Sulfur, selenium and tellurium containing amines act as effective carbonic anhydrase activators.

A new series of β-aminochalcogenides were designed and synthesized to identify new carbonic anhydrase activator (CAA) agents as novel tools for the management of several neurodegenerative and metabolic disorders which represent a clinical challenge without effective therapies available. Some β-aminoselenides and β-aminotellurides showed effective CA activating effects and a potent antioxidant activity. CAAs may have applications for memory therapy and CA deficiency syndromes.
