  A C-Ring Regioisomer of the Marine Alkaloid Meridine Exhibits Selective In Vitro Cytotoxicity for Solid Tumours

  摘要：

  9-Hydroxybenzo[b]pyrido[4,3,2-de](1,10)-phenantrolin-8-one (1), a regioisomer of the marine alkaloid meridine, was synthesized from 5,8-dimethoxy-6-nitro-4(1H)-quinolinone in eight steps and 23% overall yield. A shorter route was also investigated, based on the hetero Diels-Alder reaction between o-nitrocinnamaldehyde dimethylhydrazone and 4-halogen-6-bromo-5,8-quinolinequinones followed by reductive cyclization onto the C-5 carbonyl of the quinone. Compound 1 showed a remarkable in vitro cytotoxicity, with a pattern of selectivity towards solid rumours that is not found in the reference alkaloid, the activity against the human lung carcinoma (A-549) being particularly noteworthy. The activities of meridine and compound 1 as inhibitors of topoisomerase II were also significantly different. (C) 2001 Elsevier Science Ltd. All rights reserved.

  Two pyridoacridines, N-hydroxymethylisocystodamine (1) and neolabuanine A (2), together with the known ecionine A (3), ecionine B (4), isocystodamine (5), N-methylisocystodamine (6), 9-hydroxyisoascididemin (7), and biemnadin (8), were isolated from a marine sponge Biemna sp. Several of these compounds were shown to induce cell differentiation of K562 leukemia cells into erythrocytes. Following inspection of the NMR data, and comparison of these data with literature values, we demonstrated that neolabuanine A (2) had the structure previously reported as labuanine A (2), and that the compound initially reported under the name of labuanine A possessed the structure assigned to ecionine A (3). We found that both neolabuanine A (2) and ecionine A (3) were gradually converted to 9-hydroxyisoascididemin (7), indicating that 2 and 3 can be considered both as precursors of 7.

  A new and three known pyridoacridine alkaloids were isolated from the Indonesian marine sponge Biemna fortis as neuronal differentiation inducers against a murine neuroblastoma cell line, Neuro 2A. The chemical structure of the new compound, labuanine A (1), was determined by spectroscopic study and chemical conversion. These pyridoacridine alkaloids induced multipolar neuritogenesis in more than 50% of cells at 0.03-3 muM concentration. Compound 3, which showed the strongest neuritogenic activity among them, also induced increase of acetylcholinesterase, a neuronal marker in Neuro 2A and arrested cell cycle at the G2/M phase.
