strategy for the treatment of cancer and HDAC6 inhibitors were considered to be potent anti-cancer agents. In this work, celecoxib showed moderate degree of HDAC6 inhibition activity and selectivity in preliminary enzyme inhibition activity assay. A series of hydroxamic acid derivatives bearing phenylpyrazol moiety were designed and synthesized as HDAC6 inhibitors. Most compounds showed potent HDAC6 inhibition
近年来,抑制HDAC6成为治疗癌症的有前途的治疗策略,并且HDAC6抑制剂被认为是有效的抗癌药。在这项工作中,塞来昔布在初步的酶抑制活性测定中显示出中等程度的HDAC6抑制活性和选择性。设计并合成了一系列带有苯并吡唑部分的异羟肟酸衍生物,作为HDAC6抑制剂。大多数化合物显示出有效的HDAC6抑制活性。11i是针对HDAC6的最具选择性的化合物,IC 50值为0.020 µM,选择性系数为101.1。结构-活性关系分析表明,在吡唑的1'端定位连接基团具有最大的选择性。最多的化合物11i(GI 50 = 3.63μM)在HepG2细胞中表现出的效力比伏立诺他高6倍。考虑到对HDAC6的高选择性和抗增殖活性,这类化合物具有开发成为抗癌剂的潜力。
