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.

Nitecapone is an antioxidant molecule which has been shown to protect the heart against ischemia-reperfusion injury. We investigated whether a similar effect could be detected on lung graft preservation in a porcine model of single lung transplantation. Donors received either

The aims of the present study were to assess the usefulness of the Helicobacter felis mouse model in the evaluation of antimicrobial therapies and the effect of Helicobacter infection on gastric mucosal prostaglandin E2 release. Barrier-maintained BALB/c mice were infected

To study the effect of nitecapone, a novel antioxidant, on cardiac neutrophil activation during cardiopulmonary bypass in patients. In a double-blind, placebo controlled trial, 30 male patients undergoing coronary artery bypass grafting were randomly assigned to control (crystalloid cardioplegia, n

The enzyme catechol-O-methyltransferase (COMT), which plays an important role for dopamine metabolism, is abundantly expressed in the kidney. To test whether the natriuretic effects of dopamine may be related to the rate of dopamine metabolism, rats were treated with nitecapone

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
