LSM-775, also known asN-morpholinyllysergamide or aslysergic acid morpholide, is apsychedelic drug of thelysergamide family related tolysergic acid diethylamide (LSD).[2]

Use and effects

[edit]

LSM-775 is lesspotent thanLSD but is reported to have some LSD-like effects at doses ranging from 75 to 700 μg and a shorterduration.[3] It may only produce weak or thresholdpsychedelic effects in humans.[4] There are claimed to be fewer signs ofcardiovascularstimulation andperipheraltoxicity with LSM-775 compared to LSD.[3][dubiousdiscuss]

Pharmacology

[edit]

Pharmacodynamics

[edit]

LSM-775 is apotentfull agonist of theserotonin5-HT1A receptor and a potentpartial agonist of the serotonin5-HT2A,5-HT2B, and5-HT2C receptors.[4] It does not produce thehead-twitch response, a behavioral proxy of psychedelic effects, in rodents.[4] However, LSM-775 can robustly increase head twitches if it is coadministered with the serotonin 5-HT1A receptorantagonistWAY-100635.[4] These findings indicate that serotonin 5-HT1A receptor activation suppresses the psychedelic-like effects of LSM-775.[4]

History

[edit]

LSM-775 was first described in thescientific literature byAlbert Hofmann and colleagues by 1955.[5]
