Definitions

  • the present disclosure relates to GLP-1 receptor agonists, compositions and uses thereof, and the compounds can be used for treating or preventing GLP-1 receptor-mediated diseases or disorders and related diseases or disorders.
  • Diabetes mellitus is a chronic comprehensive disease mainly caused by the disorder of glucose metabolism caused by absolute or relative insulin deficiency or decreased sensitivity of target cells to insulin. It is divided into type I diabetes and type II diabetes.
  • Type II diabetes is an endocrine disease characterized by chronic blood sugar elevation caused by insulin resistance and/or insulin secretion defects. Type II diabetes patients account for more than 90% of diabetic patients.
  • insulin secretagogues drugs for the treatment of type II diabetes are the following: insulin secretagogues, metformin, ⁇ -glucosidase inhibitors, insulin sensitizers, sodium-glucose cotransporter 2 inhibitors, dipeptidyl peptidase -4 (DPP-4) inhibitors, GLP-1 receptor agonists, insulin and similar drugs, among which insulin and GLP-1 receptor agonists are one of the most effective diabetes treatment drugs.
  • Insulin preparations are still the most used diabetes drug in the world, and about 30-40% of type II diabetic patients eventually need to use insulin.
  • GLP-1 preparations mainly include exenatide, liraglutide, semaglutide, etc., which are suitable for type II diabetic patients whose blood sugar cannot be fully controlled by the combination of metformin and sulfonylurea.
  • the current insulin preparations and GLP-1 preparations are basically polypeptide drugs and injection preparations. Even if semaglutide is taken orally, there are still many restrictions on drug use. Therefore, it is still necessary to further develop small-molecule agonist drugs for the GLP-1 receptor.
  • 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 ⁇ cells and improve the responsiveness of ⁇ cells to glucose.
  • GLP-1 can delay gastric emptying, reduce food intake, and thus have the effect of reducing body weight.
  • GLP-1 also has a unique effect of cardiovascular and cerebrovascular benefits.
  • GLP-1 receptor agonists are used in the transitional stage between oral hypoglycemic agents and insulin in clinical application, and can be used in combination with other drugs.
  • diabetic nephropathy diabetic eye complications (diabetic retinopathy, diabetes-associated uveitis, diabetic cataract), diabetic foot, diabetic cardiovascular complications, diabetic cerebrovascular disease , diabetic neuropathy, obesity, hypertension.

  • diabetic foot diabetic cardiovascular complications
  • diabetic cerebrovascular disease diabetic neuropathy, obesity, hypertension.
  • GLP-1 receptor agonist As a drug with great potential, GLP-1 receptor agonist is currently available in the form of injection. Oral administration of small-molecule GLP-1 receptor agonists can improve patient compliance, which is the development trend of GLP-1 receptor agonists in the future.

Description

GLP-1受体激动剂及其组合物和用途 技术领域
本公开涉及GLP-1受体激动剂及其组合物和用途,所述化合物可以用于治疗或预防GLP-1受体介导的疾病或病症及相关疾病或病症。
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。II型糖尿病是由于胰岛素抵抗和/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。
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II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II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。
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。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。小分子GLP-1受体激动剂的研发可见于:WO2009111700A2、WO2010114824A1、WO2017078352A1、KR1020180101671A、WO2018056453A1以及WO2018109607A1。
仍然需要开发在GLP-1受体激动活性、肠道吸收、安全性和药代动力学等性质中的一个或多个方面具有改善的特性的小分子GLP-1受体激动剂。

定义
本公开中,化合物是依据化学结构式命名的。如果用于表示同一化合物的化合物名称与化学结构式不符,则以化学结构式为准。
本公开中,除有另外说明,则本文中使用的科学和技术名词具有本领域技术人员通常理解的含义,然而为了更好地理解本公开,下面提供了部分术语的定义。当本公开所提供的术语的定义和解释与本领域技术人员通常理解的含义不同时,以本公开所提供的术语的定义和解释为准。
本公开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。本公开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。本公开所述的化合物,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。
本公开所述的化合物包括化合物的立体异构体。本公开所述的立体异构体是指当式I或式II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。在一些实施方案中,本公开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。
本公开的化合物可以存在特定的几何或立体异构体形式。本公开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公开的范围之内。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,均包括在本公开的范围之内。
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,术语“非对映异构体”是指分子具有两个或多个手性中心,并且分子间为非镜像的关系的立体异构体。
除非另有说明,“(+)”表示右旋,“(-)”表示左旋,“(±)”表示外消旋。
除非另有说明,用楔形实线键

和楔形虚线键
Figure PCTCN2022100685-appb-000105

Figure PCTCN2022100685-appb-000109
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。如果想得到本公开的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)。
本公开的术语“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。
本公开的术语“药学上可接受的盐”是指本公开的化合物的盐,由本公开的具有特定取代基的化合物与相对无毒的酸或碱制备。当本公开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。当本公开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以及有机酸盐,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。本公开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。
本公开的药学上可接受的盐可由含有酸根或碱性基团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。
本公开的术语“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。
本公开的术语“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。当取代基为氧代(即=O)时,意味着两个氢原子被取代。氧代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。
本公开的术语“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 PCTCN2022100685-appb-000110
表示其取代基R可在环己基或者环己二烯上的任意一个位置发生取代。当所列举的取代基中没有指明其通过哪一个原子连接到被取代的基团上时,这种取代基可以通过其任何原子相键合,例如,吡啶基作为取代基可以通过吡啶环上任意一个碳原子连接到被取代的基团上。
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 PCTCN2022100685-appb-000111
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
Figure PCTCN2022100685-appb-000112
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 PCTCN2022100685-appb-000113
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。

阿米替林或特非那定 1
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。
