French researchers have developed a peptide inhibitor of TREK-1 that they think produces antidepressant effects much faster than marketed selective serotonin reuptake inhibitors.1 NeuroSearch A/S is now considering moving into lead optimization with an internal effort to identify small molecule TREK-1 inhibitors.
