  • Preparation and antiinflammatory activity of 2- and 4-pyridones
    作者:James Benjamin Pierce、Zaven S. Ariyan、Gaye Stuart Ovenden
    DOI:10.1021/jm00344a008
    日期:1982.2
    been self-condensed to form pyridones. N-Alkylacetoacetamides give 2-pyridones, while N-arylacetoacetamides give 4-pyridones. In an attempt to develop nonacidic, nonsteroidal antiinflammatory agents, the pyridones were tested in a carrageenan-induced pedal edema assay in rats. While the 2-pyridones were not active, 9 of 17 4-pyridones tested were active, and one compound (4g) had antiinflammatory efficacy
    几种N-烷基和N-芳基乙酰乙酰胺已经自缩合形成吡啶酮。N-烷基乙酰乙酰胺产生2-吡啶酮,而N-芳基乙酰乙酰胺产生4-吡啶酮。为了开发非酸性,非甾体类抗炎药,在卡拉胶中通过大鼠角叉菜胶诱发的踏板水肿试验对吡啶酮进行了测试。虽然2-吡啶酮没有活性,但是测试的17种4-吡啶酮中有9种是活性的,一种化合物(4g)在剂量反应分析(ED50值)中具有抗炎功效。通过标准的多维观察分析法测定小鼠的LD50值,可将大多数化合物视为无毒的。
  • The Generation of a Library of ­Bromodomain-Containing Protein Modulators Expedited by Continuous Flow Synthesis
    作者:Paolo Filipponi、Ian R. Baxendale
    DOI:10.1002/ejoc.201600222
    日期:2016.4
    A continuous flow process delivering key building blocks for a series of BCP modulator libraries is reported. A dynamically mixed flow reactor emerged as a pivotal technology in both synthesis and isolation phases enabling the processing of slurries and suspensions while maintaining high productivity and reliability. Accordingly, the synthesis of common intermediates in flow were employed to further
    报告了为一系列 BCP 调制器库提供关键构建块的连续流程过程。动态混合流反应器成为合成和分离阶段的关键技术,能够处理浆液和悬浮液,同时保持高生产率和可靠性。因此,流动中常见中间体的合成被用于进一步构建基于哒唑酮的库(36 种化合物),旨在提高先导化合物的效力和选择性,同时进一步实现新 BCP 调节剂家族的构效关系研究。
