8-Tetrahydro[1]benzothieno[2,3-d]pyrimidin-4(3H)-one derivatives bearing a hydroxamic acid, 2-aminoanilide and hydrazide moieties as zinc-binding group (ZBG) were designed, synthesized and evaluated for the HDAC inhibition activity and antiproliferative activity. Most of the tested compounds displayed strong to moderate HDAC inhibitory activity. Some of these compounds showed potent anti-proliferative activity against
一系列新颖的5,6,7,8-四氢[1]苯并噻吩并[2,3 - d ]嘧啶-4(3 H)-一衍生物,带有异羟肟酸,2-氨基苯胺和酰肼基团作为锌结合基团设计,合成(ZBG)并评估其HDAC抑制活性和抗增殖活性。大多数测试化合物显示出强到中等的HDAC抑制活性。这些化合物中的一些对人的HepG2,MCF-7和HCT-116细胞系显示出有效的抗增殖活性。特别地,与作为参考的SAHA相比,化合物IVa,IVb,IXa和IXb对测试的三种细胞系表现出显着的抗增殖活性。化合物IVb是SADAC的HDAC1和HDAC2的等价抑制剂。明显的是,游离的异羟肟酸基团的存在对于具有最大活性的与脂族6个碳的连接基的Zn结合亲和力是必不可少的。对接研究结果表明,化合物IVb可以占据HDAC2结合位点,并具有通过抑制HDAC发挥抗肿瘤活性的潜力,值得进一步研究。
