(NO) on histone deacetylases (HDACs), a series of N-acyl-o-phenylenediamine-based HDAC inhibitors equipped with the phenylsulfonylfuroxan module as NO donor was designed, synthesized and biologically evaluated. The in vitro HDAC inhibitory assays revealed that compared with the clinical class I selective HDAC inhibitor MS275, compounds 7c, 7d and 7e possessed similar HDAC inhibitory potency and selective
基于多种机制的抗肿瘤策略和一氧化氮(NO)对组蛋白脱乙酰基酶(HDACs)的调节作用,设计了一系列以N-酰基-邻苯二胺为基础的HDAC抑制剂,其以苯磺酰基呋喃喃模块为NO供体,合成和生物学评估。体外HDAC抑制试验表明,与临床I类选择性HDAC抑制剂MS275相比,化合物7c,7d和7e具有相似的HDAC抑制能力和选择性特征,这已通过蛋白质印迹分析的结果得到证实。免疫印迹分析还显示,NO清道夫N-乙酰基半胱氨酸(NAC)可能削弱化合物的胞内HDAC抑制能力7c中,支持由所产生NO的HDAC抑制作用7C。值得注意的是,化合物7c,7d和7e对所有四种测试的实体瘤细胞系均表现出比MS275更有效的体外抗增殖活性。在HCT116异种移植模型中证明了有希望的7c体内抗肿瘤效力。
