Abstract
本发明的式(I)的茚衍生物可以选择性地调节过氧化物酶体增殖物激活受体(PPAR)的活性,其不引起不利的副作用,因此它们可用于治疗和预防由PPAR介导的疾病,例如,代谢综合征比如糖尿病、肥胖症、动脉硬化、高脂血症、高胰岛素症和高血压,炎症性疾病比如骨质疏松症、肝硬化和哮喘,以及癌。
Description
技术领域
本发明涉及一种新型茚衍生物,其可用作过氧化物酶体增殖物激活受体(PPAR)的调节剂,和其制备方法以及含有该茚衍生物作为活性成分的药物组合物。
背景技术
过氧化物酶体增殖物激活受体(PPAR)是核内激素受体超家族成员并且作为转录因子以异二聚体的形式与类视黄醇X受体(RXR)发挥调控基因表达的功能。PPAR分为三种亚型,“PPARα”、“PPAR γ”和“PPAR δ”,并且通常涉及通过控制脂肪和葡萄糖的新陈代谢维持脊椎动物中能量的体内稳态。
因此,已经有一些尝试来开发PPARα和PPAR γ完全激动剂,其用于治疗和预防由PPAR调节的疾病,例如,代谢综合征比如糖尿病、肥胖症、动脉硬化、高脂血症、高胰岛素症和高血压;炎症性疾病比如骨质疏松症、肝硬化和哮喘;和癌。
例如,已经有报道对于PPAR γ的噻唑烷-2,4-二酮(TZD)和非基于TZD的完全激动剂在非胰岛素依赖型糖尿病(NIDDM)哺乳动物模型中表现出优异的降低血液葡萄糖水平的作用(J.Med.Chem.,1999,42,3785.;Bioorg.Med.Chem.Lett.,2000,2453.;Chem.Pharm.Bull.,2002,50,1349.;Bioorg.Med.Chem.Lett.,2002,77.;J.Med.Chem.,2003,46,3581.)。
然而,也已经知道这种PPARγ完全激动剂引起不利的副作用,其包括因促进脂肪细胞的分化而引起的体重增加、心脏肥大、水肿和肝损伤。
因此,需要开发选择性PPAR调节剂(SPPARM),其能够选择性控制PPAR的活性但并不引起副作用(Molecular Cell,2001,8,737;Molecular Endocrinology,2003,17,662;Molecular Endocrinology,2002,16,2628)。

本发明的式(I)化合物可以,例如,按反应图解(I)制备:
反应图解(I)
其中,
R1-R7的含意与式(I)中的定义相同,和X是卤素。
在反应图解(I)中,式(II)化合物可以在合适的碱存在的氮环境下与具有各种取代基的烷基羟胺或它的盐酸盐一起搅拌直到式(II)化合物完全消耗以获得式(I)化合物。这时,使用2-10当量的烷基羟胺或它的盐酸盐,并且式(I)的顺式和反式化合物(几何异构体)一起被获得。可以用于该反应的理想的反应溶剂的实例是二甲基甲酰胺、硝基乙烷、甲醇或乙醇,并应用2-10当量的胺比如2,6-卢剔啶或吡啶,在50-120℃进行12-36小时,优选在压力反应器中进行。
可选择的,式(II)化合物在合适的碱存在下可以与羟胺或它的盐酸盐一起搅拌直到式(II)化合物完全消耗以获得式(III)化合物。在该反应中,使用2-10当量的羟胺或它的盐酸盐。能够用于该反应的理想的反应溶剂的实例是甲醇和乙醇,并应用2-10当量的胺比如吡啶,在20-100℃进行3-12小时。

3)可以使用通常的氧化剂将式(VIII)化合物氧化为式(II)化合物。例如,可以在溶剂比如1,4-二 烷或四氢呋喃中使用过量(5-15当量)的二氧化硒作为最优选的氧化剂在50-120℃进行7-15小时以获得式(II)的氧化化合物。
