Descarboxylysergic acid
Descarboxylysergic acid (DCLA), or 8-descarboxylysergic acid, also known as 9,10-didehydro-6-methylergoline or as 6-methyl-9-ergolene, is a drug of the ergoline and partial lysergamide families related to lysergic acid and lysergamides like lysergic acid diethylamide (LSD). It is the analogue of lysergic acid in which the carboxyl group at the C8 position of the molecule has been removed.
