Abstract
Behavioural and some neurochemical effects of Ro 40-7592 (3,4-dihydroxy-4'-methyl-5-nitrobenzophenone), a new COMT inhibitor, were studied in rats and mice. Ro 40-7592 increased the effect of L-DOPA (plus benserazide) on locomotor activity, reserpine-induced hypothermia, and catalepsy induced by pimozide, haloperidol and fluphenazine. Locomotor hyperactivity induced by amphetamine or nomifensine, as well as stereotypy induced by amphetamine (but not apomorphine), were also increased by Ro 40-7592. The drug stimulated exploratory activity in the open field test. It decreased the levels of HVA and 3-MT, increased the level of DOPAC but did not change the levels of dopamine in the striatum, nucleus accumbens and frontal cortex. These results indicate that Ro 40-7592 may improve the therapy with L-DOPA (plus decarboxylase inhibitor) of Parkinson's disease.
