INHIBITION OF CARBONIC ANHYDRASE I AND II WITH TOTAL ANTHOCYANINS EXTRACTED FROM SWEET CHERRY CULTIVARS

Total anthocyanins were extracted from six sweet cherry cultivars grown in Sakarya, Turkey. In vitro inhibition effects of the extracted total anthocyanins on purified carbonic anhydrase I and II were investigated using CO2 as a substrate. All the extracted total anthocyanins inhibited the activity of the human carbonic anhydrase (hCA) I and II enzymes. Among all the cultivars, 'Karakiraz' was found to be the most active on both hCA I (IC50 = 30.59 mu g/mL) and hCA II activity (IC50 = 44.52 mu g/mL). Additionally, all the cultivars have higher inhibitory activity on hCA I than hCA II.
