B-193 is a serotonin 5-HT2 receptor antagonist of the β-carboline family.[1][2] It shows affinity for serotonin 5-HT2 and α1-adrenergic receptors and much lower affinity for serotonin 5-HT1 and α2-adrenergic receptors.[1] The drug also inhibits serotonin-induced contractions in the rat fundus stomach strip.[1] Conversely, it does not inhibit serotonin or norepinephrine reuptake.[2]

B-193 reverses the effects of various serotonergic agents in animals, such as the head-twitch response induced by 5-HTP and LSD and the hyperthermia induced by fenfluramine and mCPP, among various others.[1] On the other hand, it does not influence effects of most dopaminergic agents, including reserpine, levodopa, and apomorphine, though it did enhance amphetamine-induced hyperlocomotion.[2] The drug produces antidepressant-like effects in rodents and was regarded as having the profile of an atypical antidepressant.[2] The toxicity of B-193 has been studied.[3][4]

B-193 was first described in the scientific literature by 1989.[1][2]
