Nitecapone (OR-462) is an orally active and short-acting catechol-O-methyltransferase (COMT) inhibitor with gastroprotective and antioxidant properties. Nitecapone (OR-462) scavenges reactive oxygen and nitric radicals and prevents lipid peroxidation.
体外研究
Nitecapone (1-100 μM) reducesd GSH (reduced glutathione) depletion induced by ROOby 11-38% and oxidation to oxidized glutathione (GSSG) by 32-45%.
体内研究
Nitecapone (30 mg/kg, ip daily for 13 days) reduces development and symptoms of neuropathic pain after spinal nerve ligation in rats.
Animal Model:
Eighty-six male Wistar rats, weighing 140-350 g.
Dosage:
30 mg/kg (3.3 mL/kg).
Administration:
IP, once daily for 13 days.
Result:
Selectively and specifically inhibits COMT in the peripheral tissues, and to some extent in the CNS for ca. 3 h.
Increased the thresholds for the mechanical stimuli and thus reduced mechanical allodynia.
Reduced the number of positive reactions of the ipsilateral paws when compared with the baselines in the nitecapone-pretreated rats.
