title: Carbonic anhydrase and acetylcholinesterase inhibitory effects of carbamates and sulfamoylcarbamates.
abstract: Carbonic anhydrases (CA), as a family of metalloenzymes, are found in almost every type of tissue and play an important role in catalyzing the equilibration of carbon dioxide and carbonic acid. In this study, a series of carbamate derivative was synthesized, and their inhibition effects on hCA I, hCA II and acetylcholinesterase (AChE) enzymes were investigated. They were determined to be very good inhibitor against for both isoenzymes (hCA I and hCA II) and AChE. The hCA I and hCA II were effectively inhibited by the carbamate derivatives, with inhibition constants (Ki) in the range of 194.4-893.5 nM (for hCA I) and 103.9-835.7 nM (for hCA II). On the other hand, Ki parameters of these compounds for AChE enzyme inhibition were determined in the range of 12.0-61.3 nM. The results clearly showed that both CA isoenzymes and AChE were inhibited by carbamate derivatives at the nM levels.
