Colour Changes during the Carbamazepine Oxidation by Photo-Fenton [PDF]

open access: yes, 2021
The oxidation of aqueous solutions of carbamazepine is conducted using the Fenton reagent, combined with the photolytic action of a 150 W medium pressure UV lamp, operating at T = 40 °C.

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.

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.

Cytotoxic acridone and indoloquinazoline alkaloids from Zanthoxylum poggei [PDF]

open access: yes
Two new alkaloids, poggeicridone (1) and 2-methoxy-7,8- dehydroruteacarpine (6), together with nine known compounds, were isolated from the dichloromethane (DCM) extract of the bark of Zanthoxylum poggei (Engl.) P. G. Waterman.

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 ...

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.

Sydnone Cycloaddition Route to Pyrazole-Based Analogs of Combretastatin A4. [PDF]

open access: yes, 2016
The combretastatins are an important class of tubulin-binding agents. Of this family, a number of compounds are potent tumor Vascular Disrupting Agents (VDAs) and have shown promise in the clinic for cancer therapy.

Unravelling the Functional Diversity of Type III Polyketide Synthases in Fungi

open access: yesAngewandte Chemie, Volume 137, Issue 44, October 27, 2025.
Type III polyketide synthases (T3PKSs) produce diverse compounds of ecological and clinical importance. Here, the activity of 37 fungal T3PKSs was profiled, revealing unexpected products and generating several pharmaceutical precursors. The machine learning model trained on the activity data accurately extrapolates the predictions to other enzymes and ...

Plant-derived antimalarial agents: from crude extracts to isolated bioactive compounds [PDF]

open access: yes, 2011
Despite decades of intense research, malaria remains a deadly disease of the developing worlds. Drugresistance to limited available antimalarials, in part, has contributed to the persistence of this infectious disease.

New paradigms for understanding and step changes in treating active and chronic, persistent apicomplexan infections [PDF]

open access: yes, 2016
Toxoplasma gondii, the most common parasitic infection of human brain and eye, persists across lifetimes, can progressively damage sight, and is currently incurable. New, curative medicines are needed urgently.
