Description
技术领域
本发明涉及医药,特别是新颖的酰胺衍生物或其盐及含有该衍生物和制药学上允许的载体的医药组合物。
背景技术
糖尿病是伴有持续高血糖状态的疾病,大多数是环境因素和遗传因子共同作用的结果。血糖的主要调节因子是胰岛素,高血糖是因胰岛素缺乏或抑制其作用的各因素过剩而造成的。
糖尿病主要可分为胰岛素依赖性糖尿病(IDDM)和胰岛素非依赖性糖尿病(NIDDM)2种。日本糖尿病患者的95%以上为NIDDM,随着生活状况的变化,存在患者人数增加的问题。
对于较轻的糖尿病的治疗主要采用饮食疗法、运动疗法及改善肥胖的方法;如果病情较重,则采用口服糖尿病药物(例如,磺酰脲剂等胰岛素分泌促进剂、增强胰岛素感应性的胰岛素感应性增强剂等);如果病情严重,则服用胰岛素制剂。但是,上述胰岛素分泌作用和感应性增强作用都只是个别作用,如果发明出兼具上述两种作用的化合物就可获得具备新的功能、作用极强、血糖控制更佳的糖尿病治疗剂。虽然对具备这两种作用的化合物BRL35135[4-(2-((2-(3-氯苯基)-2-羟乙基)氨基)丙基)苯氧基)乙酸甲酯]有所报道(例如,Br.J.Clin.Pharmacol.,42,291-300,1996),但其效果并不明显,其作为医药品的开发也已终止。
另一方面,EP 611003号记载了由以下通式表示的苯基取代的磺酰胺衍生物,由于其在人体中对β3肾上腺素受体具有选择性的刺激作用,所以,据报道对肥胖症、高血糖症等有效。但是,对这些化合物的胰岛素分泌促进作用和胰岛素感应性增强作用没有任何揭示。
(式中符号参考上述公报)
发明的揭示
本发明者们等对兼具胰岛素分泌促进作用和胰岛素感应性增强作用的化合物进行认真研究后发现,新颖的酰胺衍生物同时具备良好的胰岛素分泌促进作用和胰岛素感应性增强作用,从而完成了本发明。
即,由于兼具胰岛素分泌促进作用和胰岛素感应性增强作用,所以,本发明涉及对糖尿病的治疗有效的以下通式(I)表示的酰胺衍生物或其盐,还涉及含有该酰胺衍生物或其盐及制药学上允许的载体的医药组合物,特别涉及作为糖尿病治疗剂的医药组合物。

制备方法2
本制备方法是使胺化合物(V)和环氧化合物(VI)反应,合成本发明化合物(I)的方法。反应时可使胺化合物(V)和环氧化合物(VI)直接进行偶合反应,也可在前述惰性溶剂中,在加热~加热回流条件下,较好是在30~150℃的温度下,加热1~24小时。另外,还可使环氧化合物(VI)和胺化合物(V)的盐,例如,三氟乙酸盐或盐酸盐进行合成反应。此时,还可在反应混合物中添加碳酸氢钠或二异丙基乙胺等碱。
此外,上述各种制备方法中,还可利用重结晶,粉碎,制备薄层色谱法、W.C.Still等在J.Org.Chem.43,2923(1978)上记载的硅胶柱闪速色谱法、中压液体色谱法及HPLC除去不希望有的副产品,对生成物进行精制。从通过HPLC获得的化合物可分离出相应的盐。
前述制备方法所用的原料化合物可通过本领域技术人员公知的方法容易地制得。原料化合物的具有代表性的制备方法如下。(式中,R″表示氢原子或芳烷基系的保护基(例如,-低级亚烷基-可取代的芳基),以下相同)
本制备方法是i)使化合物(V)和化合物(VI)反应,合成化合物(VIIIa),ii)R″为氢原子时,对其进行保护,然后,iii)使化合物(VIII)进行还原反应而合成化合物(II)的方法。
步骤i)可与制备方法2同样进行,它们的反应温度和所用溶剂等条件都相同。ii)的保护反应,可按照常用的氨基保护反应进行,较好是使用焦碳酸二叔丁酯等。iii)的还原反应可利用金属还原或催化还原方法等。
制法A 制法B(式中,Y表示卤原子,R″表示低级烷基、芳烷基系的保护基,以下相同)
化合物(III)中,取代的噻唑基甲基羧酸衍生物可按照以下方法制得。
制法A:使化合物(IX)和化合物(X)在前述惰性溶剂中,在室温~加热回流条件下进行反应,获得化合物(XIa)。然后,使化合物(XIa)进行水解反应,获得化合物(IIIa)。根据X及R1的取代基的种类,需要进行保护和脱保护反应,该方法应很容易被本领域的技术人员理解。
制法B:以公知的2-氨基噻唑基-4-基羧酸酯(XII)为原料,利用作为常规方法的N-烷基化或酰基化反应,经过化合物(XIb)可获得化合物(IIIb)。(式中,Z表示-CN或-CH2-NHR″,以下相同)
本制备方法是使化合物(XIV)和化合物(III)进行酰胺化反应,获得化合物(XV),然后,进行a)还原反应(Z=CN时)或b)脱保护(Z=-CH2-NHR″时)反应而获得化合物(Va)的方法。
使化合物(XIV)和化合物(III)进行酰胺化反应的方法与前述制备方法1的步骤1相同。此外,也可按照常规方法,用化合物(III)的反应性衍生物低级烷基酯或芳烷基酯代替化合物(III)来进行酰胺化反应。从化合物(XV)到化合物(Va)的反应可采用a)还原法,如常用的催化还原或用氯化钴及硼氢化钠等进行还原的方法。进行反应时,如果是R4a′和R4b′为一体的=O化合物时,可还原为R4a=H、R4b=OH的化合物。b)脱保护反应的方法,与前述制备方法1的步骤2相同。
以上制得的本发明化合物(I)可作为游离化合物、经过常用的成盐处理而形成的盐、水合物、乙醇等各种溶剂合物或多晶型物质被分离而精制。分离而精制可采用萃取、浓缩、蒸馏、结晶、重结晶、各种色谱法等常用化学方法进行。
按照常用方法,利用异构体间的物理化学差异,可对各种异构体进行分离。例如,消旋化合物可利用一般的消旋拆分法(例如,与具有一般光学活性的酸(酒石酸等)形成非对映异构体盐的旋光拆分法等)获得立体化学上纯粹的异构体。另外,非对映异构体的混合物还可按照常用方法,例如,分步结晶法或色谱法等进行分离。此外,利用适当的具有光学活性的原料可制得具有光学活性的化合物。
产业上利用的可能性
本发明的通式(I)表示的酰胺衍生物或其盐由于兼具胰岛素分泌促进作用和胰岛素感应性增强作用,所以,作为糖尿病的治疗剂很有用。
本发明的化合物如后述的耐糖能力试验和胰岛素拮抗性动物模型的血糖降低试验所确认的那样,兼具良好的胰岛素分泌促进作用和胰岛素感应性增强作用,是一种对糖尿病很有用的化合物。
本发明化合物的效果可通过以下试验确认。
1.kk小鼠(胰岛素拮抗性模型:肥胖、高血糖)的血糖降低试验[胰岛素感应性增强作用]
使用雄性kk小鼠(血糖值200mg/dl以上),喂食后测定其血糖值,然后,随机分组。使小鼠强制口服受试药物,1天1次共4天,比较最后给药后15~18小时后的血糖值和给药前的血糖值(n=6),求出血糖降低率(%)。用玻璃毛细管(用肝素进行过处理)从小鼠尾静脉采血,经过除蛋白处理后,用葡萄糖氧化酶法对上清液中的葡萄糖量(mg/dl)进行比色定量,即可求出血糖值。
其结果是,不论是经口给药还是皮下给药,在服用了本发明的化合物后血糖值都比服用受试药物前有明显降低,经口服用10mg/kg药物的血糖降低率是实施例1的化合物为47%(P<0.01)、实施例2-b的化合物为52%(P<0.01)、实施例2-c的化合物为50%(P<0.01)及实施例4的化合物为56%(P<0.01)。从这些结果可看出,本发明的化合物具有良好的胰岛素感应性增强作用。
2.正常大鼠的耐糖性能试验[胰岛素分泌促进作用]
使用7周龄的雄性SD系大鼠,使其禁食一昼夜后,随机分组,使其口服葡萄糖,进行耐糖量试验(oral glucose tolerance test,OGTT)(n=4)。受试化合物在服用葡萄糖(2g/kg,口服)前30分钟经口给药。在戊巴比妥(65mg/kg)麻醉下,用经过肝素处理的玻璃毛细管从腹部大静脉采血,经过除蛋白处理后,利用葡萄糖氧化酶法对上清液中的葡萄糖量(mg/dl)进行比色定量,即可求出血糖值。用放射免疫测定法(RIA)对血浆中的胰岛素量(ng/ml)进行定量即可求出血中胰岛素值。其结果是,服用10mg/kg实施例4的化合物后,与未服用时的值相比,以AUC比计,胰岛素分泌量上升3倍,血糖值降达90%。从上述结果可看出,本发明的化合物具有良好的胰岛素分泌促进作用。
此外,本发明的化合物作为减肥药物或降脂剂也可能有效。
