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。

(2RS,4R)-3-(2-(3-Pyridinyl)thiazolidin-4-oyl)indoles represent a new class of potent, orally active antagonists of platelet activating factor (PAF). The compounds were prepared by acylation of the magnesium or zinc salts of substituted indoles with (2RS,4R)-2-(3-pyridinyl)-3-(tert-butoxycarbonyl)thiazolidin-4-oyl chloride. The 3-acylindole moiety functions as a hydrolytically stabilized and conformationally
Indole compounds substituted at the 1- or 3-position by a (pyrid-3-yl)thiazolid-4-yl)alkyl-, (pyrid-3-yl)thiazolid-4-oyl)-, (pyrid-3-yl)dithiolan-4-yl)alkyl- or (pyrid-3-yl)dithiolan-4-oyl)- group are potent inhibitors of PAF and are useful in the treatment of PAF-related disorders including septic shock, respiratory distress syndrome, acute inflammation, delayed cellular immunity, parturtition, fetal lung maturation, and cellular differentiation.
