摘要：

Two new heterocycles, pyrimido[4,5-c]carbazole and pyrimido[5,4-b]indole, were prepared in three steps from 3-aminocarbazole and 3-aminoindole, respectively. The key Friedel-Crafts intramolecular cyclization was realized under microwave irradiation using montmorillonite K-10 clay as a catalyst. The pyrimido[4,5-c]carbazole derivative shows significant micromolar IC(50) against cancer cell lines. Unlike similar carbazole and indolocarbazole compounds, the molecule does not interfere with topoisomerase activity. (C) 2010 Elsevier Ltd. All rights reserved.
