Flesinoxan (DU-29,373) is a potent and selective 5-HT_1A receptor partial/near-full agonist of the phenylpiperazine class.^[1]^[2]^[3] Originally developed as a potential antihypertensive drug,^[1]^[2]^[4] flesinoxan was later found to possess antidepressant and anxiolytic effects in animal tests.^[5]^[6] As a result, it was investigated in several small human pilot studies for the treatment of major depressive disorder, and was found to have robust effectiveness and very good tolerability.^[7]^[8] However, due to "management decisions", the development of flesinoxan was stopped and it was not pursued any further.^[9]

In patients, flesinoxan enhances REM sleep latency, decreases body temperature, and increases ACTH, cortisol, prolactin, and growth hormone secretion.^[2]^[8]
