    摘要:
    人类微粒体细胞色素 P450 (CYP) 2A6 对尼古丁的解毒作用很大,但也能激活烟草特异性致癌物质,使其产生致突变产物。我们制备了一系列对人类 CYP2A6 活性有抑制作用的苯并呋喃和香豆素衍生物。已报道的化合物甲氧呋喃和薄荷呋喃对 CYP2A6 的活性有很强的抑制作用,其 IC50 值分别为 0.47 µM 和 1.27 µM 。合成苯并呋喃(4-甲氧基苯并呋喃:IC50=2.20 µM )和香豆素(5-甲氧基香豆素:IC50=0.13 µM 和 6-甲氧基香豆素:IC50=0.64 µM) 衍生物对 CYP2A6 的活性相当,它们比甲氧沙林和薄荷呋喃的选择性更强。这些化合物可用作设计 CYP2A6 抑制剂药物的先导化合物,以减少吸烟和与烟草有关的癌症。

  • Nitrations of 4′,5′-dihydropsoralens: A route to radiopharmaceutical precursors
    作者:Ned D. Heindel、Natalie Foster、Thankamma Varkey
    DOI:10.1002/jhet.5570230564
    日期:1986.9
    furocoumarin, methoxsalen, which yields a single nitration product, the nitration of the 4′,5′-dihydro compound generates a condition-variant mixture of three nitro products. Reduction, diazotization, and pyrrolidine-trapping of one of these, the 4′,5′-dihydro-5-nitro-8- methoxypsoralen, provides a pyrrolidine triazene precursor for radioiodination of the dihydropsoralen system.

  • 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.
