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.

Fluorescent ligands for the peripheral-type benzodiazepine receptor (PBR) featuring the 7-nitrobenz-2-oxa-1,3-diazol-4-yl moiety were synthesized, based on N,N-dialkyl-2-phenylindol-3-ylglyoxylamides, a potent, selective class of PBR ligands previously described by us. All the new ligands are moderately to highly potent at the PBR
