TDIQ

TDIQ (also known as 6,7-methylenedioxy-1,2,3,4-tetrahydroisoquinoline or MDTHIQ) is a drug used in scientific research, which has anxiolytic and anorectic effects in animals.[1][2] It has an unusual effects profile in animals, with the effects generalising to cocaine and partially to MDMA and ephedrine,[3] but the effects did not generalise to amphetamine and TDIQ does not have any stimulant effects.[4] It is thought these effects are mediated via a partial agonist action at Alpha-2 adrenergic receptors, and TDIQ has been suggested as a possible drug for the treatment of cocaine dependence.[5]
