组蛋白去乙酰化酶(HDAC)是调节乙酰化组蛋白浓度的酶,乙酰化组蛋白与BET(Bromodomain and Extracellular domain)蛋白的溴域(BRD)相互作用,影响转录活性。同时阻断这两个表观遗传学因子已在各种癌细胞系中显示出协同作用。本文报道了我们设计、合成和活性测试的新型双重抑制剂,通过向一些先前由我们开发的含苯二氮平核心的HDAC抑制剂添加甲基三唑基团而获得。Alphascreen FRET试验表明,这些化合物能够与BRD4-1和BRD4-2蛋白相互作用,对后者具有一定的选择性,而HDAC抑制性质则通过免疫沉淀试验测量。抗增殖活性在C26腺癌、SSMC2黑色素瘤和SHSY5Y神经母细胞瘤细胞上进行了测试。有趣的是,这两种化合物在小鼠剩余神经损伤(SNI)模型中具有抗高痛感作用。
Histone deacetylases (HDAC) are enzymes that regulate the concentration of acetylated histones which, in turns, interact with the bromodomain (BRD) of BET (Bromodomain and Extracellular domain) proteins to affect transcriptional activity. Simultaneous blockade of both epigenetic players has shown synergistic effects in a variety of cancer cell lines. In this paper we report the design, synthesis and activity of new dual inhibitors, obtained by adding a methyltriazole moiety to some HDAC inhibitors carrying a benzodiazepine core, which were previously developed by us. An Alphascreen FRET assay showed that the compounds were able to interact with BRD4-1 and BRD4-2 proteins, with some selectivity for the latter, while the HDAC inhibiting properties were measured by means of an immunoprecipitation assay. The antiproliferative activity was tested on C26 adenocarcinoma, SSMC2 melanoma and SHSY5Y neuroblastoma cells. Interestingly, both compounds were endowed with antihyperalgesic activity in the mouse Spared Nerve Injury (SNI) model.
