    尼普拉洛尔(NIP),3,4-二氢-8-(2-羟基-3-异丙氨基)丙氧基-3-硝氧基-2H-1-苯并吡喃,在人类和犬类中被广泛代谢。为了鉴定环羟基代谢物,我们合成了顺式和反式4-羟基、5-羟基-NIP及其脱硝衍生物和7-羟基-脱硝-NIP。根据其光谱判断,反式4-羟基-和5-羟基-NIP及其脱硝衍生物对应于分离得到的环羟基代谢物。此外,在麻醉的自发性高血压大鼠中的药理学研究表明,硝氧基衍生物引起了短暂的降压反应,而硝氧基衍生物和脱硝衍生物则导致了持久的心动过缓。

    日期:——
    3-Formyl-2H-chromenes which are readily accessible through an oxa-Michael reaction of salicylaldehydes and α,β-unsaturated aldehydes undergo a smooth decarbonylation reaction upon treatment with rhodium catalysts. With our method, a great variety of functionalized chromenes is accessible in a two-step sequence from salicylaldehydes.

    公开(公告)日:2014-05-15
    The present invention provides a computer-assisted method of generating a protonophore requiring the use of a computer including a processor. The method includes: designing the protonophore, calculating, using the processor, an estimated protonophoric activity; producing the protonophore if the estimated protonophoric activity corresponds to an U 50 of about 20 μM or less; and determining the uncoupling activity of the protonophore. The present invention also provides novel protonophores that meet the above requirement and their methods of use.
    本发明提供了一种利用计算机辅助的方法来生成需要使用处理器的质子载体。该方法包括:设计质子载体,使用处理器计算估计的质子载体活性;如果估计的质子载体活性对应于大约20微米或更少的U50,则生产质子载体;并确定质子载体的解耦活性。本发明还提供了符合上述要求的新型质子载体及其使用方法。
