Chemical Metabolomics: Chemical Biology Tools for Advanced Metabolism Investigations

open access: yesAngewandte 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.

Functionalization of 4-bromobenzo[c][2,7]naphthyridine via regioselective direct ring metalation. A novel approach to analogues of pyridoacridine alkaloids

open access: yesBeilstein Journal of Organic Chemistry, 2019
Readily available 4-bromobenzo[c][2,7]naphthyridine undergoes regioselective direct ring metalation at C-5 with TMPMgCl∙LiCl at −40 °C. Quenching with various electrophiles gives a broad range of 5-substituted products, which are building blocks for the ...

Investigation of Dual Stage Acridones as a Potent Malaria Treatment

open access: yes, 2015
The need for potent antimalarials to prevent the emergence of drug resistant Plasmodium falciparum is urgent. Discovery of novel acridone chemotypes have shown promise for a new antimalarial drug treatment.

A Metallosupramolecular Receptor for Squaraine Dyes Enabling Ultrafast Dark Resonance Energy Transfer

open access: yesAngewandte Chemie, Volume 138, Issue 11, 9 March 2026.
A metallosupramolecular receptor binds squaraine dyes with high affinity and enables efficient dark resonance energy transfer (DRET) that generates bright near‐infrared emission with large pseudo‐Stokes shifts. ABSTRACT A metal‐organic cage was obtained by combining acridone‐based dipyridyl ligands with Pd2+ ions. The cage acts as a potent receptor for

One-Pot Synthesis of 1‑Hydroxyacridones from para-Quinols and ortho-Methoxycarbonylaryl Isocyanates

open access: yes, 2020
A variety of substituted acridones were synthesized via a one-pot, metal-free cascade reaction. In this event, the DBU-mediated addition between quinols and ortho-methoxycarbonylaryl isocyanates formed a bicyclic oxazolidinone, followed by a sequence of ...

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

open access: yesAngewandte 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 ...

Theoretical Design of Acridone-Core Energetic Materials: Assessment of Detonation Properties and Potential as Insensitive, Thermally Stable High-Energy Materials

open access: yesChemEngineering
In this study, we investigated the impact of incorporating energetic substituents such as –NO2, –NH2, –Cl, –F, N-methyl-N-nitro (CH3–N–NO2), and picryl on the detonation performance and stability of acridone-based compounds.

N‐Aryl Acridone Derivatives as Effective Catalysts for Energy Transfer Reactions

open access: yesChemistry – A European Journal, EarlyView.
Acridones derivatives have high triplet energy, are simple accessible, and could be used in challenging [2+2] ENT reactions. ABSTRACT Organic photocatalysts capable of promoting high‐energy triplet energy transfer (EnT) remain limited, particularly for demanding [2+2] photocycloaddition reactions.

Stereoretentive Nucleophilic Aromatic Substitution Accesses Atropisomeric 4‐Amino‐N‐Arylquinolinium Salts

open access: yesChemistry – A European Journal, EarlyView.
Quinolin‐4‐ones were converted to chloroquinolinium salts, allowing formation of axially chiral aminoquinolinium salts via an enantioretentive SNAr reaction with a variety of amine nucleophiles. The salts have a high rotational barrier, with a racemization half‐life of ∼1000s of years.

Palladium/Copper Co-catalyzed Oxidative C–H/C–H Carbonylation of Diphenylamines: A Way To Access Acridones

open access: yes, 2016
An efficient palladium/copper co-catalyzed oxidative double C­(sp2)–H functionalization/carbonylation of diphenylamines for synthesis of acridones has been developed. This method utilizes readily available starting materials and mild reaction conditions.
