-Lysergic acid α-hydroxyethylamide (LSH, LAH), also known as -lysergic acid methyl carbinolamide, is an alkaloid of the ergoline family, believed to be present in small amounts in various species in the Convolvulaceae (morning glory), as well as some species of fungi. Chemistry The structure is similar to LSD, with the N,N- diethylamide group replaced by an N- (1- hydroxyethyl)amide in -lysergic acid α-hydroxyethylamide. Pharmacology LSH has an affinity for several dopamine and serotonin recetors in the human brain. LSD is a partial agonist on many dopamine and serotonin receptors, so it is highly likely that LSH is also an agonist at dopamine and serotonin receptors. LSH has an affinity for the following receptors: 5-HT2A, 5-HT2B, 5-HT2C, 5-HT6, 5-HT1D, 5-HT1A, D1 and D2. Effects One of the alkaloids in the seeds of Rivea corymbosa (Ololiuhqui), Argyreia nervosa (Hawaiian Baby Woodrose), and Ipomoea violacea (Tlitliltzin) are ergine (LSA) and isoergine (its epimer). The human activity of -lysergic acid α-hydroxyethylamide is unknown. Legality -lysergic acid α-hydroxyethylamide is unscheduled and uncontrolled in the United States, but possession and sales of it for human consumption could potentially be prosecuted under the Federal Analog Act because of its structural similarities to LSD.
