Abstract
The carbonic anhydrases (CAs, EC 4.2.1.1) represent a superfamily of widespread enzymes, which catalyze a crucial biochemical reaction, the reversible hydration of carbon dioxide to bicarbonate and protons. Human CA isoenzymes I and II (hCA I and hCA II) are ubiquitous cytosolic isoforms. In this study, a series of hydroperoxides, alcohols, and acetates were tested for the inhibition of the cytosolic hCA I and II isoenzymes. These compounds inhibited both hCA isozymes in the low nanomolar ranges. These compounds were good hCA I inhibitors (Kis in the range of 24.93-97.99 nM) and hCA II inhibitors (Kis in the range of 26.04-68.56 nM) compared to acetazolamide as CA inhibitor (Ki: 34.50 nM for hCA I and Ki: 28.93 nM for hCA II).I documenti in FLORE sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
