Application

Etifoxine hydrochloride has been used as a γ-aminobutyric acid (GABA)-receptor agonist to study its effects on insulin expression in α cell line (αTC1)

Biochem/physiol Actions

Etifoxine is an anxiolytic anticonvulsant, which promotes axonal regeneration. It binds to β2 and β3 subunits of the GABAA receptor complex, a different target site to benzodiazepines, and binds to the translocator protein (18 kDa) TSPO, formerly known as the peripheral or mitochondrial benzodiazepine receptor. TSPO carries cholesterol from the outer to the inner mitochondrial membrane, which is the rate-limiting step of steroidogenesis. Whereas, its anxiolytic effects involve GABAA receptors and TSPO, etifoxine′s neuroregenerative effects mainly involve TSPO.

The translocator protein (TSPO), once known as peripheral-type benzodiazepine receptor, was reported to be related with several physiological functions. Etifoxine is a clinically available anxiolytic drug, and has recently shown neuroprotective effects as a TSPO ligand. The aim of the

Type 1 diabetes is characterized by the destruction of pancreatic β cells, and generating new insulin-producing cells from other cell types is a major aim of regenerative medicine. One promising approach is transdifferentiation of developmentally related pancreatic cell types, including glucagon-producing
