实验表明,sirtinol抑制SIRT2(氨基酸18–340),IC50值为45 μM,而在50和100 μM时对HDAC1没有抑制作用[1,2]。

激酶实验 [1]: | |
人源Sirt2酶体外活性抑制实验 |
将1.5 μg重组蛋白GST-Sirt2(氨基酸18 ~ 340)置于50 μL实验缓冲液(50 mM Tris-HCl,pH 8.8,4 mM MgCl2,0.2 mM二硫苏糖醇,不同浓度的Sirtinol,50 μM NAD,以及通过酸萃取法得到的氚标记的乙酰化HeLa细胞组蛋白 (1000 cpm))中,于30 °C下,孵育2小时。通过闪烁计数检测可溶于乙酸乙酯的[3H]乙酸,测定HDAC活性。 |
细胞实验 [2]: | |
细胞系 |
LNCaP、22Rv1、DU145和PC3细胞 |
制备方法 |
在DMSO中的溶解度大于10 mM。若配制更高浓度的溶液,一般步骤如下:请将试管置于37 °C加热10分钟和/或将其置于超声波浴中震荡一段时间。原液于-20 °C可放置数月。 |
反应条件 |
30或120 μM;24或48小时 |
实验结果 |
给予Sirtinol(30和120 μM)。于24或48小时后,Sirtinol显著降低所有PCa细胞系的生长与存活能力。 |
动物实验 [3]: | |
动物模型 |
雄性SD大鼠创伤出血模型 |
给药剂量 |
1 mg/kg;静脉注射 |
实验结果 |
在雄性SD大鼠创伤出血模型中,Sirtinol (1 mg/kg) 减少促炎细胞因子的产生并防止肝损伤。 |
其它注意事项 |
请于室内测试所有化合物的溶解度。虽然化合物的实际溶解度可能与其理论值略有不同,但仍处于实验系统误差的允许范围内。 |
