Metabolic activation of deferiprone mediated by CYP2A6

Deferiprone (DFP) is a metal chelating agent generally used to treat patients with thalassaemia, due to iron overload in clinical settings. Studies have revealed that long-term use of DFP can induce hepatotoxicity, however, mechanisms of its toxic action remain unclear. The present studies are aimed to characterize the reactive metabolite of DFP, to define the metabolic pathway, and to determine the P450 enzymes participating in the bioactivation. A demethylation metabolite (M1) was observed in rat liver microsomal incubations. Additionally, a glutathione (GSH) conjugate (M2) and an N-acetylcysteine (NAC) conjugate (M3) were detected in microsomal incubations fortified with DFP and GSH/NAC. Biliary M2 and urinary M3 were respectively found in animals administered DFP. CYP2A6 enzyme dominated the catalysis to bioactivate DFP.

Discovery of N-Aryl-pyridine-4-ones as Novel Potential Agrochemical Fungicides and Bactericides

A series of N-aryl-pyridine-4-one derivatives were designed and synthesized using maltol and antidesmone as lead compounds, and then their fungicidal/bactericidal activities and possible mechanism of action against Colletotrichum musae were explored. Most of these compounds exhibited significant fungicidal activity in vitro. Especially, compound 23 has more than 90% inhibitory activity against nine plant pathogenic fungi at 50 μg mL-1, which is superior to azoxystrobin. Moreover, an in vivo bioassay also demonstrated that compound 23 exhibited high-efficiency broad-spectrum antifungal activity and can effectively control postharvest diseases of mango. In addition, it was found that compounds 22 and 23 can also effectively control rice bacterial leaf blight in pot experiments, which was even more effective than zhongshengmycin. Preliminary mechanism studies revealed that compound 23 may cause cell membrane and mitochondria destruction. These findings indicate that compound 23 can be used to develop potential agrochemical fungicides and bactericides.

A pantoprazole intermediate 2 - chloromethyl - 3, 4 - dimethoxy pyridine hydrochloride preparation method

The invention belongs to the technical field of medicine, and particularly relates to a preparation method of a pantoprazole intermediate 2-chloromethyl-3,4-dimethoxy pyridine hydrochloride. The preparation method comprises the following steps: using 3-hydroxyl-2-methyl-4-pyrone as a starting raw material, and then only performing five-step reaction to obtain the pantoprazole intermediate 2-chloromethyl-3,4-dimethoxy pyridine hydrochloride. The preparation method reduces the reaction steps, shortens the reaction cycle, improves the working efficiency, and increases the yield coefficient.
