The effect on dopamine uptake by L-deprenyl, its structural analogues and different types of monoamine oxidase (MAO) inhibitors was investigated. Both direct [3H]dopamine uptake into rat striatal slices and binding of a specific dopamine uptake inhibitor [3H]GBR-12935 were used in the present study. L-Deprenyl exhibits a relatively weak dopamine uptake inhibitory effect in vitro, while D-deprenyl possesses a very potent inhibitory effect. The potent effect of D-deprenyl on dopamine uptake may be responsible, at least in part, for its behavioral effects and abuse liability. L-Methamphetamine, a metabolite of L-deprenyl, does not inhibit [3H]GBR-12935 binding but it reduces the retention of [3H]dopamine in striatal tissues, suggesting that it may enhance dopamine release. The MAO-A inhibitors clorgyline and brofaromine also exhibit dopamine uptake inhibitory effects. Irreversible and reversible MAO-B inhibitors, however, such as pargyline, aliphatic N-methylpropargylamines, Ro 19-6327 and MDL-72974A and MAO-A inhibitor moclobemide do not possess any appreciable inhibitory effects on dopamine uptake. Dopamine uptake is probably unrelated to the pharmacological actions of L-deprenyl.

UI	MeSH Term	Description	Entries
D008024	Ligands	A molecule that binds to another molecule, used especially to refer to a small molecule that binds specifically to a larger molecule, e.g., an antigen binding to an antibody, a hormone or neurotransmitter binding to a receptor, or a substrate or allosteric effector binding to an enzyme. Ligands are also molecules that donate or accept a pair of electrons to form a coordinate covalent bond with the central metal atom of a coordination complex. (From Dorland, 27th ed)	Ligand

D008996	Monoamine Oxidase Inhibitors	A chemically heterogeneous group of drugs that have in common the ability to block oxidative deamination of naturally occurring monoamines.

D010879	Piperazines	Compounds that are derived from PIPERAZINE.
D004298	Dopamine	One of the catecholamine NEUROTRANSMITTERS in the brain. It is derived from TYROSINE and is the precursor to NOREPINEPHRINE and EPINEPHRINE. Dopamine is a major transmitter in the extrapyramidal system of the brain, and important in regulating movement. A family of receptors (RECEPTORS, DOPAMINE) mediate its action.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
