  发现新型吲唑衍生物作为双重血管紧张素II拮抗剂和部分PPARγ激动剂

  摘要：

  描述了吲哚衍生物作为双重血管紧张素II 1型（AT 1）受体拮抗剂和部分过氧化物酶体增殖物激活的受体-γ（PPARγ）激动剂的鉴定。 从替米沙坦开始，我们先前曾描述过吲哚衍生物是非常有效的部分PPARγ激动剂，但AT 1受体拮抗剂的活性却下降了。 新的中央支架的设计，合成和评估使我们发现了吡唑并吡啶，然后吲唑衍生物提供了具有所需双重活性的新系列。 在这些新化合物中，有38种是 大鼠中具有良好口服生物利用度的有效AT 1受体拮抗剂（IC 50  = 0.006μM）和部分PPARγ激动剂（EC 50 = 0.25μM，最大40％）。 在高血压（SHR）和胰岛素抵抗（Zucker fa / fa rat）的两个临床前模型中证实了化合物38的双重药理作用。

  Synthesis and biological evaluation of 3-amino-2-pyrones as selective cyclooxygenase-1 (COX-1) inhibitors

  摘要：

  A group of 3-amino-2-pyrones were synthesized and their biological activities were evaluated for inhibiting cyclooxygenase (COX) activity. This study has led to the identification of COX-1-selective inhibitors. Among the tested compounds, the compound 5j exhibited the most potent COX-1 inhibitory activity (IC50 = 19.32 mu g/mL) and COX-1 selectivity index (SI = 41.98). (C) 2013 Qing-Fa Zhou.

  approach is based on the Michael addition of N-(diphenylmethylene)glycinates to various alkynyl ketones, followed by lactonization using 10 mol% sodium hydroxide as catalyst. Aromatic and aliphatic alkynyl ketones were converted into the corresponding 3-amino-2-pyrone derivatives in moderate to high yields. When methyl propiolate was submitted to the reaction, α,β-dehydroamino acids were formed in good

• Cycloaddition of Alkynyl Ketones with <i>N</i>-Tosylimines Catalyzed by Bu₃P and DMAP: Synthesis of Highly Functionalized Pyrrolidines and Azetidines

  日期：2008.11.7

  Cycloadditions of alkynyl ketones with N-tosylimines catalyzed by Lewis bases to synthesize azetidines and pyrrolidines were systematically described. In the reaction of alkynyl ketones with N-tosylimines catalyzed by Bu3P at room temperature in toluene, highly functionalized pyrrolidines were formed in good to excellent yields. When DMAP was used in place of Bu3P as catalyst to facilitate the cycloaddition, completely substituted azetidines were produced in moderate to good yields in CH2Cl2. Both cyclization reactions proceeded smoothly with complete stereoselectivity. The scope and limitations of these cycloadditon reactions were also investigated.

  angiotensin II type 1 (AT1) receptor antagonists and partial peroxisome proliferator-activated receptor-γ (PPARγ) agonists is described. Starting from Telmisartan, we previously described that indole derivatives were very potent partial PPARγ agonists with loss of AT1 receptor antagonist activity. Design, synthesis and evaluation of new central scaffolds led us to the discovery of pyrrazolopyridine then
