Vorinostat (SAHA, MK0683,AbMole,M1780) 是一种广谱的泛组蛋白去乙酰化酶抑制剂(HDACi)。其化学结构属于丁二酰亚胺羟肟酸类化合物,能够通过直接与HDACs结合并抑制其活性,增加乙酰化组蛋白的积累,从而调节细胞中的基因表达,并影响多个信号通路。此外,Vorinostat(MK0683)还具有细胞周期阻滞、凋亡、抑制血管生成等生物活性。研究表明,Vorinostat还可双向调控应激反应基因的表达(如sod-3、hsp-16.2、skn-1等),Vorinostat在低浓度时上调上述基因的表达,而在高浓度(10μM)时则呈现抑制或中性效应,显示出剂量依赖性的表观遗传调控特性[1]。Vorinostat还可通过降低Akt信号通路的表达水平,诱导细胞周期阻滞和程序性死亡[2]。此外,Vorinostat还可下调多种表观遗传调控酶(如EZH2、SUV39H1/2、DOT1L等)的表达,说明其对表观遗传调控网络具有广泛的影响[3]。在科研应用中,Vorinostat (SAHA)展现出多方面的潜力。首先Vorinostat可抑制多种肿瘤细胞的增殖,例如结肠癌细胞(HCT116、HT29)[4]、胰腺癌细胞(AsPC-1)[5]、肝癌细胞(LCL-PI 11)[5]、头颈部鳞癌(HNSCC)等[6]。Vorinostat还可用于抑制寄生虫,其机制同样涉及原虫细胞中HDAC的抑制[7]。值得注意的是,组织转谷氨酰胺酶(TG2)的活性状态会影响细胞对Vorinostat的敏感性。研究发现TG2活性的抑制可增强Vorinostat的抗增殖效应,而TG2过表达则导致细胞耐受性的获得,提示TG2是Vorinostat耐受机制中的关键靶点[8]。在神经保护领域,Vorinostat可逆转β淀粉样蛋白(Amyloid β Protein)诱导的神经损伤,该生物学活性涉及对AKT-MDM2-p53通路的调控[9]AbMole为全球科研客户提供高纯度、高生物活性的抑制剂、细胞因子、人源单抗、天然产物、荧光染料、多肽、靶点蛋白、化合物库、抗生素等科研试剂,全球大量文献专利引用。

科研人员在该文章中探究了Vorinostat对小细胞肺癌(SCLC)的抑制作用及联合抑制方案的开发。研究通过体外(H209、H146 细胞系)和体内(H209 异种移植裸鼠)实验,证实 Vorinostat(HDAC 抑制剂)与顺铂(Cisplatin)联合或与Etoposide (VP-16-213) 联合使用时,能比单一处理组更显著地抑制肿瘤细胞的活力、并诱导凋亡(激活 caspase-3、促进 PARP 裂解),以及诱导肿瘤细胞周期的S期阻滞,同时提高组蛋白H3和α-微管蛋白的乙酰化水平并持续抑制胸苷酸合成酶(TS)表达。本文的核心研究对象 Vorinostat (SAHA, MK0683,AbMole,M1780) 由AbMole提供。2014年,AbMole的两款抑制剂分别被西班牙国家心血管研究中心和美国哥伦比亚大学用于动物体内实验,相关科研成果发表于顶刊 Nature 和 Nature Medicine。
