Gaboxadol, also known as 4,5,6,7-tetrahydroisoxazolo(5,4-c)pyridin-3-ol (THIP), as well as by its former developmental code names LU-2-030 and OV101, is a conformationally constrained derivative of the alkaloid and Amanita muscaria constituent muscimol. It acts as a direct GABAA receptor agonist. At lower doses, the drug has sedative and hypnotic effects, and at higher doses, it has hallucinogenic effects. Gaboxadol was studied for potential medical use as a pharmaceutical drug for a variety of indications, most notably treatment of insomnia, but was ultimately never marketed.
