Flesinoxan (developmental code name DU-29373) is a potent and selective 5-HT1A receptor partial or 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. It was also developed for treatment of anxiety disorders. The drug reached phase 3 clinical trials for anxiety disorders. However, due to "management decisions", the development of flesinoxan was stopped and it was not pursued any further. In humans, flesinoxan enhances REM sleep latency, decreases body temperature, and increases ACTH, cortisol, prolactin, and growth hormone secretion. In addition, both flesinoxan and LY-178210 induce anxiety in humans.
