New isoxazolidinyl-based N-alkylethanolamines as new activators of human brain carbonic anhydrases
Journal of Enzyme Inhibition and Medicinal Chemistry, 2023 Carbonic anhydrases (CAs) are widespread metalloenzymes which catalyse the reversible hydration of carbon dioxide (CO2) to bicarbonate (HCO3−) and a proton, relevant in many physiological processes. In the last few years, the involvement of CA activation

Electrochemical Synthesis of Isoxazolines: Method and Mechanism [PDF]
Chemistry – A European Journal, 2022 Abstract An electrochemical method for the green and practical synthesis of a broad range of substituted isoxazoline cores is presented. Both aryl and more challenging alkyl aldoximes are converted to the desired isoxazoline in an electrochemically enabled regio‐ and diastereoselective reaction with electron‐deficient alkenes ...
