1-(2-furoyl)-lysergic acid diethylamide (1F-LSD, SYN-L-005) is a novel analog of the recently detected recreational drug 1-(thiophene-2-carbonyl)-LSD (1T-LSD). Both substances are N1-acylated LSD derivatives that bind to the 5-HT2A receptor, the primary site of action for psychedelic drugs. In C57BL/6J mice, 1F-LSD and 1T-LSD induced the head-twitch response, a 5-HT2A-mediated behavior, and were hydrolyzed to LSD after administration. These findings indicate that both compounds exhibit LSD-like properties and likely act as prodrugs for LSD, releasing the active drug in the body.
