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 ...

Aza-aromatic polycycles based on triphenylene and acridine or acridone: synthesis and properties

, 2021
International audienceAcridine- and acridone-based polycyclic aromatics were prepared by using as the key steps a copper-catalysed N-arylation of 2-aminobenzaldehyde, 2-aminophenones, or ethyl 2-aminobenzoate with 2-iodotriphenylene, and an acid-mediated

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

, 2009
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 ...

Anti-Cancer Effect of Tacrine-Coumarin Derivatives on Diverse Human and Mouse Cancer Cell Lines

Acta Chimica Slovenica, 2018
Acridine derivatives were first used as antibacterial and antiparasitic agents, later as antimalarial and anti-HIV drugs, and now as potentially anti-cancer agents due to their high cytotoxic activity.
