  Clathrodin, hymenidin and oroidin, and their synthetic analogues as inhibitors of the voltage-gated potassium channels

  摘要：

  We have prepared three alkaloids from the Agelas sponges, clathrodin, hymenidin and oroidin, and a series of their synthetic analogues, and evaluated their inhibitory effect against six isoforms of the KO subfamily of voltage-gated potassium channels, g(v)1.1-K(v)1.6, expressed in Chinese Hamster ovary (CHO) cells using automated patch clamp electrophysiology assay. The most potent inhibitor was the (E)-N-(3(2-amino-1H-imidazol-4-yl)ally1)-4,5-dichloro-1H-pyrrole-2-carboxamide (6g) with IC50 values between 1.4 and 6.1 mu M against K(v)1.3, K(v)1.4, K(v)1.5 and K(v)1.6 channels. All compounds tested displayed selectivity against K(v)1.1 and K(v)1.2 channels. For confirmation of their activity and selectivity, compounds were additionally evaluated in the second independent system against K(v)1.1-K(v)1.6 and K(v)10.1 channels expressed in Xenopus laevis oocytes under voltage clamp conditions where IC50 values against K(v)1.3K(v)1.6 channels for the most active analogues (e.g. 6g) were lower than 1 mu M. Because of the observed low sub-micromolar IC50 values and fairly low molecular weights, the prepared compounds represent good starting points for further optimisation towards more potent and selective voltage-gated potassium channel inhibitors.

  Synthesis of Marine Sponge Alkaloids Oroidin, Clathrodin, and Dispacamides. Preparation and Transformation of 2-Amino-4,5-dialkoxy-4,5-dihydroimidazolines from 2-Aminoimidazoles

  摘要：

  The preparation and transformation of 2-amino-4,5-dialkoxy-4,5-dihydroimidazolines A from 2-aminoimidazoles (AIs) is described. The oxidation of 2-aminoimidazole 8 with NCS in methanol affords cyclic guanidine adduct 9 which, upon heating, affords vinylogous AI derivative 3 and 8-aminoimidazolinone (glycocyamidine) 13. Olefin 3 comprises the core structure found in the oroidin alkaloids. Furthermore, oxidation of 8 with B-2 and DMSO affords directly alpha,beta-unsaturated imidazolinone 14 which is the key structural unit comprising the dispacamides (2). A highly facile and practical synthesis of the C11N5 marine sponge alkaloids oroidin (la), clathrodin (1c), and dispacamides (2) is outlined.

  fungal strain (Candida albicans), and oroidin was found to possess promising Gram-positive antibacterial activity. Using oroidin as a scaffold, 34 new analogues were designed, prepared and screened for their antimicrobial properties. Of these compounds, 12 exhibited >80% inhibition of the growth of at least one microorganism at a concentration of 50 µM. The most active derivative was found to be 4-phenyl-2-aminoimidazole

• A Simple and Practical Synthesis of 2-Aminoimidazoles

  A new and simple two-step procedure to synthesize 2-aminoimidazoles (2-AI's) from readily available materials has been developed. The cyclization reaction of alpha-halo ketones and N-acetylguanidine in acetonitrile (MeCN) at reflux, or in dimethylformamide (DMF) at ambient temperature, gives 4(5)-substituted and 4,5-disubstituted N-(1H-imidazol-2-yl)acetamides, which are then hydrolyzed to their respective 2-AI's. In general, the purified products were isolated in good yields. We have prepared several examples and have demonstrated the usefulness of this method by its application in the total synthesis of 8, an interesting histamine analog, and oroidin, 15, a marine natural product isolated from various sponges.
