Benanserin, also known as benzyl antiserotonin (BAS), by its developmental code name MC-4788 or Sq-4788, and by its chemical name 1-benzyl-2-methyl-5-methoxytryptamine, is a serotonin receptor antagonist and described tranquilizer of the tryptamine and 5-methoxytryptamine families. [2] [1] [3] [4] It is the derivative of 5-methoxytryptamine with a benzyl group at the 1 position and a methyl group at the 2 position. [2] [3] The drug is said to be active in humans at a dose of 10 to 35 mg orally or intravenously. [1] In contrast to certain other serotonin receptor antagonists like chlorpromazine, benanserin does not antagonize the subjective effects of the serotonergic psychedelic LSD. [4] It was first described in the scientific literature by at least 1955 and was one of the first serotonin antagonists. [2] [5]
