EcPLA
Chemical compound
EcPLA, also known as N-ethyl-N-cyclopropyllysergamide or as lysergic acid ethylcyclopropylamide (LAEcP), is a psychedelic drug of the lysergamide family related to lysergic acid diethylamide (LSD). It is an isomer of LSZ and is closely related to other amide-substituted lysergamides like MiPLA. The drug has been encountered as a novel designer drug.
01Use and effects
EcPLA produces psychedelic effects in humans.
02Pharmacology
Pharmacodynamics
EcPLA has been found to interact with serotonin receptors and dopamine receptors, among other targets. It is a high potency agonist of the serotonin receptors, with its highest binding affinities at the 5-HT1A (Ki = 3.2 nM), 5-HT2B (Ki = 5.3 nM), and 5-HT5A (Ki = 8.6 nM) subtypes. Its 5-HT2A affinity is equivalent to that of LSD, while the affinity to 5-HT2C receptors is 3 times lower than LSD. It shares much of its binding profile with LSD, but does not bind to β1 or β2 adrenergic receptors as LSD does.
The drug produces the head-twitch response, a behavioral proxy of psychedelic effects, in rodents. It has about 40% of the potency of LSD in this regard.
Pharmacokinetics
The in-vitro metabolism of EcPLA has been studied.
03Chemistry
04History
EcPLA was first described in the scientific literature by a team that included Adam Halberstadt, Alexander Stratford, Jason Wallach, and David E. Nichols in 2019. It was developed by Lizard Labs. The drug was encountered online as a novel designer drug in around 2020 and became more widely available in early 2022.
