| Name | Nitecapone |
| Description | Nitecapone is a reversible inhibitor of S-COMT (IC50 values of 300 nM in rat liver) |
| Animal Research | Used single and repeated administration of a peripherally restricted, short-acting (nitecapone) and also a centrally acting (3,5-dinitrocatechol, OR-486) COMT inhibitor.?We also tested CGP 28014, an indirect inhibitor of COMT enzyme.?Effects of OR-486 on thermal nociception were also studied in COMT deficient mice.?Effects on spinal pathways were assessed in rats given intrathecal nitecapone[2]. |
| In vitro | At high micromolar to millimolar concentrations in in vitro research studies, nitecapone is an effective antioxidant, nitric oxide radical scavenger, and iron chelator that can protect cells from lipid peroxidation[1] |
| In vivo | After single administration, both?nitecapone?and OR-486 reduced mechanical nociceptive thresholds and thermal nociceptive latencies (hot plate test) at 2 and 3 h, regardless of their brain penetration. These effects were still present after chronic treatment with COMT inhibitors for 5 days. Intraplantar injection of carrageenan reduced nociceptive latencies and both COMT inhibitors potentiated this reduction without modifying inflammation. CGP 28014 shortened paw flick latencies. OR-486 did not modify hot plate times in Comt gene deficient mice. Intrathecal?nitecapone?modified neither thermal nor mechanical nociception[2]. |
