Substitutive structure of a lysergamide

Lysergamides are amides of lysergic acid. Lysergamides can technically be classified as complex tryptamines, like Ibogaine.

Ergoline refers to a class of compounds derived from alkaloids of a group of fungi known as ergot in the claviceps genus. These compounds typically have strong psychedelic effects.

Chemistry

Lysergamides are polycyclic amides which have both phenethylamine and tryptamine groups embedded within their structure and a carboxamide group attached to carbon number eight. Varying the substituent attached to the nitrogen atoms has produced a variety of drugs with psychedelic effects as well as prescription drugs for treating headaches and inducing labor. Hydroxylation of the aromatic ring is one method of metabolizing lysergamides in humans and produces compounds with greater affinity to dopamine receptors.

Pharmacology

Further information: Serotonergic psychedelic

The psychedelic effects of lysergamides are believed to come from its efficacy at the 5-HT_2A receptor as a partial agonist. Lysergamides are known to have affinity for a much greater variety of receptors than other psychedelic drugs.

However, the role of these interactions and how they result in the psychedelic experience continues to remain elusive.
