Xylamine
Xylamine is a monoaminergic neurotoxin and benzylamine derivative that is closely related to DSP-4. It is a relatively selective noradrenergic neurotoxin, which is attributed to its high affinity for the norepinephrine transporter. DSP-4 is generally preferred over xylamine for use in scientific research and hence xylamine is limitedly employed. Xylamine was first described in 1975.
