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。

Several 5- and 6-acylindoles have been synthesized in good yield by means of palladium catalyzed cross-coupling reactions between acidchloride derivatives and 5- or 6-tributylstannylindoles to give useful intermediates for the synthesis of analogues of biologically and pharmacologically active molecules.

Aromatic organotin(IV) compounds are a valuable class of reagents widely used in cross-coupling reactions. However, the toxicity of the most popular tributyl-substituted arylstannanes, combined with complicated methods for their synthesis, imposes serious limitations. Herein, we report an approach to accessing aryl organotin(IV) reagents directly from aryl halides and cheap inorganic tin(II) acetate

The stannylation of indole derivatives proceeds in good yields under palladium catalysis (5 mol %) without protection of the indolic nitrogen. The general utility of both PdCl2(PhCN)(2)/PCy3 and Pd(2)dba(3)/PCy3 as catalytic systems for the stannylation of three indole derivatives, with varying degrees of electron density, is presented.

Effect of Oxime Ether Incorporation in Acyl Indole Derivatives on PPAR Subtype Selectivity
balanced activity for both subtypes. Herein we report the discovery, synthesis, and optimization of a new series of α‐ethoxyphenylpropionic acid bearing 5‐ or 6‐substituted indoles. The incorporation of oxime ethers on the carbonyl portion of the benzoyl group can bring the PPARα/γ potency ratio equal to or slightly greater than one, as is the case for compounds 20 c and 21 a. Compound 20 c shows high efficacy
