Electro-catalytic oxidation of phenacetin with a three-dimensional reactor: Degradation pathway and removal mechanism

Phenacetin is a common analgesic, anti-arthritic and anti-rheumatic drug. This study dealt with the degradation of phenacetin in alkaline media using a three-dimensional reactor with particle electrodes. Particular attention was paid to the degradation pathway and the reaction mechanism in the system. Liquid chromatography coupled with time-of-flight mass spectrometry was used to identify the intermediates. The phenacetin was observed to be firstly cut off the branch chains main by direct oxidation, and then the intermediates further degraded to ring opening products by hydroxyl radical resulting from indirect oxidation and finally mineralized to CO2, H2O. A possible removal mechanism was proposed that direct and indirect oxidation together did effect on the pollutants with oxygen.

Synthesis, spectroscopic, structural and thermal characterizations of vanadyl(IV) adenine complex prospective as antidiabetic drug agent

The vanadyl(IV) adenine complex; [VO(Adn)2]⋅SO4; was synthesized and characterized. The molar conductivity of this complex was measured in DMSO solution that showed an electrolyte nature. Spectroscopic investigation of the green solid complex studied here indicate that the adenine acts as a bidentate ligand, coordinated to vanadyl(IV) ions through the nitrogen atoms N7 and nitrogen atom of amino group. Thus, from the results presented the vanadyl(IV) complex has square pyramid geometry. Further characterizations using thermal analyses and scanning electron techniques was useful. The aim of this paper was to introduce a new drug model for the diabetic complications by synthesized a novel mononuclear vanadyl(IV) adenine complex to mimic insulin action and reducing blood sugar level. The antidiabetic ability of this complex was investigated in STZ-induced diabetic mice. The results suggested that VO(IV)/adenine complex has antidiabetic activity, it improved the lipid profile, it improved liver and kidney functions, also it ameliorated insulin hormone and blood glucose levels. The vanadyl(IV) complex possesses an antioxidant activity and this was clear through studying SOD, CAT, MDA, GSH and methionine synthase. The current results support the therapeutic potentiality of vanadyl(IV)/adenine complex for the management and treatment of diabetes.
