DSP 4

DSP 4 Free base is a selective neurotoxin that targets noradrenergic neurons in the locus coeruleus noradrenergic system. DSP 4 Free base possesses the unique ability to cross the blood–brain barrier. DSP 4 Free base cyclizes to form a reactive aziridinium derivative that accumulates in noradrenergic neurons.

A poison.
