The 3-pentyl-, (R)- and (S)-2-pentyl-, 2-hexyl-, and 2-heptylamides of d-lysergic acid were synthesized and evaluated in biochemical and behavioral assays for LSD-like activity. In radioligand competition studies, the (R)-lysergamides were consistently more potent than the (S)-amides in displacing [3H]ketanserin from 5-HT2A receptors in rat cortical homogenate and in displacing [3H]-8-OH-DPAT (...
A sensitive method is described to detect isolysergic acid diethylamide (iso-LSD) in urine. The compound was extracted from urine and converted to a C-8 carbanion by sodium ethoxide in ethanol. Protonation of the carbanion by water selectively produced LSD. The conversion of iso-LSD to LSD was almost quantitative (98%). The product was purified by solid-phase fractionation and acid-base separat...
Lysergic acid diethylamide (LSD) is a non-selective serotonin-receptor agonist that was first synthesized in 1938 and identified as (potently) psychoactive in 1943. Psychedelics have been used by indigenous cultures for millennia [1]; however, because of LSD's unique potency and the timing of its discovery (coinciding with a period of major discovery in psychopharmacology), it is generally rega...
D-[3H]LSD binds saturably, reversibly, and with a high affinity (KD = 10 nM) to rat brain membranes. The association and dissociation rates of binding are temperature dependent and fastest at 37 degrees C. Binding is enriched in crude microsomal (P3) membranes. D-[3H]LSD binding is stereospecific as L-LSD, the psychotropically inactive enatiomer, is 1000 times weaker than D-LSD as a displacing ...
