Selenols: a new class of carbonic anhydrase inhibitors

Stable aryl selenols were obtained through a convenient procedure. Selenols represent a new chemotype acting as carbonic anhydrase inhibitors (CAIs), inhibiting four human isoforms, CAs I, II, VII and the tumor-associated CA IX. X-ray crystallographic, physical and computational studies provided insights into the binding mode of this conceptually new class of CAIs.
