Synthesis and structure–activity relationships of 1,5-diazaanthraquinones as antitumour compounds
摘要:
1,5-Diazaanthraquinone derivatives were synthesized employing single and double hetero Diels-Alder strategies. Their in vitro antitumour activity was assayed using three cell lines. Some of these compounds, specially those bearing methyl or ethyl groups at the C-3,7 positions or chloro at C-4 and methyl at C-7, showed IC50 values in the 10(-8) M range for human lung carcinoma and human melanoma, which makes them attractive candidates for further development as anticancer agents.

6-(3-Indolyl)quinolinequinone derivatives gave regioselectiveDiels–Alderreactions with a variety of dienophiles, yielding polycyclic carbazole derivatives. One-pot reactions, proceeding through a cascade of reactions including regioselective Michael and Diels–Alder steps, gave heptacyclic derivatives starting from indoles and 2,5,8(1H)-quinolinetriones.
