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 ...

Synthesis of New Acridone Derivatives, Inhibitors of NS3 Helicase, Which Efficiently and Specifically Inhibit Subgenomic HCV Replication

, 2016
A new goup of acridone derivatives, obtained by reaction of acridone-4-carboxylic acid derivatives with aromatic amines, was tested to determine the inhibitory properties toward the NS3 helicase of hepatitis C virus (HCV). Six compounds inhibited the NS3

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 ...

Lewis Acid Promoted Hetero [2 + 2] Cycloaddition Reactions of Aldehydes with 10-Propynyl-9(10H)-acridone. A Highly Stereoselective Synthesis of Acrylic Acid Derivatives and 1,3-Dienes Using an Electron Deficient Variant of Ynamine

, 2016
Reactivities of 10-propynyl-9(10H)-acridone toward various aldehydes in BF3·Et2O-promoted hetero [2 + 2] cycloaddition reactions are described here. This electron deficient variant of ynamine is more stable and easier to handle than most ynamines but ...
