DSP-4 hydrochloride (Neurotoxin DSP 4 hydrochloride) is a highly selective neurotoxin and readily passes the blood-brain barrier with neurotoxic effects on noradrenergic neurons of adult and developing rats, can be used for the temporary selective degradation of the central and peripheral noradrenergic neurons, mainly those from the locus coeruleus (LC)[1][2].
