Effect of 6-Benzoyl-benzothiazol-2-one scaffold on the pharmacological profile of α-alkoxyphenylpropionic acid derived PPAR agonists
摘要:
A series of nitrogen heterocycles containing alpha-ethoxyphenylpropionic acid derivatives were designed as dual PPAR alpha/gamma agonist ligands for the treatment of type 2 diabetes (T2D) and its complications. 6-Benzoyl-benzothiazol-2-one was the most tolerant of the tested heterocycles in which incorporation of O-methyl oxime ether and trifluoroethoxy group followed by enantiomeric resolution led to the (S)-stereoisomer 44 b displaying the best in vitro pharmacological profile. Compound 44 b acted as a very potent full PPAR gamma agonist and a weak partial agonist on the PPAR alpha receptor subtype. Compound 44 b showed high efficacy in an ob/ob mice model with significant decreases in serum triglyceride, glucose and insulin levels but mostly with limited body-weight gain and could be considered as a selective PPAR gamma modulator (SPPAR gamma M).
同时激活过氧化物酶体增殖物激活受体(PPAR)亚型α和γ的化合物具有在单个药物活性分子中有效治疗血脂异常和2型糖尿病(T2D)的潜力。选择性添加PPARα活性有望克服选择性PPARγ激动剂经常观察到的副作用,例如水肿和体重增加,从而导致两种亚型的双重PPARα/γ激动剂均具有平衡的活性。本文中,我们报告发现,合成和优化了一系列新的带有5或6个取代的吲哚的α-乙氧基苯基丙酸。在苯甲酰基的羰基部分上掺入肟醚可以使PPARα/γ效力比等于或略大于1,就像化合物20c和21a的情况一样。化合物20c的表现出高效力在OB / OB T2D和血脂异常,类似于罗格列酮和替格列扎的小鼠模型,但与体重增加一个显著增加。与此相反,化合物21,作为双PPARα/γ活化剂小于有力20c中,显示了一个有趣的药理学特性,因为它引起在相对于体重的参考化合物的降低。
