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.

Diabetes, 49(8), 1381-1389 (2000-08-03)
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

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

Kidney international, 52(3), 742-747 (1997-09-18)
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

Graphical methods to analyze tracer time-course data allow reliable quantitation of the rate of incorporation of tracer from plasma into a "trapped" kinetic component, even when the details of the kinetic model are unknown. Applications of the method over long
