Lometraline (INN; developmental code name CP-14,368) is a drug and an aminotetralin derivative.[1] A structural modification of tricyclic neuroleptics, lometraline was originally patented by Pfizer as an antipsychotic, tranquilizer, and antiparkinsonian agent.[2][3] However, it was instead later studied as a potential antidepressant and/or anxiolytic agent, though clinical studies revealed no psychoactivity at the doses used and further investigation was suspended.[1][4][5] Further experimental modifications of the chemical structure of lometraline resulted in the discovery of tametraline, a potent inhibitor of the reuptake of dopamine and norepinephrine, which in turn led to the discovery of the now widely popular antidepressant sertraline, a selective serotonin reuptake inhibitor (SSRI).[6]

The precursor ketone can undergo a Mannich reaction with pyrrolidine to yield CID:12348935. This specific agent had analgesic activity in the same range as morphine and was not antagonized by naloxone.[7][8]
