    天然香豆素作为β-分泌酶抑制剂的构效关系
    摘要:
    本研究证明可以评估天然香豆素(NOC)(包括简单香豆素,呋喃香豆素和吡喃香豆素)对β-分泌酶(BACE1)活性的抑制作用。在41个NOC中,一些呋喃香豆素抑制了BACE1的活性,但简单的香豆素和吡喃香豆素没有影响。最有效的抑制剂是5-香叶基氧基-8-甲氧基补骨脂素(31),IC 50值为9.9μM 。其他呋喃香豆素衍生物,例如8-香叶基氧基-5-甲氧基补骨脂素(35),8-香叶基氧基补骨脂蛋白(24)和佛手柑(18)抑制BACE1活性,IC 50值<25.0μM。通过狄克逊曲线和Cornish-鲍登地块抑制机制的分析表明,化合物18,31和35混合型抑制剂。香豆素24抑制BACE1的动力学是非竞争性抑制剂。

  • Alkoxypsoralens, Novel Nonpeptide Blockers of <i>Shaker</i>-Type K<sup>+</sup> Channels:  Synthesis and Photoreactivity
    作者:Heike Wulff、Heiko Rauer、Tim Düring、Christine Hanselmann、Katharina Ruff、Anja Wrisch、Stephan Grissmer、Wolfram Hänsel
    DOI:10.1021/jm981032o
    日期:1998.11.1
    A series of psoralens and structurally related 5,7-disubstituted coumarins was synthesized and investigated for their K+ channel blocking activity as well as for their phototoxicity to Artemia salina and their ability to generate singlet oxygen and to photomodify DNA. After screening the compounds on Ranvier nodes of the toad Xenopus Laevis, the affinities of the most promising compounds, which proved to be psoralens bearing alkoxy substituents in the 5-position or alkoxymethyl substituents in the neighboring 4- or 4'-position, to a number of homomeric K+ channels were characterized. All compounds exhibited the highest affinity to Kv1.2. 5,8-Diethoxypsoralen (10d) was found to be an equally potent inhibitor of Kv1.2 and Kv1.3, while lacking the phototoxicity normally inherent in psoralens. The reported compounds represent a novel series of nonpeptide blockers of Shaker-type K+ channels that could be further developed into selective inhibitors of Kv1.2 or Kv1.3.
