Furoxan nitric oxide donor coupled chrysin derivatives: Synthesis and vasculoprotection

A series of furoxan-based nitric oxide-releasing chrysin derivatives were synthesized. Pharmacological assays indicated that all chrysin derivatives exhibited in vitro inhibitory activities against aldose reductase and advanced glycation end-product formation. Some chrysin derivatives were also found to increase the glucose consumption of HepG2 cells. Furthermore, the compounds released a low amount of NO in the presence of l-cysteine (range from 0.20% to 1.89%). These hybrid furoxan-based NO donor chrysin derivatives offer a mutual prodrug design concept for the development of therapeutic or preventive agents for vascular complications due to diabetes.

A group of hybrid furoxan based nitric oxide-releasing chrysin derivatives was synthesized. All these chrysin derivatives released NO upon incubation with PBS at pH 7.4, exhibited inhibitory activities against aldose reductase and advanced glycation end-products formation in vitro. And some of them were even found to increase the glucose consumption of HepG2 cells.Figure optionsDownload as PowerPoint slide
