NBOMe-LAD, also known as LSD-NBOMe, is a serotonin receptor modulator and putative psychedelic drug of the lysergamide family related to lysergic acid diethylamide (LSD). [1] It is the N-(2-methoxybenzyl) (NBOMe) derivative of LSD. [1]

Pharmacology

Pharmacodynamics

NBOMe-LAD is known to act as an agonist of the serotonin 5-HT2A receptor and to interact with other receptors, but shows dramatically reduced potency compared to LSD in vitro . [1] At the serotonin 5-HT2A receptor, it had 37-fold lower affinity, 148-fold lower activational potency in terms of calcium release, and around half the maximal efficacy in terms of calcium release relative to LSD. [1] On the other hand, NBOMe-LAD had only about 4-fold lower potency in terms of β-arrestin recruitment along with similar activational efficacy for this pathway relative to LSD. [1]

NBOMe-LAD produces the head-twitch response, a behavioral proxy of psychedelic effects, in rodents, but with greatly reduced potency and maximal efficacy relative to PRO-LAD and analogues. [1] Its ED50 Tooltip median effective dose for inducing the head-twitch response was 13-fold lower than that of PRO-LAD and its maximal effect was about one-third that of PRO-LAD. [1] However, the most efficacious dose of NBOMe-LAD was 3.2 mg/kg whereas that of PRO-LAD was 1 mg/kg. [1]

Pharmacokinetics

NBOMe-LAD showed much faster metabolism than LSD in human and rat liver microsomes in vitro . [1]

History

NBOMe-LAD was first described in the literature by 2022. [1] It was described in a patent by Andrew Kruegel and Gilgamesh Pharmaceuticals. [1] Various other NBOMe-type analogues of LSD and related compounds were also described. [1]
