Abstract (EN): Currently, peripheral COMT inhibitors have an important role in the treatment of Parkinson's disease, and central COMT inhibitors have a potential role in the treatment of various neuropsychiatric disorders, such as attention deficit hyperactivity disorder. Adverse reactions, low bioavailability and short elimination half-lives have prompted the development of new selective COMT inhibitors. The objective of this study was to evaluate the pharmacodynamic properties of novel tight-binding COMT inhibitors (NC, NE, NDE, NCAPE, CNCAFBn, CNCAPE, NCAFBn, CNCAPA, CNCABA and CNCAHA) and compared to standard inhibitors tolcapone and entacapone. The activity of soluble (S) and membrane bound (MB) COMT from rat liver and brain was assessed in the presence of varying concentrations of each inhibitor. NE and NC behaved most potently against liver S-COMT, and CNCAPE was the most potent inhibitor against brain MB-COMT. The cytotoxicity of tolcapone and CNCAPE in human neuroblastoma SK-N-SH cells and human liver adenocarcinoma SK-HEP-1 cells was also assessed. At lower concentrations, CNCAPE did not reduce cell viability, suggesting that CNCAPE may have a potential therapeutic role as a centrally active COMT inhibitor.
