Acridone studies. VI. Bromination of acridones in chloroform

Australian Journal of Chemistry, 1969
In chloroform and acetic acid, N-methylacridone and methoxylated derivatives rapidly form 1 : 2 adducts with bromine, formulated as hypobromite salts. On gentle warming these decompose to the monobromo substitution product. Hydroxylated acridones appear to also add bromine to the substituted ring, forming products which are highly reactive to water and

Elucidation of chemosensitization effect of acridones in cancer cell lines: Combined pharmacophore modeling, 3D QSAR, and molecular dynamics studies

Computational Biology and Chemistry, 2018
Overexpression of P-glycoprotein (P-gp) leads to the emergence of multidrug resistance (MDR) in cancer treatment. Acridones have the potential to reverse MDR and sensitize cells.

Acridones: Strongly Emissive HIGHrISC Fluorophores

The Journal of Physical Chemistry Letters, 2021
An acridone derivative (N-methyl-difluoro-acridone, NMA-dF) is characterized with respect to its utility as an emitter in organic light emitting diodes (OLEDs). Using steady-state and time-resolved spectroscopy as well as quantum chemistry, its ability to convert singlet and triplet excitons into light was scrutinized.

The Ultraviolet Absorption Spectra of the Acridone Alkaloids. I. Compounds containing the Acridone Nucleus

Australian Journal of Scientific Research Series A: Physical Sciences, 1950
The ultraviolet spectra of the acridone alkaloids and some derivatives have been studied. The various bands in the spectra of these compounds are interpreted by starting with theoretical treatments of the spectrum of anthracene and tracing spectral changes through acridine and phenazine to acridone.

Modulation of P-glycoprotein activity by acridones and coumarins fromCitrus sinensis

Phytotherapy Research, 2007
Bioguided fractionation of the roots of Citrus sinensis (Rutaceae) led to the isolation and identification of five coumarins, namely, clausarin, suberosin, poncitrin, xanthyletin and thamnosmonin, seven acridones, namely, acrimarine B, 2 ...
