Benzodiazepines – diazepam/alprazolam: bind with second site on GABA(A)

receptor – indirect agonists
 Effective anxiolytics
 Zolpidem and eszopiclone are related drugs
 Barbiturates: bind with third binding site – indirect agonists
 Alcohol and steroids bind with other sites
GABA transporters: remove GABA from the synapse
 Tiagabine: GABA transporter antagonist used to increase its availability
 Vigabatrin: blocks activity of GABA aminotransferase, which breaks down
GABA

Acetylcholine pathways
1. Dorsolateral pons: role in REM sleep
2. Basal forebrain: activation of cerebral cortex and facilitation of learning
3. Medial septum: control electrical rhythms of hippocampus and modulate its
functions < memory formation
ACh is composed of two precursors – choline acetyltransferase (ChAT) is required to
produce ACh from the precursors
Vesicle ACh transporter: loads and stores ACh into vesicles
 Botulinum toxin prevents ACh release
 Black widow spider venom: stimulates ACh release
Ionotropic ACh receptor: stimulated by nicotine – nicotinic receptor
 Curare: blocks nicotinic receptors
Metabotropic ACh receptor: stimulated by muscarine – muscarinic receptor
 Atropine: blocks muscarinic receptors
ACh is deactivated by acetylcholinesterase (AChE)
 Neostigmine: AChE inhibitor
After being broken down, only choline is recycled
Hemicholium-3: blocks choline transporter and reduces rate of ACh production

The monoamines
Catecholamines: dopamine (DA), norepinephrine, epinephrine
Indolamine: serotonin
Ethylamine: histamine
Dopamine pathways:
(1) Nigrostriatal system: cell bodies located in substantia nigra and project axons to
the neostriatum
(2) Mesolimbic system: cell bodies located in ventral tegmental area and project
axons to several parts of the limbic system
(3) Mesocortical system: cell bodies located in ventral tegmental area and axons
project to prefrontal cortex
Degeneration of dopaminergic neurons > Parkinsons’s
Chlorpromazine: block D2 receptors, dopamine inhibition
Apomorphine: acts as an agonist and antagonist for dopamine, depending on the
dose
Dopamine transporters: responsible for removing dopamine from the synapse
Amphetamine and methamphetamine: block dopamine/norepinephrine reuptake
and cause the transporters for them to run in reverse
Ritalin/cocaine: simply block reuptake
