Electrochemical Three‐Component Synthesis of Heteroaryl Sulfonates

European Journal of Organic Chemistry, EarlyView.
An electrochemical, metal‐free three‐component strategy for direct C(sp2)─H sulfonation of electron‐rich heteroarenes using SO2 and alcohols is described. Utilizing inexpensive graphite electrodes and practical SO2 stock solutions under mild conditions, this method provides straightforward access to heteroaryl sulfonates from simple building blocks ...

Suppression of lipopolysaccharide-induced COX-2 expression via p38MAPK, JNK, and C/EBPβ phosphorylation inhibition by furomagydarin A, a benzofuran glycoside from Magydaris pastinacea

Journal of Enzyme Inhibition and Medicinal Chemistry
The phytochemical investigation of the methanol extract of the seeds of Magydaris pastinacea afforded two undescribed benzofuran glycosides, furomagydarins A-B (1, 2), together with three known coumarins.

Facile access to benzofuran derivatives through radical reactions with heteroatom-centered super-electron-donors

Nature Communications, 2023
The development of suitable electron donors is critical to single-electron-transfer (SET) processes. The use of heteroatom-centered anions as super-electron-donors (SEDs) for direct SET reactions has rarely been studied.

Effects of catechins, resveratrol, silymarin components and some of their conjugates on xanthine oxidase‐catalyzed xanthine and 6‐mercaptopurine oxidation

Journal of the Science of Food and Agriculture, Volume 105, Issue 5, Page 2765-2776, 30 March 2025.
Abstract BACKGROUND Over the past two decades, the global incidence of gout has markedly increased, affecting people worldwide. Considering the side effects of xanthine oxidase (XO) inhibitor drugs (e.g. allopurinol and febuxostat) used in the treatment of hyperuricemia and gout, the potential application of phytochemicals has been widely studied.
