  Room-Temperature Aromatization of Tetrahydro-β-carbolines by 2-Iodoxybenzoic Acid: Utility in a Total Synthesis of Eudistomin U

  摘要：

  2-Iodoxybenzoic acid is a convenient reagent for the dehydrogenation of tetrahydro-beta-carbolines to their aromatic forms under mild conditions. The utility of the method was demonstrated in a total synthesis of the marine indole alkaloid eudistomin U.

  Synthesis of 1-indolyl substituted β-carboline natural products and discovery of antimalarial and cytotoxic activities

  摘要：

  A series of 1-indolyl substituted beta-carbolines including the natural products hyrtiosulawesine, pityriacitrin and pityriacitrin B were prepared via Pictet-Spengler condensation oxidation strategy from the corresponding indolyl-acetaldehydes and substituted tryptamines. Efforts to prepare the C-1 methylene-linked beta-carboline analogues for structure activity relationship studies were unsuccessful. Biological evaluation revealed two analogues (5 and 41) to exhibit weak inhibition of phospholipase A(2) (IC50 171 and 131 mu M, respectively), two to act as antioxidants (3 and 43), and 12 analogues with activity towards a chloroquine-resistant strain (FcB1) of Plasmodium falciparum (IC50 1.0-23 mu M). Testing against a panel of 60 human tumour cell lines revealed a general lack of cytotoxic effect for most of the compounds with the exception of beta-carboline 42 exhibiting modest antileukaemic activity towards the HL-60(TB) cell line (LC50 4.2 mu M). In addition, two novel structures (30 and 32) resulting from aldol condensation followed by Pictet-Spengler cyclisation displayed cytotoxicity with pronounced subpanel specificities towards colon cancer (COLO 205 and HCC-2998) cell lines.
