Guanabenz acetate (GBA) is a derivative of guanabenz, an alkaloid found in the bark of the guanabana tree. It is an alpha2A-AR adrenergic agonist and IGRS (imidazoline I2 binding site) selective ligand. It is also an activator of alpha2B-AR (alpha2b-adrenergic receptor) and alpha2C-AR (alpha2c-adrenergic receptor). Guanabenz acetate inhibits the release of norepinephrine, a neurotransmitter involved in the regulation of blood pressure. It may act to have antioxidant, anti-inflammatory, and antinociceptive activity in vitro.
