Design, Synthesis and biological evaluation of novel acridine-polyamine conjugates against prostate cancer [PDF]

open access: yes, 2009
Prostate cancer is the most common cause of cancer death in men, aged 85 and over. Androgen receptor, a single polypeptide with three functional domains is very important during initiation and progression of the disease.

Acridone alkaloids. X. 13C-Nuclear magnetic resonance spectra of acridone alkaloids.

open access: yesChemical and Pharmaceutical Bulletin, 1983
The 13C-nuclear magnetic resonance spectra of twenty-seven acridone alkaloids including angular pyrano [2, 3-c] acridones and linear pyrano [3, 2-b] acridones have been analyzed and assigned. The information should be useful for the structure elucidation of new acridone alkaloids.

Chemical Metabolomics: Chemical Biology Tools for Advanced Metabolism Investigations

open access: yesAngewandte Chemie International Edition, EarlyView.
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.

1-Hydroxy-3,4-dimethoxy-10-methylacridin-9-one

open access: yesIUCrData, 2020
There are two independent molecules in the asymmetric unit of the title compound, C16H15NO4, which was isolated from fruits of Zanthoxylum leprieurii. The atoms of the three rings of each molecule are close to coplanar with the largest deviations from ...

Boron Neutron Capture Therapy at a Crossroads: Translational Gap and Emerging Delivery Agents

open access: yesChemistry – A European Journal, EarlyView.
This review surveys recent advances in boron delivery agents for BNCT, emphasizing the shift from classical small molecules to multifunctional nanocarriers and theranostic systems. By integrating targeting, imaging, and therapy, next‐generation boron compounds aim to bridge the gap between (bio)chemical innovation and clinical translation.

Enzymatic synthesis of bioactive quinolones and (thio)coumarins by fungal type III polyketide synthases

open access: yesThe FEBS Journal, EarlyView.
Quinolones are valuable scaffolds for drug discovery but are rare in nature. Here, we show that two fungal enzymes, AthePKS and FerePKS, can generate 2‐quinolones and two additional heteroaromatic scaffolds. Using AthePKS, we designed an artificial enzymatic cascade towards an antimicrobial quinolone from a simple precursor and implemented it in E ...

Development of Mild Palladium‐Catalyzed N‐Arylation of Ortho‐Acylanilines in Rhamnolipid Micellar System

open access: yesChemSusChem, Volume 19, Issue 7, 14 April 2026.
Aqueous micellar catalysis using industrially sourced rhamnolipids enables efficient Pd‐catalyzed N‐arylation of o‐acylanilines at 40°C. This surfactant‐driven system offers a sustainable and more efficient alternative to organic solvents, combining broad substrate scope, low catalyst loading, and enhanced energy efficiency.

Acridone-amine D-A-D thermally activated delayed fluorescence emitters with narrow resolved electroluminescence and their electrochromic properties

open access: yesElectrochimica Acta, 2021
Acridones have found their role in luminescent materials for OLEDs. Most interestingly, showing potential as weak charge transfer thermally activated delayed fluorescence (TADF) emitters, providing narrow photoluminescence.
