  Beta-carboline alkaloids derived from the ascidian Synoicum sp.

  摘要：

  Six beta-carboline alkaloids (1-6) of the eudistomin Y class were isolated from the Korean ascidian Synoicum sp. These compounds were chemically converted to a known compound, eudistomin Y-1 (7) and six new derivatives, designated eudistomins Y-8-Y-13 (8-13). Several of these natural and synthetic compounds exhibited moderate to significant antimicrobial activity, weak cytotoxic activity, and inhibitory activities toward sortase A, isocitrate lyase, and Na+/K+-ATPase. Structure-activity relationships were also deduced. (C) 2012 Elsevier Ltd. All rights reserved.

  Eudistomin Y class compounds are a series of β-carbolines which was originally isolated from a marine turnicate or ascidian near the South Korea Sea. These compounds contain bromo-substituted groups, which is one of the typical characters of marine natural products. We report herein the chemical synthesis and biological evaluation of seven new β-carboline-based metabolites, Eudistomins Y1–Y7, and their hydroxyl-methylated phenyl derivatives. Using bromo-substituted tryptamines and bromo-substituted phenylglyoxals as the key intermediates, Eudistomins Y1–Y7 and their derivatives were synthesized via the acid-catalyzed Pictet-Spengler reaction and fully characterized by 1H- and 13C-NMR and mass spectroscopy. Biological studies revealed that all of the compounds showed moderate growth inhibitory activity against breast carcinoma cell line MDA-231 with IC50 of 15–63 μM and the inhibitory activities of hydroxyl-methylated phenyl products were higher than that of the corresponding natural products Eudistomins Y1–Y7.

  Multi‐birds with one stone: A cascade coupling strategy was developed for the synthesis of β‐carbolines. The method can direct the synthesis of β‐carboline and isoquinoline‐containing natural products with high yields. Moreover, this protocol can also be further applied towards the total synthesis of natural products fascaplysin and papaverin (see scheme).
