技术领域
本发明涉及药物化学和化学治疗领域。具体而言，本发明涉及一类通式(Ι)所示的环肽类化合物、其制备方法、药物组合物及其在制备治疗与组蛋白去乙酰化酯酶相关的疾病，尤其是癌症、神经变性疾病、疟疾和糖尿病等疾病中的用途。
背景技术：
组蛋白去乙酰化酯酶(histone deacetylase,HDAC)是一类蛋白酶，对染色体的结构修饰和基因表达调控发挥着重要的作用。一般情况下，组蛋白的乙酰化有利于DNA与组蛋白八聚体的解离，核小体结构松弛，从而使各种转录因子和协同转录因子能与DNA结合位点特异性结合，激活基因的转录。在细胞核内，组蛋白乙酰化与组蛋白去乙酰化过程处于动态平衡，并由组蛋白乙酰化转移酶(histone acetyltransferase,HAT)和组蛋白去乙酰化酶(histone deacetylase,HDAC)共同调控。
在肿瘤的表观遗传学研究中，组蛋白的乙酰化修饰对肿瘤的发生发展起重要作用。正常细胞体一旦出现核内组蛋白乙酰化与去乙酰化的失衡，即会导致正常的细胞周期与细胞代谢行为的改变而诱发肿瘤。组蛋白去乙酰化酶催化组蛋白的去乙酰化，维系组蛋白乙酰化与去乙酰化的平衡状态，与癌相关基因转录表达、细胞增殖分化及细胞凋亡等诸多过程密切相关。在癌细胞中，HDAC的过度表达导致去乙酰化作用的增强，通过恢复组蛋白正电荷，从而增加DNA与组蛋白之间的引力，使松弛的核小体变得十分紧密，不利于特定基因的表达，包括一些肿瘤抑制基因。
随着生命科学的深入发展，对肿瘤的致病和发病机制的分子生物学研究为开发低毒高效针对特异性分子靶标的抗肿瘤药物提供了基础。组蛋白去乙酰化酶(histone deacetylases，HDACs)是维持染色体的基本组成单位核小体中组蛋白乙酰化平衡的关键酶类之一，其催化组蛋白的去乙酰化作用，与基因转录抑制密切相关，牵涉到促基因沉默的诸多过程，是抗肿瘤药物设计中的热门靶标。组蛋白去乙酰化酶抑制剂(histone deacetylase inhibitors，HDACi)则可通过提高染色质特定区域组蛋白乙酰化，从而调控细胞凋亡及分化相关蛋白的表达和稳定性，诱导细胞凋亡及分化，成为一类新的抗肿瘤药物。HDACi不仅对多种血液系统肿瘤和实体瘤具有良好的治疗作用，而且具有肿瘤细胞相对较高选择性和低毒的优点。

实施例83 HDAC生化活性的测定
1.测定原理：化合物生化活的性测定是根据其抑制HDAC酶的去乙酰化作用程度来确定的。本实验主要测定与肿瘤增殖及转移密切相关的HDAC1，HDAC2，HDAC3，HDAC8，HDAC11五种亚型HDAC酶的去乙酰化作用程度。用荧光标记的含有乙酰化的赖氨酸侧链的底物和HDAC酶作用之后，该荧光底物被去乙酰化。去乙酰化后的荧光标记底物被酶裂解后，释放出荧光物质，该荧光物质在360nm光的激发下产生460nm的发射光。
2.具体步骤：HDAC的底物用反应缓冲液稀释至200M(反应浓度为20M)，将HDAC酶稀释至适当浓度，加入不同浓度待测化合物，37℃反应30分钟，然后加入相同体积的2倍浓度底物发展液(developer)，室温孵育15分钟，最后用微孔板读板仪测定读数，激发光为360nm，发射光为460nm，数据用Prime 4软件处理，结果见表1。本发明实施例中SAHA为辛二酰苯胺异羟肟酸(Suberoylanilide hydroxamic acid)；no activity表示无活性。
