Studies using radioisotopes. III. The biosynthesis of acridone alkaloids

, 1969
The biosynthesis of acridone alkaloids has been investigated in Acronychia baueri and Evodia xanthoxyloides. Anthranilic acid, N- methylanthranilic acid (XI), acetate, and 4-hydroxy-N-methylquinol-2- one (X) are incorporated, and tryptophan appears not ...

Inhibition of Subgenomic Hepatitis C Virus RNA Replication by Acridone Derivatives: Identification of an NS3 Helicase Inhibitor

, 2016
We report the synthesis and structure−activity relationship (SAR) of a large series of acridones and acridone-fragment derivatives designed on the basis of the selective antihepatitis C virus (HCV) activity shown by acridone 2, previously studied as a ...

Small singlet-triplet energy gap of acridone enables longer wavelength sensitisation of europium(III) luminescence

, 2000
Incorporation of 9(10H)-acridone as a chromophore into a seven-coordinate chelating ligand allows observation of sensitised luminescence from the europium(III) complex, even with excitation wavelengths greater than 410 ...
