(RS)-Salsolinol hydrobromide is the hydrobromide form of (±)-Salsolinol. (RS)-Salsolinol hydrobromide is a Dopamine -derived endogenous metabolite. (RS)-Salsolinol hydrobromide activates μ-opioid receptors (MORs), reduces GABAergic transmission, increases the excitability of dopamine (DA) neurons, and thus accelerates the sustained firing of neurons in the posterior ventral tegmental area (pVTA).
