DescriptionAgroclavine is a naturally occuring alkaloid of the ergoline family. As it is derived from dimethylergoline, it is referred to as a clavine. Like other ergoline alkaloids, it occurs in various species of vines of the Convolvulaceae (morning glory) family and in some species of lower fungi. Long term exposure to some ergoline alkaloids can cause ergotism, a disease causing convulsive and gangrenous symptoms. (6)

Toxicity Profile
Route of ExposureOral, dermal, inhalation, and parenteral (contaminated drugs). (5)
Mechanism of ToxicityErgoline alkaloids tend to act as a group, producing complex and variable effects of partial agonism or antagonism at adrenergic, dopaminergic, and serotonergic receptors. Variables relating to these effects are influenced by the agent, dosage, species, tissue, physiological, and endocrinological state, and experimental conditions. In particular, ergoline alkaloids have been shown to have the significant affinity towards the 5-HT1 and 5-HT2 serotonin receptors, D1 and D2 dopamine receptors, and alpha-adrenergic receptors. This can result in a number of different effects, including vasoconstriction, convulsions, and hallucinations. (2, 3, 4)

Minimum Risk LevelNot Available
Health EffectsIngestion of ergoline alkaloids is known to cause the disease ergotism. Ergotism occurs in two forms, gangrenous and convulsive, likely depending on the different kinds and amounts of ergoline alkaloids present. (1)
SymptomsConvulsive ergotism can cause painful seizures and spasms, diarrhea, paresthesias, itching, headaches, nausea and vomiting. Usually the gastrointestinal effects precede the central nervous system effects. As well as seizures there can be hallucinations and mental effects including mania or psychosis. Gangrenous ergotism causes dry gangrene as a result of vasoconstriction induced in the more poorly vascularized distal structures, such as the fingers and toes. Symptoms include desquamation, weak periphery pulse, loss of peripheral sensation, edema and ultimately the death and loss of affected tissues. (7)
TreatmentTreatment for ergotism consists of vasodilators, anticoagulants and low molecular weight dextrans. If necessary, a sympathetic nerve blockade may be carried out, such as brachial plexus blockade. Temporary sedation (e.g. haloperidol) will be necessary in hallucination and diazepam is used for convulsions. There is no specific antidote. (8)

General Function:
Virus receptor activity
Specific Function:
G-protein coupled receptor for 5-hydroxytryptamine (serotonin). Also functions as a receptor for various drugs and psychoactive substances, including mescaline, psilocybin, 1-(2,5-dimethoxy-4-iodophenyl)-2-aminopropane (DOI) and lysergic acid diethylamide (LSD). Ligand binding causes a conformation change that triggers signaling via guanine nucleotide-binding proteins (G proteins) and modulates the activity of down-stream effectors. Beta-arrestin family members inhibit signaling via G proteins and mediate activation of alternative signaling pathways. Signaling activates phospholipase C and a phosphatidylinositol-calcium second messenger system that modulates the activity of phosphatidylinositol 3-kinase and promotes the release of Ca(2+) ions from intracellular stores. Affects neural activity, perception, cognition and mood. Plays a role in the regulation of behavior, including responses to anxiogenic situations and psychoactive substances. Plays a role in intestinal smooth muscle contraction, and may play a role in arterial vasoconstriction.(Microbial infection) Acts as a receptor for human JC polyomavirus/JCPyV.
