Application

4′-Chlorodiazepam has been used as a translocator protein ligand in mitochondrial functional studies. It has also been used to investigate its protective effects on glucose deprived T98G astrocyte cell lines.

Biochem/physiol Actions

4′-Chlorodiazepam (Ro5-4864) is a potent selective ligand for the mitochondrial translocator protein 18kDa (TSPO), formerly known as the peripheral benzodiazepine receptor (PBR). Ro5-4864 does not bind to GABA(A) receptors and lacks typical benzodiazepine effects, but has been found to be neuroprotective in several studies.
