There have been substantial developments in the chemistry and biology of the acridone alkaloids in the 16years since the topic was last reviewed in this series of monographs (2000). The present survey covers the literature from mid-1999 to 2016. A brief overview of the biosynthesis of acridone alkaloids is followed by details of the occurrence and ...

Quinoline, quinazoline, and acridone alkaloids
Natural Product Reports, 1984The most interesting new alkaloids are the acridones that contain tropone rings, which have been isolated from Citrus species. Emphasis this year is again on synthesis, with highlights including the first use of copper acetylides in the synthesis of furoquinolones, the synthesis of the (1,l -dimethylallyl)quinolinone buchapine, and developments in the ...

Synthesis and biological evaluation of novel isoxazole derivatives from acridone
Archiv der Pharmazie, 2020The present study was carried out in an attempt to synthesize a new class of potential antibacterial agents. In this context, novel isoxazoles were synthesized and evaluated for their potential antibacterial behavior against four pathogenic bacterial ...

Biomimetic synthesis of acridone alkaloids
Journal of the Chemical Society, Perkin Transactions 1, 1977Cyclisations of 2′-amino-, 2′-acetylamino-, or 2′-methylamino-2-methoxybenzophenones occur in the presence of sodium hydride in dimethyl sulphoxide to give acridone alkaloids. This cyclisation has relevance to the biosynthesis of these alkaloids. An alternative cyclisation can occur, giving 4-arylquinolines or 4-arylquinolones.

Acta Crystallographica Section C Crystal Structure Communications, 1996
The crystal packing of the title compound, C 12 H 8 N 2 O, is dominated by hydrogen bonding and π-π-type interactions along the short axial direction. Each molecule is hydrogen bonded to two adjacent molecules which are part of the same stacked column. The N-H...N hydrogen bonds have an N...N distance of 2.95A.
