Acridone is an organic compound based on the acridine skeleton, with a carbonyl group at the 9 position.

Synthesis and structure

The molecule is planar. Optical spectra reveal that the keto tautomer predominates in the gas-phase and in ethanol solution.^[1]

Acridone can be synthesized by heating fenamic acid.^[2]

History

One of the first who were able to prove the compound's existence was Karl Drechsler, Student of G. Goldschmiedt, at the k.u.k. Universität Wien (Vienna, Austria) in 1914.^[3]

Derivatives

Acridone constitutes the scaffold of some synthetic compounds with diverse pharmacological activities. 3-Chloro-6-(2-diethylamino-ethoxy)-10-(2-diethylamino-ethyl)-acridone has shown promise as an antimalarial drug.^[4]^[5]
