ClassSmall Molecule
DescriptionAn alkaloid ester extracted from the leaves of plants including coca. It is a local anesthetic and vasoconstrictor and is clinically used for that purpose, particularly in the eye, ear, nose, and throat. It also has powerful central nervous system effects similar to the amphetamines and is a drug of abuse. Cocaine, like amphetamines, acts by multiple mechanisms on brain catecholaminergic neurons; the mechanism of its reinforcing effects is thought to involve inhibition of dopamine uptake. [PubChem]

Toxicity Profile
Route of ExposureCocaine is absorbed from all sites of application, including mucous membranes and gastrointestinal mucosa. By oral or intra-nasal route, 60 to 80% of cocaine is absorbed.
Mechanism of ToxicityCocaine produces anesthesia by inhibiting excitation of nerve endings or by blocking conduction in peripheral nerves. This is achieved by reversibly binding to and inactivating sodium channels. Sodium influx through these channels is necessary for the depolarization of nerve cell membranes and subsequent propagation of impulses along the course of the nerve. Cocaine is the only local anesthetic with vasoconstrictive properties. This is a result of its blockade of norepinephrine reuptake in the autonomic nervous system. Cocaine binds differentially to the dopamine, serotonin, and norepinephrine transport proteins and directly prevents the re-uptake of dopamine, serotonin, and norepinephrine into pre-synaptic neurons. Its effect on dopamine levels is most responsible for the addictive property of cocaine.
MetabolismHepatic. Cocaine is metabolized to benzoylecgonine and ecgonine methyl ester, which are both excreted in the urine. In the presence of alcohol, a further active metabolite, cocaethylene is formed, and is more toxic then cocaine itself. Half Life: 1 hour
Toxicity ValuesOral mouse LD50 = 96 mg/kg LD50: 95.1 mg/kg (i.p, mouse) (8)
Lethal DoseNot Available
Carcinogenicity (IARC Classification)No indication of carcinogenicity to humans (not listed by IARC).
Uses/SourcesCocaine (KOE-kane) is a local anesthetic. It is applied to certain areas of the body (for example, the nose, mouth, or throat) to cause loss of feeling. This allows some kinds of examinations or surgery to be done without causing pain. (7)
Minimum Risk LevelNot Available
Health EffectsContinued use produces insomnia, hyperactivity, anxiousness, agitation and malnutrition. Overdoses can be lethal.
SymptomsIntense agitation, convulsions, hypertension, rhythm disturbance, coronary insufficiency, hyperthermia, rhabdomyolysis, and renal impairment.
TreatmentThe specific treatment of acute cocaine poisoning is the intravenous administration of a short-acting barbiturate or diazepam. Artificial respiration may be necessary. It is important to limit absorption of the drug. If entrance of the drug into circulation can be checked, and respiratory exchange maintained, the prognosis is favorable since cocaine is eliminated fairly rapidly. (9)

2. Sodium-dependent serotonin transporter
General Function:
Serotonin:sodium symporter activity
Specific Function:
Serotonin transporter whose primary function in the central nervous system involves the regulation of serotonergic signaling via transport of serotonin molecules from the synaptic cleft back into the pre-synaptic terminal for re-utilization. Plays a key role in mediating regulation of the availability of serotonin to other receptors of serotonergic systems. Terminates the action of serotonin and recycles it in a sodium-dependent manner.

5. Kappa-type opioid receptor
General Function:
Opioid receptor activity
Specific Function:
G-protein coupled opioid receptor that functions as receptor for endogenous alpha-neoendorphins and dynorphins, but has low affinity for beta-endorphins. Also functions as receptor for various synthetic opioids and for the psychoactive diterpene salvinorin A. Ligand binding causes a conformation change that triggers signaling via guanine nucleotide-binding proteins (G proteins) and modulates the activity of down-stream effectors, such as adenylate cyclase. Signaling leads to the inhibition of adenylate cyclase activity. Inhibits neurotransmitter release by reducing calcium ion currents and increasing potassium ion conductance. Plays a role in the perception of pain. Plays a role in mediating reduced physical activity upon treatment with synthetic opioids. Plays a role in the regulation of salivation in response to synthetic opioids. May play a role in arousal and regulation of autonomic and neuroendocrine functions.

7. Sodium channel protein type 5 subunit alpha
General Function:
Voltage-gated sodium channel activity involved in sa node cell action potential

12. 5-hydroxytryptamine receptor 1A
General Function:
Serotonin receptor activity
Specific Function:
G-protein coupled receptor for 5-hydroxytryptamine (serotonin). Also functions as a receptor for various drugs and psychoactive substances. Ligand binding causes a conformation change that triggers signaling via guanine nucleotide-binding proteins (G proteins) and modulates the activity of down-stream effectors, such as adenylate cyclase. Beta-arrestin family members inhibit signaling via G proteins and mediate activation of alternative signaling pathways. Signaling inhibits adenylate cyclase activity and activates a phosphatidylinositol-calcium second messenger system that regulates the release of Ca(2+) ions from intracellular stores. Plays a role in the regulation of 5-hydroxytryptamine release and in the regulation of dopamine and 5-hydroxytryptamine metabolism. Plays a role in the regulation of dopamine and 5-hydroxytryptamine levels in the brain, and thereby affects neural activity, mood and behavior. Plays a role in the response to anxiogenic stimuli.

Also regulates ion channels like the potassium channel and could modulate neurotransmitter release. Plays a role in calcium signaling through modulation together with ANK2 of the ITP3R-dependent calcium efflux at the endoplasmic reticulum. Plays a role in several other cell functions including proliferation, survival and death. Originally identified for its ability to bind various psychoactive drugs it is involved in learning processes, memory and mood alteration (PubMed:16472803, PubMed:9341151). Necessary for proper mitochondrial axonal transport in motor neurons, in particular the retrograde movement of mitochondria (By similarity).
