Biochem/physiol Actions

Nitecapone is a short-acting inhibitor of catechol-O-methyltransferase (COMT). Nitecapone displays in vivo activity in peripheral tissues, but does not pentrate the blood brain barrier. The compound increases mechanical and thermal nociception, and reduces neuropathic pain in diabetic rats and in a spinal nerve ligation model.

We tested the hypothesis that recognized gastroprotective agents exert direct protection against ethanol-induced injury in isolated rat gastric mucosal cells in vitro. If protection exists, we also wanted to identify subcellular targets in the reversible and/or irreversible stages of cell

The development and progression of diabetic nephropathy is dependent on glucose homeostasis and many other contributing factors. In the present study, we examined the effect of nitecapone, an inhibitor of the dopamine-metabolizing enzyme catechol-O-methyl transferase (COMT) and a potent antioxidant

We hypothesized that antithrombotic plasma-activated protein C plays a defensive antithrombotic role during coronary ischemia and postischemic reperfusion. We evaluated protein C activation during cardiopulmonary bypass and coronary reperfusion in 20 patients undergoing coronary bypass surgery. During cardiopulmonary bypass and

Degradation of levodopa in the periphery is known to be associated with motor fluctuations and dyskinesia in Parkinson's disease (PD) patients. The enzyme catechol-O-methyltransferase (COMT) is responsible for much of this degradation. Therefore, inhibiting COMT activity is one method of
