  Alkoxypsoralens, Novel Nonpeptide Blockers of Shaker-Type K⁺ Channels:  Synthesis and Photoreactivity

  摘要：

  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.

• Structural modification of a specific antimicrobial lead against Helicobacter pylori discovered from traditional Chinese medicine and a structure–activity relationship study

  Psoralen (1a) was found to be a specific and potent antimicrobial lead against Helicobacter pylori (H. pylori) from a traditional Chinese medicine (TCM) in the bioassay directed isolation. A series of structurally diverse analogues of la were thus designed and synthesized to improve the antimicrobial potency, some of which showed more potent activities than the lead compound (1a) against H. pylori. Among them, compound 25a is 16-fold stronger (MIC = 0.39 mu g/mL) than 1a (MIC = 6.25 mu g/mL), and is even potent than the positive control metronidazole (MIC = 0.50 mu g/mL). The in vitro antimicrobial activities against H. pylori of these structurally diverse analogues based on the scaffold of la have also led to an outline of structure-activity relationship.
