Definitions

  • the invention relates to a class of methyl-substituted benzobisoxazole compounds and their application in the preparation of medicines for treating related diseases. Specifically, it relates to a compound represented by formula (P) or a pharmaceutically acceptable salt thereof.
  • Glucagon-like peptide-1 (GLP-1) receptor belongs to the family of G-protein coupled glucagon receptors and is a peptide hormone secreted by intestinal L cells. Widely distributed in the pancreas, stomach and small intestine mucosa, heart, lung, and central nervous system, GLP-1 specifically binds to its receptor to activate the cyclic adenylate (cAMP) and mitogen-activated protein kinase (MAPK) pathways in the cell membrane. After cAMP is activated, it stimulates the synthesis and secretion of insulin and inhibits the secretion of glucagon together with glucose.
  • cAMP cyclic adenylate
  • MAPK mitogen-activated protein kinase
  • GLP-1 can produce a variety of physiological functions, such as: inhibiting pancreatic ⁇ -cell apoptosis, improving pancreatic ⁇ -cell function; inhibiting glucagon secretion; delaying the emptying of gastric contents, suppressing appetite and food intake, etc.

技术领域
本发明涉及一类甲基取代的苯并二噁唑类化合物,及其在制备治疗相关疾病的药物中的应用。具体涉及式(P)所示化合物或其药学上可接受的盐。
背景技术
IDF全球糖尿病概览第9版发布的最新数据显示,目前有4.63亿成人(20-79岁)患有糖尿病。每4名糖尿病患者中就有3人(3.52亿人)处于工作年龄(即20-64岁)。这一数字预计到2030年会增至4.78亿,到2045年会增至7亿。另外还有110万20岁以下的儿童和青少年患有I型糖尿病。2017年的中国II型糖尿病防治指南中提到2013年全国调查中II型糖尿病患病率为10.4%,男性高于女性(11.1%比9.6%),未诊断的糖尿病患者占总数的63%。
胰高血糖素样肽-1(Glucagon-like peptide-1,GLP-1)受体属于G-蛋白偶联胰高血糖素受体家族,是由肠道L细胞分泌的一种肽类激素,广泛分布于胰腺、胃和小肠黏膜以及心、肺、中枢神经***,GLP-1与其受体特异性结合后激活细胞膜内环腺苷酸(cAMP)和丝裂原激活蛋白激酶(MAPK)通路。cAMP激活后与葡萄糖协同刺激胰岛素合成和分泌,抑制胰高血糖素分泌。同时,激活蛋白激酶、磷脂酰肌醇3激酶(PI3K)、MAPK通道,可以减缓β细胞凋亡,促使胰岛β细胞分化并增殖。由此,GLP-1可以产生多种生理功能,如:抑制胰岛β细胞凋亡,改善胰岛β细胞功能;抑制胰高血糖素分泌;延缓胃内容物排空,抑制食欲及摄食等。从2005年艾塞那肽获批上市以来,GLP-1受体激动剂不良反应温和(主要为胃肠道症状(如恶心、呕吐等)),具有除降糖以外的心血管获益、肾脏获益、改善心衰、降低体重、改善肝纤维化/肝功能指标等临床获益,逐渐成为国内外糖尿病指南优先推荐用药。但目前上市的GLP-1受体激动剂均为多肽类大分子药物,需要注射给药,患者依从性较差。多肽大分子药物的自身技术条件,也导致药物价格昂贵,存储要求高。
开发具有口服活性的小分子GLP-1受体激动剂,能方便患者使用,减轻医疗负担,提高依从性。小分子GLP-1受体激动剂有望成为更安全、优效的新型降糖药物满足糖尿病的治疗需求。
