(-)Deprenyl in perspective: prophylaxis for Parkinson's disease? 1986

M Sandler

Idiopathic Parkinson's disease may derive from the action of an environmental 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-like compound. Monoamine oxidase (MAO) B converts MPTP to an actual neurotoxin, 1-methyl-4-phenylpyridinium (MPP+) whilst prior administration of an MAO B inhibitor, (-)deprenyl, prevents the conversion. There is preliminary evidence that this drug can interrupt the pathological process in Parkinson's disease and prolong life expectancy. Thus, markers should be sought to identify the premorbid parkinsonian condition, prior to long-term (-)deprenyl treatment. Possibly approaches are by monitoring putative overactivity of the dopamine degrading enzymes, phenolsulphotransferase and MAO B, narrowing the field down further by PET-scan after administering a positron-emitting dopa analogue, 6-18F-labelled dopa.

UI	MeSH Term	Description	Entries
D008995	Monoamine Oxidase	An enzyme that catalyzes the oxidative deamination of naturally occurring monoamines. It is a flavin-containing enzyme that is localized in mitochondrial membranes, whether in nerve terminals, the liver, or other organs. Monoamine oxidase is important in regulating the metabolic degradation of catecholamines and serotonin in neural or target tissues. Hepatic monoamine oxidase has a crucial defensive role in inactivating circulating monoamines or those, such as tyramine, that originate in the gut and are absorbed into the portal circulation.

D010300	Parkinson Disease	A progressive, degenerative neurologic disease characterized by a TREMOR that is maximal at rest, retropulsion (i.e. a tendency to fall backwards), rigidity, stooped posture, slowness of voluntary movements, and a masklike facial expression. Pathologic features include loss of melanin containing neurons in the substantia nigra and other pigmented nuclei of the brainstem. LEWY BODIES are present in the substantia nigra and locus coeruleus but may also be found in a related condition (LEWY BODY DISEASE, DIFFUSE) characterized by dementia in combination with varying degrees of parkinsonism.

D010302	Parkinson Disease, Secondary	Conditions which feature clinical manifestations resembling primary Parkinson disease that are caused by a known or suspected condition. Examples include parkinsonism caused by vascular injury, drugs, trauma, toxin exposure, neoplasms, infections and degenerative or hereditary conditions. Clinical features may include bradykinesia, rigidity, parkinsonian gait, and masked facies. In general, tremor is less prominent in secondary parkinsonism than in the primary form.
