  • Diabetes mellitus is a chronic comprehensive disease mainly caused by glucose metabolism disorder caused by absolute or relative shortage of insulin or decreased sensitivity of target cells to insulin. It is divided into type I diabetes mellitus and type II diabetes mellitus. Among them, type II diabetes is adult-onset diabetes mellitus, an endocrine disease mainly manifested by chronic hyperglycemia caused by insulin resistance and/or insulin secretion defect. Type II diabetes patients account for more than 90% of diabetic patients. According to the Global Diabetes Map, there were approximately 425 million diabetic patients in the world in 2017, of which China ranked first in the world with approximately 114.4 million diabetic patients. It is estimated that by 2045, there will be 629 million people with diabetes worldwide. It can be seen that diabetes is a very common chronic disease all over the world.

  • GLP-1 receptor agonists are one of the most effective diabetes treatment drugs, and insulin preparations are still the global The most used diabetes drug, about 30-40% of type 2 diabetes patients eventually need to use insulin.
  • GLP-1 preparations mainly include exenatide, liraglutide, semaglutide, etc., suitable for metformin, sulfonic acid Patients with type 2 diabetes who cannot adequately control blood sugar when combined with ureides.
  • insulin preparations and GLP-1 preparations are basically polypeptide drugs and injection preparations. Even oral semaglutide still has many limitations in drug use. Therefore, it is still necessary to further develop small molecules of GLP-1 receptors. Agonist drugs.
  • GLP-1 stimulates insulin secretion in a glucose-dependent manner, and inhibits glucagon secretion in a glucose-dependent manner, so there is no risk of hypoglycemia.
  • GLP-1 can increase the amount of insulin produced by beta cells and improve the responsiveness of beta cells to glucose.
  • GLP-1 can delay gastric emptying, reduce food intake, and thus have the effect of weight loss.
  • GLP-1 also has the unique effect of cardiovascular and cerebrovascular benefits.

Description

噻吩类GLP-1受体激动剂及其用途 技术领域
本发明涉及医药技术领域，具体涉及GLP-1受体激动剂化合物及制备方法，以及所述化合物在用于制备治疗或预防GLP-1介导的疾病及相关疾病的药物中的用途。
背景技术
糖尿病是一种因胰岛素绝对或相对不足，或者靶细胞对胰岛素敏感性降低引起的以糖代谢紊乱为主的慢性综合性疾病，分为I型糖尿病和II型糖尿病。其中，II型糖尿病是成人发病型糖尿病，由于胰岛素抵抗和/或胰岛素分泌缺陷引起的以慢性血糖升高为主要表现的内分泌疾病。II型糖尿病患者占糖尿病患者90％以上。根据全球糖尿病地图显示，2017年全球约有4.25亿糖尿病患者，其中中国糖尿病患者位居世界第一，数量约为1.144亿。预计到2045年，全球将有6.29亿糖尿病患者。可见，糖尿病是全球都十分普遍的慢性病。
目前可用于治疗II型糖尿病的主要有以下几类药物：促胰岛素分泌剂，二甲双胍类，α-糖苷酶抑制剂，胰岛素增敏剂，钠-葡萄糖协同转运蛋白2抑制剂，二肽基肽酶-4(DPP-4)抑制剂，GLP-1受体激动剂，胰岛素及其类似药物等，其中胰岛素及GLP-1受体激动剂是最有效的糖尿病治疗药物之一，胰岛素制剂仍然是全球使用量最多的糖尿病用药，约有30-40％的2型糖尿病患者最终需要使用胰岛素，GLP-1制剂主要有艾塞那肽，利拉鲁肽，索马鲁肽等，适用于二甲双胍、磺酰脲类等联合应用不能充分控制血糖的2型糖尿病人。但是目前胰岛素制剂和GLP-1制剂基本上都是多肽类药物及注射制剂，即便是口服索玛鲁肽，在用药上仍有诸多限制，因此仍有必要进一步开发GLP-1受体的小分子激动剂药物。
GLP-1以葡萄糖依赖的方式刺激胰岛素分泌，并且以葡萄糖依赖的方式抑制胰高糖素分泌，因而没有低血糖风险。GLP-1能够增加β细胞产生胰岛素的量，提高β细胞对葡萄糖的反应性。GLP-1可以延缓胃排空，减少食物摄入，因而具有减轻体重的功效。此外，GLP-1还具有心脑血管获益的独特效果。GLP-1受体激动剂在临床应用中被定位于介于口服降糖药和胰岛素之间的过渡阶段使用，并且可与其它药物联用，成为过去五年增长最快，也是未来最具成长潜力的降糖药物。
和II型糖尿病相关的其他病症包括糖尿病肾病、糖尿病眼部并发症(糖尿病性视网膜病变、与糖尿病相关的葡萄膜炎、糖尿病性白内障)、糖尿病足、糖尿病心血管并发症、糖尿病性脑血管病、糖尿病神经病变、肥胖症、高血压。
GLP-1受体激动剂作为一款极具潜力的药物，目前市面多数是注射给药的形式。开发口服小分子GLP-1受体激动剂，可以改善患者依从性，是未来GLP-1受体激动剂的发展趋势。目前已知的GLP-1受体激动剂小分子研发进展如下：
文献WO2009111700A2公开了一系列氧杂二氮杂蒽类GLP-1受体激动剂化合物；WO2010114824A1公开了一系列取代的偶氮蒽衍生物的GLP-1受体激动剂化合物；WO2017078352A1公开了一系列环己烯衍生物的GLP-1受体激动剂化合物；KR1020180101671A公开了一系列杂芳基取代的吡啶[1,2-a]并咪唑类衍生物的GLP-1受体激动剂化合物；WO2018056453A1公开了一系列吡唑并吡啶衍生物的GLP-1受体激动剂化合物；以及WO2018109607A1公开了一系列与本申请相似的GLP-1受体激动剂化合物等。

本发明提供的化合物及其药学上可接受的盐可以是以手性形态存在的，即S构型或R构型。本发明提供的化合物及其药学上可接受的盐可以是以非手性形态存在的。本发明所表述的化合物，当以其中一种构型例举结构时，也表示公开了其另一种构型或非手性形式的结构。
本发明所述的化合物包括化合物的立体异构体。本发明所述的立体异构体是指当如式I所示的化合物存在不对称碳原子时，会产生对映异构体；当化合物存在碳碳双键或环状结构时，会产生顺反异构体；当化合物存在酮或肟时，会产生互变异构体。作为一种具体的实施方案，本发明所述的立体异构体包括但不限于：对映异构体、非对映异构体、消旋异构体、顺反异构体、互变异构体、几何异构体、差向异构体及其混合物。
本发明的化合物可以存在特定的几何或立体异构体形式。本发明设想所有的这类化合物，包括 顺式和反式异构体、(-)-和(+)-对映体、(R)-和(S)-对映体、非对映异构体、(D)-异构体、(L)-异构体，及其外消旋混合物和其他混合物，例如对映异构体或非对映体富集的混合物，所有这些混合物都属于本发明的范围之内。烷基等取代基中可存在另外的不对称碳原子。所有这些异构体以及它们的混合物，均包括在本发明的范围之内。
除非另有说明，术语“对映异构体”或者“旋光异构体”是指互为镜像关系的立体异构体。
除非另有说明，术语“顺反异构体”或者“几何异构体”系由因双键或者成环碳原子单键不能自由旋转而引起。

除非另有说明，“(+)”表示右旋，“(-)”表示左旋，“(±)”表示外消旋。

可以通过手性合成或手性试剂或者其他常规技术制备光学活性的(R)-和(S)-异构体以及D和L异构体。如果想得到本发明某化合物的一种对映体，可以通过不对称合成或者具有手性助剂的衍生作用来制备，其中将所得非对映体混合物分离，并且辅助基团裂开以提供纯的所需对映异构体。或者，当分子中含有碱性官能团(如胺基)或酸性官能团(如羧基)时，与适当的光学活性的酸或碱形成非对映异构体的盐，然后通过本领域所公知的常规方法进行非对映异构体拆分，然后回收得到纯的对映体。此外，对映异构体和非对映异构体的分离通常是通过使用色谱法完成的，所述色谱法采用手性固定相，并任选地与化学衍生法相结合(例如由胺生成胺基甲酸盐)。
本发明的化合物可以在一个或多个构成该化合物的原子上包含非天然比例的原子同位素。例如，可用放射性同位素标记化合物，比如氚( 3H)，碘-125( 125I)或C-14( 14C)。又例如，可用重氢取代氢形成氘代药物，氘与碳构成的键比普通氢与碳构成的键更坚固，相比于未氘化药物，氘代药物有降低毒副作用、增加药物稳定性、增强疗效、延长药物生物半衰期等优势。本发明的化合物的所有同位素组成的变换，无论放射性与否，都包括在本发明的范围之内。
本发明的术语“药学上可接受的”是指针对那些化合物、材料、组合物和/或剂型而言，它们在可靠的医学判断的范围之内，适用于与人类和动物的组织接触使用，而没有过多的毒性、刺激性、过敏性反应或其它问题或并发症，与合理的利益/风险比相称。
本发明的术语“药学上可接受的盐”是指本发明化合物的盐，由本发明发现的具有特定取代基的化合物与相对无毒的酸或碱制备。当本发明的化合物中含有相对酸性的官能团时，可以通过在纯的溶液或合适的惰性溶剂中用足够量的碱与这类化合物接触的方式获得碱加成盐。药学上可接受的碱加成盐包括钠、钾、钙、铵、有机胺或镁盐或类似的盐。当本发明的化合物中含有相对碱性的官能团时，可以通过在纯的溶液或合适的惰性溶剂中用足够量的酸与这类化合物接触的方式获得酸加成盐。药学上可接受的酸加成盐的实例包括无机酸盐，所述无机酸包括例如盐酸、氢溴酸、硝酸、碳酸、碳酸氢根、磷酸、磷酸一氢根、磷酸二氢根、硫酸、硫酸氢根、氢碘酸、亚磷酸等；以及有机酸盐，所述有机酸包括如乙酸、丙酸、异丁酸、马来酸、丙二酸、苯甲酸、琥珀酸、辛二酸、反丁烯二酸、乳酸、扁桃酸、邻苯二甲酸、苯磺酸、对甲苯磺酸、柠檬酸、酒石酸和甲磺酸等类似的酸；还包括氨基酸(如精氨酸等)的盐，以及如葡糖醛酸等有机酸的盐。本发明的某些特定的化合物含有碱性和酸性的官能团，从而可以被转换成任一碱或酸加成盐。
本发明的药学上可接受的盐可由含有酸根或碱基的母体化合物通过常规化学方法合成。一般情况下，这样的盐的制备方法是：在水或有机溶剂或两者的混合物中，经由游离酸或碱形式的这些化合物与化学计量的适当的碱或酸反应来制备。
本发明的术语“任选”或“任选地”指的是随后描述的事件或状况可能但不是必需出现的，并且该 描述包括其中所述事件或状况发生的情况以及所述事件或状况不发生的情况。
本发明的术语“被取代的”是指特定原子上的任意一个或多个氢原子被取代基取代，可以包括重氢和氢的变体，只要特定原子的价态是正常的并且取代后的化合物是稳定的。当取代基为氧(即＝O)时，意味着两个氢原子被取代。氧取代不会发生在芳香基上。术语“任选被取代的”是指可以被取代，也可以不被取代。除非另有规定，取代基的种类和数目在化学上可以实现的基础上可以是任意的。
本发明的术语“任选地被取代”意指“被取代”和“未被取代”两种情形。
当任何变量(例如R)在化合物的组成或结构中出现一次以上时，其在每一种情况下的定义都是独立的。因此，例如，如果一个基团被0-2个R所取代，则所述基团可以任选地至多被两个R所取代，并且每种情况下的R都有独立的选项。此外，取代基和/或其变体的组合只有在这样的组合会产生稳定的化合物的情况下才是被允许的。
当一个连接基团的数量为0时，比如-(CRR) 0-，表示该连接基团为单键。
当一个取代基数量为0时，表示该取代基是不存在的，比如-A-(R) 0表示该结构实际上是-A。
当一个取代基为空缺时，表示该取代基是不存在的，比如A-X中X为空缺时表示该结构实际上是A。
当其中一个变量选自单键时，表示其连接的两个基团直接相连，比如A-L-Z中L代表单键时表示该结构实际上是A-Z。
当一个取代基的键可以交叉连接到一个环上的两个或两个以上原子时，这种取代基可以与这个环上的任意原子相键合，例如，结构单元
Figure PCTCN2022081466-appb-000044

当所列举的连接基团没有指明其连接方向，其连接方向是任意的，例如，
Figure PCTCN2022081466-appb-000045
中连接基团L为-M-W-，此时-M-W-既可以按与从左往右的读取顺序相同的方向连接环A和环B构成

也可以按照与从左往右的读取顺序相反的方向连接环A和环B构成
Figure PCTCN2022081466-appb-000047
所述连接基团、取代基和/或其变体的组合只有在这样的组合会产生稳定的化合物的情况下才是被允许的。
除非另有规定，当某一基团具有一个或多个可连接位点时，该基团的任意一个或多个位点可以通过化学键与其他基团相连。当该化学键的连接方式是不定位的，且可连接位点存在H原子时，则连接化学键时，该位点的H原子的个数会随所连接化学键的个数而对应减少变成相应价数的基团。所述位点与其他基团连接的化学键可以用直形实线键

4.给药制剂的制备
溶媒对照配制：在细胞外液中加入一定体积的DMSO，使其与最终供试品溶液含有同等含量的DMSO(若供试品溶液含有不同DMSO含量，以最大DMSO含量为准)，用以排除DMSO对细胞自身电流的干扰。
供试品配制：将上述10mM储液母液按比例配制成所需浓度的DMSO储备液(一般为实际给药浓度的1000/3倍)，最后将储备液用细胞外液稀释成实验所需的给药浓度。
阳性对照溶液配制：称取适量阳性对照品置于合适容器中，加入一定体积的DMSO，充分搅拌或振荡使全部溶解，配制成10mM的储备溶液，接着按比例配制成所需浓度的储备液，最后将储备液用细胞外液稀释成实验所需的给药浓度。
工作浓度溶液使用前应检查有无沉淀析出，如果有沉淀析出，将稀释储备液，提高细胞外液中DMSO终浓度，但细胞外液中DMSO最终浓度不超过0.5％。实验中采用从低浓度到高浓度连续灌流的方式。实验结束后，剩余供试品和阳性对照品的给药溶液以废液处理。

电生理实验：
采用全细胞膜片钳技术记录hERG电流。取细胞悬液加于小培养皿中，置于倒置显微镜载物台上。待细胞贴壁后，用细胞外液灌流，推荐流速为1–2mL/min。玻璃微电极由微电极拉制仪两步拉制，充灌电极内液后其入水电阻值为2-5MΩ。
建立全细胞记录模式后，保持钳制电位为-80mV。给予去极化电压至+60mV持续850ms，然后复极化至-50mV维持1275ms引出hERG尾电流。这样一组脉冲程序每15秒钟重复一次，贯穿整个实验。
电流稳定后采用从低浓度到高浓度胞外连续灌流给药的方式。从低浓度开始，持续灌流至药效稳定，然后进行下一浓度的灌流。本实验将分别测试各供试品和阳性对照对hERG尾电流的阻断效应(N≥2)；具体实际浓度可根据实际溶解度和效应进行调节，不视为方案偏离。
药效稳定的定义为：每个浓度给药阶段的最后5个刺激条电流值变化小于均值的10％(当电流大于等于200pA时)或小于均值的30％(当电流小于200pA时)可认为是稳定的，若不稳定，将不采取该浓度数据。
6.数据分析
在数据处理中，判断对hERG的阻断效应时，将尾电流的峰值和其基线进行校正。用尾流的抑制率(inhibition rate，IR)表示不同浓度下各化合物的作用。所有细胞各个浓度的％IR的SD≤15，作为可接受标准(除异常数据外)。
IR＝100％×(给药前尾电流峰值-给药后尾电流峰值)/给药前尾电流峰值。
