Abstract
本发明涉及作为DPP‑4抑制剂的苯并六元环衍生物及其应用。具体而言,本发明涉及Ⅰ所示化合物、含有Ⅰ式化合物的药物组合物及所述化合物在制备治疗DPP‑4相关疾病或抑制DPP‑4的药物中的用途：
Description
技术领域
本发明涉及药物化学领域；具体地说，本发明涉及新型的苯并六元环衍生物，其合成方法及其作为DPP-4抑制剂在制备糖尿病相关疾病的药物中的应用。
背景技术
1.糖尿病是一代谢性疾病，体内胰岛素的缺乏或是机体对胰岛素利用率下降导致血糖水平升高是这一疾病的主要特征。如果不加以治疗，糖尿病会对机体造成严重损害，例如心血管疾病、肾病、神经疾病、视网膜病变失明等。据2019年国际糖尿病联盟会(IDF)报道显示，2019年全球约4.63亿成人患糖尿病，预计到2045年，糖尿病患者可能达到7亿。仅中国，2019年统计就约有1.164亿糖尿病患者(20-79岁)，大概占全球的1/4。糖尿病治疗周期较长，费用投入大，对家庭、国家经济及医疗体系都是沉重的负担。
2.糖尿病由其发病机制主要分为两类。第一类为Ⅰ型糖尿病，占5％-10％，主要是因为自身免疫性反应或遗传引起。第二类为Ⅱ型糖尿病，占90％左右,其病理机制主要是由胰岛素抵抗或分泌障碍导致的胰岛素缺乏，使得血糖，血脂的代谢出现异常。这也是糖尿病极易并发心脑血管、肾、眼底等微血管病变的原因。
3.对糖尿病的治疗临床上主要采用多种口服降糖药和胰岛素补充来延缓糖尿病进程。然而，这些方法有时无法达到预期治疗效果，且存在诱发低血糖、心血管疾病等副作用，对损伤的胰岛细胞也没有保护作用。随着对糖尿病的发病机制的深入了解，依据发病关键靶点作用机制寻找有效的降糖药物成为研究热点。
4.二肽基肽酶-Ⅳ(DPP-4)是已经证明治疗Ⅱ型糖尿病的有效靶点,它能迅速降解肠胰岛素血糖素样肽-1(GLP-1)和葡萄糖依赖性胰岛素释放肽(GIP)等多种重要的肠促胰岛素，从而导致胰岛素分泌不足。因此，DPP-4抑制剂可以提GLP-1和GIP水平，促进胰岛素分泌，降低血糖。
5.临床试验表明，DPP-4抑制剂可以降低血糖水平，增加葡萄糖耐量,且没有出现体重增加和低血糖等副作用。目前，已应用于临床的DPP-4抑制剂有西格列汀、沙格列汀、维格列汀、阿格列汀和利格列汀等。DPP-4抑制剂已经是降糖药物市场的主导。
6.然而,目前所有上市的DPP-4抑制剂都处于专利保护期内，还有多种新型DPP-4抑制剂处于临床前研究阶段。
因此，本领域急需研发新型、高效、低毒性的DPP-4抑制剂。
发明内容

实施例2.生物活性测试
1.DPP-4为应用杆状病毒表达系统Bac-to-Bac表达并纯化获得的蛋白酶DPP-4胞外片段(aa29-766)，DPP-4可特异性水解底物Ala-Pro-AMC生成产物AMC，AMC经过355nm的紫外光激发产生460nm的发射光，动态测量单位时间内460nm波长处荧光值线性变化可显示为DPP-4的二肽基肽酶活性。
2.将受试化合物、酶和反应缓冲液混匀，温室孵育30min后，加入底物启动反应，5分钟内连续测定460nm波长处荧光值变化。同时设以DMSO替代受试化合物的溶剂对照组、以及奥格列汀阳性对照组。反应终体积为50μl,具体反应体系为：2％DMSO，0.1nM DPP-4，10μMAla-Pro-AMC，100mM Hepes pH 7.5，0.1mg/ml牛血清白蛋白(BSA)。每个样品每个浓度设2个复孔。其数据首先计算酶初速度期内单位时间荧光强度的增量(单位：RFU/sec)，以此代表酶的初速度，然后计算样品各浓度组的活性百分数(％Activity)，公式如下：
其中VSample表示样品各浓度组的初速度，VDMSO表示DMSO组的初速度。以浓度的对数值对活性百分数作图，然后采用非线性回归算出拟合曲线，利用软件GraphPad Prism 5公式log(inhibitor)vs.response-Variable slope计算得到IC50值
3.化合物对DPP-4抑制IC50值：
ND：未检测
讨论：
发明人经过广泛而深入的研究，设计并合成得到了一系列未见文献报道的苯并六元环衍生物，对得到的化合物进行了分子水平活性测试，得到一批能够抑制DPP-4的化合物。为由DPP-4介导的疾病的治疗奠定了基础。
