Abstract

An activation study of the human carbonic anhydrase (hCA, EC 4.2.1.1) isozymes VII and XIV using a small library of natural/non-natural amino acids and aromatic/heterocyclic amines is reported. hCA VII was efficiently activated by L-/D-His, dopamine and serotonin (K(A)s of 0.71-0.93 microM). The best hCA XIV activators were histamine (K(A) of 10 nM), L-Phe, L-/D-His and 4-amino-L-Phe (K(A)s of 0.24-2.90 microM). In view of the significant expression levels of CA VII and CA XIV in the brain, selective activation of these isoforms may be useful when developing pharmacologic agents for the management of major disorders such as epilepsy and Alzheimer's disease.
