Descrizione

Descrizione generale

A 4′-chloro derivative of diazepam that lacks affinity for GABA-A receptors, but can serve as a ligand for the peripheral benzodiazepine receptor. Acts as an agonist for the 18 kDa translocator protein (TSPO) on the outer mitochondrial membrane (K_d = 4.4 nM). Diminishes the accumulation of β-amyloid peptides in the CA1 hippocampal region of gonadectomized (GDX) mice and in triple transgenic Alzheimer′s disease murine models (3xTgAD). However, it does not affect tau phosphorylation events as assessed by AT8 immunoreactivity. Also shown to reduce GFAP ionized calcium binding adaptor molecule-1 (IBA-1) in the 3xTgAD mice. Reported to increase testosterone and progesterone levels in GDX mice without affecting other steroid hormones. However, it does not have a significant effect on the levels of these hormones in aged 3xTgAD mice. In combination with another mitochondria targeting molecule, lonidamine, it is shown to induce apoptosis in MDA-MB-231 breast cancer cells.
