Tolcapone, an inhibitor of catechol O-methyltransferase, counteracts memory deficits caused by bilateral cholinotoxin lesions of the basal nuclei of Meynert

Repeated administration of tolcapone, an inhibitor of catechol-O-methyltransferase, was able to partially restore the memory deficits caused by bilateral cholinotoxin (AF64A) lesions in the basal magnocellular nuclei of Meynert. The 2-week tolcapone treatment (3 mg kg, once a day) was started 24 h b...

description Repeated administration of tolcapone, an inhibitor of catechol-O-methyltransferase, was able to partially restore the memory deficits caused by bilateral cholinotoxin (AF64A) lesions in the basal magnocellular nuclei of Meynert. The 2-week tolcapone treatment (3 mg kg, once a day) was started 24 h before toxin infusion and the last injection was given 24 h before the first avoidance test. The beneficial action of tolcapone may be related to anti-oxidant properties of nitrocatechols.
