Description

一种嘧啶并嘧啶类衍生物及其制备方法和在医药上的应用
技术领域
本发明涉及化学药物领域,更涉及一种新的嘧啶并嘧啶衍生物、其制备方法及含有该衍生物的药物组合物以及其作为治疗剂特别是作为GPR119激动剂和在制备治疗抗糖尿病和代谢性病症等疾病的药物的用途。
背景技术
糖尿病是严重威胁人类健康的疾病,由于长期存在的高血糖,糖尿病会导致各种器官组织,特别是眼、肾、心脏、血管、神经的慢性损害和功能障碍。根据病因不同,糖尿病可分为1型糖尿病、2型糖尿病和妊娠期糖尿病等类型。其中,2型糖尿病占患病人口的90%,胰岛β细胞功能缺陷是导致2型糖尿病的主要原因。
现代药理学对2型糖尿病治疗方法主要集中在三个方面:a)改善胰岛素的增敏性,b)通过胰岛β细胞以葡萄糖依赖或非依赖方式促进胰岛素的释放, c)胰岛素的替代物。目前,临床上使用的抗2型糖尿病药物有胰岛素类、双胍类、噻唑烷二酮类、磺酰脲类、α-葡萄糖苷酶抑制剂、胰高血糖素样肽-1(glucagon-like peptide-1, GLP-1)类似物和二肽基肽酶-4(dipetidyl peptidase-4, DPP-4)抑制剂等类型。但这些药物都存在着一定的副作用,如:低血糖症、体重增加、β细胞功能下降、液体潴留和胃肠道副作用等。近年来出现的GPR119激动剂是用来治疗2型糖尿病的新靶点,由于其有效、安全的作用机制已被各大药企和研究院所用来开发抗2型糖尿病药物。
GPR119是一类A型视紫红质孤立的G蛋白偶联受体。人源性GPR119的基因定位于Xq26.1,该基因的开放阅读框架仅有一个外显子组成,不含内含子,其编码335个氨基酸。不同的脊椎动物物种也含有GPR119,包括小鼠、大鼠、猴和狗。GPR119在特定的肝脏、胃肠道的K细胞和L细胞及胰岛β细胞表达。在这三种细胞中,GPR119与激动剂结合后能够活化腺苷酸环化酶,提升cAMP的水平。这促进了GLP-1、葡萄糖依赖性促胰岛素释放多肽(glucose-dependent insulinotropic peptide, GIP)和胰岛素的释放。同时,GLP-1和GIP可与β细胞的受体结合,进一步诱导胰岛素的释放,因而GPR119激动剂通过两种直接的作用机制提升胰岛素的释放;GLP-1(或是GIP)也能够保持胰岛β细胞活力。因此口服GPR119激动剂不但可以促进胰岛素的分泌,而且可以保护β细胞活力,这就有效的改善了2型糖尿病人体内的葡萄糖平衡。
GPR119激动剂具有应用在治疗糖尿病和相关联症状上的价值,尤其是对于二型糖尿病,肥胖,葡萄糖耐受不良,胰岛素抵抗,代谢综合症,高血脂,血胆脂醇过多,以及动脉硬化症。
尽管目前已公开了一系列的治疗糖尿病和代谢性疾病等疾病的GPR119激动剂,但仍需要开发新的具有更好的药效的化合物,本发明设计具有通式Ⅰ所示的结构的化合物,并发现具有此类结构的化合物表现出优异的效果和作用。

GPR119激动活性
首先将含有人GPR119基因的DNA片段转染到HEK293细胞(人胚肾293细胞)中,通过培养得到稳定表达GPR119的细胞株,在96孔板上接种该细胞株。细胞在37℃,5%CO2条件下培养48 h后,移去培养液,加入100 μL缓冲液,并于室温孵育15 min。再给予不同浓度的待测化合物,孵育30 min后,移去缓冲液,加入75 μL预冷的裂解液,并在冰上孵育20 min,适当地振荡。将裂解液转移到1.5 mL离心管中,以13000 rpm的转速离心10 min。取50 μL上清液,采用HTRF cAMP试剂盒标准步骤,以OEA为阳性对照,测定细胞内cAMP的浓度,由剂量依赖的cAMP浓度变化获得化合物EC50值,用于评价化合物对受体的亲和力强弱,计算化合物刺激cAMP作用与OEA产生最大作用的比值(%max),用于比较化合物对受体的内在活性(IA)。
上表显示了本发明的化合物对hGPR119具有良好的激动活性。
