Description

二酰基乙二胺化合物
技术领域
本发明涉及可用作医药组合物(例如,用于治疗肥胖症的医药组合物)的有效成分的二酰基乙二胺化合物。
背景技术
肥胖症是这样一种状态:在生物体内,能量摄取与能量消耗的平衡破坏,剩余的能量以中性脂肪(主要是甘油三酸酯)的形式过剩地蓄积在脂肪组织中;肥胖症与耐胰岛素性、糖尿病、动脉硬化、非酒精性脂肪性肝炎、或高血压等疾病的发病、发展密切相关。另外,已知的是,除了在脂肪组织中之外,过剩的甘油三酸酯在肝脏、肌肉等中的蓄积也会引起这些组织中的功能障碍。近年来,随着生活习惯的改变,肥胖症患者有所增加,但是,针对这些肥胖症患者的治疗方法有限,人们期望开发新的肥胖治疗药物。
DGAT是与甘油三酸酯生物合成途径的最终阶段(即,由二酰基甘油和脂肪酸酰基CoA生成甘油三酸酯的反应)有关的酶,据报告,DGAT有DGAT1、DGAT2亚型。已知DGAT1与DGAT2的氨基酸序列的同源性低,而与ACAT的同源性高(Proc.Nat.Acad.Sci.95:13018-13023,1998;J.Biol.Chem.276:38870-38876,2001)。作为DGAT1敲除小鼠的表现形式,据报道有对由高脂肪食物诱发的肥胖的耐性、耐胰岛素性改善、瘦素(leptin)感受性亢进、肝脏中脂肪量降低、能量消耗亢进等(Nature Genetics 25:87-90,2000;J.Clin.Invest.109:1049-1055,2002)。另外,由于DGAT1杂合子敲除小鼠显示出介于野生型小鼠和纯合子缺失小鼠之间的表现形式(Arterioscler.Thromb.Vasc.Biol.25;482-486,2005),因此据认为,DGAT1抑制可有望作为肥胖、II型糖尿病、脂肪肝、以及由它们引起的相关疾病的药物治疗的目标。
例如,据报道,下式所示化合物具有DGAT1抑制作用(专利文献1)。

[式中的符号参见该公报]
另外,据报道,下式所示化合物具有DGAT1抑制作用(专利文献2)。

另外,据报道,下式所示化合物具有DGAT1抑制作用(专利文献3)。

[式中的符号参见该公报]
进一步,除了上述之外,有人还报道了具有DGAT1抑制作用的化合物(专利文献4、专利文献5、专利文献6、专利文献7)。
另外,也有几个关于二酰基乙二胺化合物的报道(专利文献8、非专利文献1)。
但是,上述文献中均没有公开或暗示本发明涉及的式(I)所示化合物或其盐。

不添加被测试物质时的计数作为对照(添加DMSO时的TG)。不添加被测试物质及微粒体时的计数作为空白TG。根据下述计算式来求出被测试物质的DGAT1抑制率。
抑制率(%)=(添加被测试物质时的TG-空白TG)÷(添加DMSO时的TG-空白TG)×100
求出被测试物质在反应液中的浓度为1、10、100、1000nM时的DGAT1抑制率。将得到的抑制率进行线性回归,利用SAS 8.2software package(SAS Institute Japan,Ltd.,Tokyo,Japan)求出使DGAT1活性被抑制50%时所需要的被测试物质浓度(IC50)。
