Abstract

本发明涉及一种新型氨基‑苯基‑磺酰基‑乙酸酯衍生物或其药学上可接受的盐;以及一种包含其作为活性成分的用于预防或治疗糖尿病的药物组合物。

Description

新型氨基-苯基-磺酰基-乙酸酯衍生物及其用途
技术领域
本发明涉及新型氨基-苯基-磺酰基-乙酸酯衍生物或其药学上可接受的盐;以及包含其作为活性成分的用于预防或治疗糖尿病的药物组合物。
背景技术
2型胰岛素抵抗性糖尿病是典型的代谢性疾病,占总糖尿病病例的约90%。控制体内存在的血糖的主要物质是胰岛素,并且当胰岛素受体接受刺激时,胰岛素通过复杂的信号途径分泌。在2型糖尿病中,可能发生胰岛素抵抗,其中诸如肌肉、肝脏、胰腺等器官对胰岛素没有适当地反应。通常地,当血糖浓度升高时,胰岛素分泌也增加,以帮助血糖浓度恢复到正常水平,但在2型糖尿病患者中胰岛素没有正确分泌,因此维持高血糖水平,其可直接导致糖尿病。
目前用于治疗2型糖尿病的治疗剂包括胰岛素、二甲双胍(抑制肝脏葡萄糖产生的物质)、磺酰脲类(刺激胰腺中β细胞胰岛素分泌的物质)、α-葡萄糖苷酶抑制剂(抑制葡萄糖吸收的物质)和噻唑烷衍生物(增强胰岛素敏感性的物质)等,并且最近,使用艾塞那肽(GLP-1类似物)、DPP IV抑制剂、SGLT-2抑制剂(抑制肾脏中的葡萄糖吸收)等。然而,已经报道了包括由胰岛素引起的低血糖、由二甲双胍引起的胃肠道副作用等、由噻唑烷衍生物引起的水肿等的不良副作用,此外,还报道了由GLP-1类似物和DPP IV抑制剂引起的胰腺炎以及SGLT-2引起的尿道感染。因此,已经积极进行研究以开发可有效降低血糖而不引起副作用的新型糖尿病治疗剂。
发明内容
[技术问题]
本发明人已经进行了广泛的努力以找到可以用作糖尿病治疗剂的新型化合物,并且作为结果,他们已经证实了一系列氨基-苯基-磺酰基-乙酸酯衍生物可以有效地用于预防或治疗2型糖尿病,从而完成本发明。
[技术方案]
本发明的一个目的是提供新型氨基-苯基-磺酰基-乙酸酯衍生物或其药学上可接受的盐。
本发明的另一目的是提供用于预防或治疗糖尿病的药物组合物,其包含所述化合物或其药学上可接受的盐作为活性成分。
[有益效果]
本发明的新型氨基-苯基-磺酰基-乙酸酯衍生物的化合物有效降低血糖,因此可用于治疗2型糖尿病。

实验例1:GPR40激动剂细胞测定
同时,作为一种类型的G-蛋白偶联受体(GPCR)的GPR40是从胰腺充分表达的游离脂肪酸(游离脂肪酸;FFA)受体,并且已经报道了作为GPR40配体的化合物在治疗糖尿病中有效(国际专利申请WO 2004/041266和美国专利US 7,960,369)
为了证实根据本发明的化合物对GPR40信号传导途径的调节活性,使用其中人GPR40在CHO细胞中过表达的细胞系如下所述进行测定。特别地,将细胞在烧瓶中培养,然后用0.25%胰蛋白酶处理,使得细胞可以从烧瓶表面分离。通过加入培养基停止胰蛋白酶反应,并且离心并收集细胞。将收集的细胞悬浮在培养基中,以6×104个细胞/100μL等分到96孔黑色板的每个孔中,并在培养箱中培养24小时。除去培养基后,根据Fluo-4NW钙测定试剂盒(F362056)的说明用100μL的Fluo-4NW染料处理细胞,并在细胞培养箱中反应2小时。
以10mM浓度制备包括对照组的所有化合物,并然后从最大浓度6mM开始,用DMSO进行3倍梯级稀释。将梯级稀释的化合物再次使用钙缓冲溶液在6000nM、2000nM、667nM、222nM、74nM、25nM和8nM的浓度下在96孔板中稀释6倍,并且准备好使用。
2小时反应结束后,向装有100μL Fluo-4NW染料的细胞中加入20μL的6倍稀释的化合物,并使用Synergy Neo(Bio-Teck)以4秒间隔测量荧光120秒。以1000nM、333nM、111nM、37nM、12nM、4nM和1nM的终浓度对每种化合物进行处理。通过在用测量期间获得的RFU值处理测试材料之前校正默认值来测量结果,并且通过取每个浓度的最大RFU值而获得剂量-响应曲线图,以及计算EC50值,其是指显示最大值的50%活性的浓度。
作为结果,本发明的化合物显示出优异的活性,EC50值为100nM或更小。
实验例2:ICR小鼠中的口服葡萄糖耐量试验(OGTT)
为了评价根据本发明的化合物的体内控制血糖的能力,使用ICR小鼠进行口服葡萄糖耐量试验。在试验前一天,将正常ICR小鼠分成每组四只,并且禁食至少16小时。在测试当天的早晨测量并记录每只小鼠的体重。该化合物在0.5%甲基纤维素中以5mg/mL的浓度制备,使得其可以以50mg/kg的剂量施用,然后进一步稀释至浓度为2mg/kg、0.5mg/kg和0.1mg/kg,并且以相同的体积施用,使得其可以以20mg/kg、5mg/kg和1mg/kg的剂量施用。将葡萄糖溶解在饮用水中并制备为200mg/mL的浓度,使得其可以以2g/kg的剂量施用。在施用化合物之前,从尾静脉抽取少量的小鼠血液,并使用血糖计ACCU-CHEK Active(Art.No.2248891001)测量血糖并记录。将作为载体的溶剂(0.5%MC)和上述制备的化合物使用探针以每1kg体重10mL的剂量施用于所有小鼠。进一步给予葡萄糖,在0.5小时、1小时和2小时后测定各小鼠的血糖值。
所得结果表示为根据各实验组的血糖的平均值和标准偏差以及测量时间,并且使用WinNonlin Professional(ver 5.3)程序从血糖随时间的变化量计算葡萄糖给药后2小时的葡萄糖AUC0-2小时值。基于计算出的个体AUC0-2小时值,通过学生的t检验分析(p<0.05)以分析每组来统计确认降低血糖的显著效果。代表性地,对实施例1的化合物测量的结果显示在图1中。
