The Theoretical Description for a Sucralose Electrochemical Cathodical Determination over a 9-9´-Diacridyl-modified Electrode

Orbital: The Electronic Journal of Chemistry, 2021
A novel electroanalytical process for sucralose determination has been theoretically suggested. Sucralose is immobilized over an acridine derivative 9-9´-diacridyl, yielding a quaternary salt, which is thereby gradually electrochemically reduced to an N-

Chemical Metabolomics: Chemical Biology Tools for Advanced Metabolism Investigations

Angewandte Chemie, Volume 138, Issue 23, 1 June 2026.
The human metabolism has been investigated for several millennia. The metabolome is known for a high complexity due to a large number of different metabolites that are present at different concentrations. Metabolomics has been developed as a field to investigate the entire human metabolome and to elucidate disease development mechanisms.

Acridone-based acetylcholinesterase inhibitors: synthesis, antioxidant activity and molecular modeling [PDF]

, 2018
Acridone is a unique naturally occurring alkaloid known to associate with several biological activities. 2,3-dimethoxy-10-methyl-10,8a-dihydroacridin-9(8aH)-one (4) and its precursor 2-((3,4-dimethoxyphenyl)methylamino)benzoic acid (3) were synthesized ...

Anthranilate N-methyltransferase, a branch-point enzyme of acridone biosynthesis

, 2008
Acridone alkaloids formed by acridone synthase in Ruta graveolens L. are composed of N-methylanthraniloyl CoA and malonyl CoAs. A 1095 bp cDNA from elicited Ruta cells was expressed in Escherichia coli, and shown to encode S-adenosyl-l-methionine ...

N-Substituted acridone alkaloids from Toddaliopsis bremekampii (Rutaceae: Toddalioideae) of south-central Africa.

, 2005
Toddaliopsins A-D, four novel 1,2,3-trioxygenated acridone alkaloids, have been isolated from the leaves of Toddaliopsis bremekampii. Toddaliopsins B-D are the first reported acridone alkaloids with substituted N-methyl groups, in the light of which the ...

Color‐Pure Organic Luminophores: Characteristics, Definitions, Physical Basis and Fundamental Design Principles

Angewandte Chemie International Edition, EarlyView.
Color‐pure all‐organic emitters, i.e., with narrow spectral characteristics, are intensively studied for high‐definition organic LEDs and multi‐color bioimaging. In order to guide targeted materials design, this educative review discusses spectral characteristics, proper definitions and units, and the physical basis of spectral broadening, to distill ...
