Some effects of mazindol, an anorectic drug, on rat brain monoaminergic systems. 1977

M F Sugrue, and G Shaw, and K G Charlton

Mazindol was devoid of effect both on rat brain steady state levels of 5-HT, 5-HIAA and tryptophan and on the rate of synthesis of 5-HT in the rat brain. Mazindol had no effect on rat brain 5-HT uptake in vivo as determined by the effect of drug pretreatment on the ability of p-chloroamphetamine to lower central 5-HT levels. A large dose of mazindol caused a slight transient decrease in rat brain levels of NA and DA. Blockade of rat brain catecholamine uptake was quantified by studying drug effects on the ability of intraventricularly administered 6-hydroxydopamine to lower brain NA and DA content. Mazindol was an extremely potent inhibitor of rat brain NA uptake in vivo, being 4-5 times more potent than desipramine. Mazindol also blocked rat brain DA uptake. Doses of mazindol needed to release alpha-methyl-m-tyramine from the rat striatum were appreciably greater than the corresponding doses of d-amphetamine. The neurochemical profile of mazindol bears a much closer resemblance to that of d-amphetamine than to that of fenfluramine.

D007211	Indoles	Benzopyrroles with the nitrogen at the number one carbon adjacent to the benzyl portion, in contrast to ISOINDOLES which have the nitrogen away from the six-membered ring.
D008297	Male		Males
D008454	Mazindol	Tricyclic anorexigenic agent unrelated to and less toxic than AMPHETAMINE, but with some similar side effects. It inhibits uptake of catecholamines and blocks the binding of cocaine to the dopamine uptake transporter.	AN-448,Diestet,Mazanor,Mazindole,Sanjorex,Sanorex,Solucaps,Teronac,Teronak,AN448
D009638	Norepinephrine	Precursor of epinephrine that is secreted by the ADRENAL MEDULLA and is a widespread central and autonomic neurotransmitter. Norepinephrine is the principal transmitter of most postganglionic sympathetic fibers, and of the diffuse projection system in the brain that arises from the LOCUS CERULEUS. It is also found in plants and is used pharmacologically as a sympathomimetic.

D001921	Brain	The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.	Encephalon
D001923	Brain Chemistry	Changes in the amounts of various chemicals (neurotransmitters, receptors, enzymes, and other metabolites) specific to the area of the central nervous system contained within the head. These are monitored over time, during sensory stimulation, or under different disease states.	Chemistry, Brain,Brain Chemistries,Chemistries, Brain
D003342	Corpus Striatum	Striped GRAY MATTER and WHITE MATTER consisting of the NEOSTRIATUM and paleostriatum (GLOBUS PALLIDUS). It is located in front of and lateral to the THALAMUS in each cerebral hemisphere. The gray substance is made up of the CAUDATE NUCLEUS and the lentiform nucleus (the latter consisting of the GLOBUS PALLIDUS and PUTAMEN). The WHITE MATTER is the INTERNAL CAPSULE.

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.
