Journal of neural transmission. Supplementum, 32, 165-170 (1990-01-01)
The selective, reversible inhibitors of monoamine oxidase (MAO) moclobemide and Ro 41-1049 (selective for MAO-A), as well as of Ro 16-6491 and Ro 19-6327 (selective for MAO-B) inhibited the enzyme with an initial competitive phase, followed by a time-dependent inhibition...

Neurotoxic effects of MPTP on the nigrostriatal dopaminergic system are thought to be initiated by 1-methyl-4-phenylpyridinium (MPP+), a metabolite formed by the monoamine oxidase (MAO)-B-mediated oxidation of MPTP. We previously reported that the administration of MPTP induced apoptosis in migrating...

This study demonstrated the existence of specific binding sites for [3H]Ro 19-6327 in human platelet membranes. This compound is a novel, time-dependent inhibitor of monoamine oxidase type B (MAO-B) and is structurally closely related to [3H]Ro 16-6491. The density of...

The N-methyl-D-aspartate receptor complex appears to play an important role in processes of learning and memory. The presence of a glycine modulatory site at this complex has recently been established and suggests that glycinergic neurotransmission may influence these cognitive functions....

Journal of medicinal chemistry, 36(24), 3968-3970 (1993-11-26)
A series of halo- and nitro-substituted analogues of N-(2-aminoethyl)benzamide has been synthesized. All of the compounds are competitive, time-dependent inhibitors of monoamine oxidase-B (MAO-B), but upon dialysis complete return of enzyme activity is observed for all compounds. Therefore, these are...
