Ro5-4864 (4'-Chlorodiazepam) is a drug which is a benzodiazepine derivative, the 4'-chloro derivative of diazepam. However unlike most benzodiazepine derivatives, Ro5-4864 lacks affinity for GABAA receptors and lacks typical benzodiazepine effects,[1] instead being sedative yet also convulsant and anxiogenic in effects.[2][3][4][5] Ro5-4864 was found to be a potent ligand for the "peripheral benzodiazepine receptor",[6] later renamed to mitochondrial translocator protein 18kDa (TSPO). Interestingly despite its convulsant effects, at lower doses Ro5-4864 has proved to be neuroprotective and has become widely used for research into the role of the TSPO protein in neurotoxicity,[7][8][9][10][11][12] as well as having analgesic [13] and possible antidepressant,[14] cardioprotective and anti-cancer effects.[15][16][17][18]
