Potent 1,3,4-trisubstituted pyrrolidine CCR5 receptor antagonists: effects of fused heterocycles on antiviral activity and pharmacokinetic properties
摘要:
A series of 1,3,4-trisubstituted pyrrolidine CCR5 receptor antagonists containing a variety of fused heterocycles at the 4-position of the piperidine side chain has been discovered, which are orally bioavailable with potent anti-HIV activity. (c) 2005 Elsevier Ltd. All rights reserved.

The present invention is directed to pyrrolidine compounds of formula (I) (wherein R?1, R2, R3, R4, R5, R6, R14¿ and n are defined herein) which are useful as modulators of chemokine receptor activity. In particular, these compounds are useful as modulators of the chemokine receptors CCR-5 and/or CCR-3.
carbanion using the reaction of 3-bromo-5,7-dimethylpyrazolo[1,5-a]pyrimidine with BunLi followed by the electrophilic addition was investigated. The obtained results provide evidence for the presence of several reaction centers in the substrate, resulting in the formation of unexpected reaction products. These results offer new prospects for the functionalization of pyrazolo[1,5-a]pyrimidines and allow the
研究了使用3-溴-5,7-二甲基吡唑并[1,5-a]嘧啶与Bu n Li反应然后进行亲电加成生成碳负离子的可能性。获得的结果为底物中存在多个反应中心提供了证据,从而导致了意想不到的反应产物的形成。这些结果为吡唑并[1,5-a]嘧啶的功能化提供了新的前景,并允许制备该系列新的药理活性衍生物。所有合成化合物的结构和纯度均通过 1 H和 13 C NMR光谱、质谱、元素分析和X射线晶体学证实。
