Description

精氨酸衍生物
技术领域
本发明涉及作为MC4受体配体的新型精氨酸衍生物。
背景技术
有报告说促黑激素(α、β、γ-MSH、ACTH)在脑内由其前体POMC的加工进行生物合成,并与各种生理机能相关(Nature,278,423,1979)。促黑激素通过与其特异性受体结合而表达生理机能,目前促黑激素受体(MC受体)被分类为MC1~MC5五个亚型。已确认这些受体中的MC4受体在脑内特异性地表达,并在脑内广泛分布(J.Biol.Chem.,268,15174,1993;Mol.Endocrinol.,8,1298,1994)。
最近,发现MC4受体与食欲和肥胖症有关。有报告表明在对MC4和MC3受体使用选择性肽性激动剂以及拮抗剂的动物实验中,对禁食小鼠和各种肥胖模型表现出强力的抑制食欲作用(Nature,385,165,1997)。
另外,在MC4受体KO小鼠中发现明显的体重增加、血中胰岛素量、葡萄糖量增加(Cell,88,131,1997),确认MC4受体对摄食行为以及肥胖具有抑制作用。
另外,发现MC4受体在脑内除了分布在与摄食行为密切相关的丘脑下部之外,在海马、扁桃体等边缘区以及作为血清素神经的起始核的缝线核等处也广泛分布(Mol.Endocrinol.,8,1298,1994)。另外,发现ACTH以及α-MSH在动物实验中对体温调节(Brain Res.,18,473,1987)、血压(Am.J.Physiol.,257,R681,1989)、神经内分泌系统(Life Sci.,25,1791,1979)、学习/记忆(Neurosci.Biobehav.Rev.,4,9,1980)以及觉醒(Neurosci.Biobehav.Rev.,4,9.1980)有作用,并且有报告表明可以引发焦虑症状、丘脑下部-下垂体-肾上腺系统的活化(Pharmacol.Biochem.Behav.,36,631,1990;Peptides,17,171,1996;ibid,11,647,1990;ibid,11,915,1990;Pharmacol.Biochem.Behav.,12,711,1980)。但是,ACTH以及α-MSH是亚型非特异性的激动剂,但促黑激素受体亚型与这些生理机能的关系还不明确。
关于MC4受体,报道了肽性激动剂和拮抗剂(Nature,385,165,1997)。但是,它们与MC3受体也具有亲和性,不能作为对MC4受体具有选择性的配体使用。另外,对MC4受体具有特异性的配体则完全没有相关报告。所以,MC受体中,对在脑内特异表达的、在脑内广泛分布的MC4受体的相关生理机能也还不明确。
本发明的目的是提供对MC4受体具有亲和性以及特异性的作为医药品有用的肽性配体。
发明内容
本发明者通过对精氨酸衍生物进行深入的研究,结果发现了作为与MC4受体具有亲和性的配体的精氨酸衍生物,从而完成了本发明。
以下说明本发明。

(3)将(2)得到的中间体(4)(0.42g)、中间体5(0.24g)以及1-羟基苯并三唑1水合物(0.16g)溶解在二甲基甲酰胺(15ml)中,在冰冷却条件下加入1-(3,3-二甲基氨基丙基)-3-乙基碳化二亚胺盐酸盐(0.16g),缓慢升温至室温,搅拌一夜。将反应溶液注入乙酸乙酯和水的混合溶剂中,分液后将有机层依次用5%硫酸氢钾水溶液、饱和碳酸氢钠水溶液和饱和氯化钠水溶液洗涤,用无水硫酸钠干燥后,滤除干燥剂,减压浓缩。残渣在乙酸乙酯中结晶化,得到中间体6(0.43g)。
(4)将(3)得到的中间体6(0.40g)溶解在二氯甲烷(5ml)中,加入三氟乙酸(5ml),在室温下搅拌2小时。将反应液减压浓缩,注入饱和碳酸氢钠水溶液,用氯仿萃取。将有机层用无水硫酸钠干燥后,滤除干燥剂,减压下浓缩。将残渣溶解在二氯甲烷(3ml)中,加入乙酸酐(48mg)以及吡啶(37mg)的二氯甲烷溶液(1ml),在室温下搅拌2小时。将反应溶液减压下浓缩,注入乙酸乙酯,依次用水、5%硫酸氢钾水溶液、饱和碳酸氢钠水溶液以及饱和氯化钠水溶液洗涤,用无水硫酸钠干燥后,滤除干燥剂后减压浓缩。将残渣在乙酸乙酯中结晶化,得到中间体7(0.28g)。

试验例[MC4受体结合实验]
MC4受体结合实验按照Pharmacology & Toxicology,79,161-165、1996中记载的方法进行。从Biolinks公司购入在HEK-293细胞中表达人MC4受体的人MC4受体表达细胞膜。将细胞膜在含有2mM乙二胺四乙酸、10mM氯化钙以及100μM苯基甲基磺酰氟的50mM三羟甲基氨基甲烷-盐酸缓冲液(pH7.4)中进行均化。均化物以48,000×g在4℃下离心分离20分钟。将离心分离得到的沉淀物用同样的缓冲液再次均化,将均化物在以48,000×g在4℃下离心分离20分钟。该操作重复2次。将沉淀物在含有2mM乙二胺四乙酸、10mM氯化钙、100μM苯基甲基磺酰氟以及0.1%牛血清白蛋白的50mM三羟甲基氨基甲烷-盐酸缓冲液(pH7.4)中混悬使蛋白质浓度为100μg/ml,作为粗膜标品用于结合实验。使粗膜标品(0.25ml、25μg蛋白质)与[125I]Nle4-D-Phe7-α-MSH(最终浓度为0.2nM)在25℃下反应120分钟。反应结束后,用受体结合实验用细胞收集器将反应液在GF/C玻璃纤维滤纸(在含有0.5%牛血清的20mM三羟甲基氨基甲烷-盐酸缓冲液(pH7.4)中浸泡过2小时)上抽滤。用γ计数器测定滤纸上的反射活性。以在1μM的Nle4-D-Phe7-α-MSH存在下的结合量作为非特异性结合,以1μM的Nle4-D-Phe7-α-MSH不存在下的结合作为总结合,从总结合中减去非特异性结合,得到的数值作为特异性结合。将被检药物溶于100%DMSO溶液中,与[125I]Nle4-D-Phe7-α-MSH同时添加至膜标品中。由10-9~10-5浓度的抑制曲线计算得出IC50值。
结果例如化合物224的IC50值为690nM。
式[1]表示的化合物或其医药上允许的盐,作为对MC4受体具有亲和性以及特异性的肽性配体有用,可以作为医药品使用。
