What is "flesinoxan"

n. A piperazine drug with potential applications as an antidepressant and anxiolytic.

Flesinoxan (DU-29,373) is a potent and selective 5-HT receptor partial/near- full agonist of the phenylpiperazine class. Originally developed as a potential antihypertensive drug, flesinoxan was later found to possess antidepressant and anxiolytic effects in animal tests. 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. Unfortunately however, due to "management decisions", the development of flesinoxan was stopped and it was not pursued any further.

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