Apexbio Technology LLC Nortriptyline (hydrochloride) 894-71-3 100mg

Nortriptyline hydrochloride (CAS 894-71-3) is a dibenzocycloheptene-derived tricyclic antidepressant that inhibits monoamine reuptake transporters It selectively blocks the norepinephrine transporter (NET) with a Ki of 3 4 nM and inhibits the serotonin transporter (SERT) with a Ki of 161 nM thereby increasing synaptic concentrations of these neurotransmitters in the central nervous system In vitro nortriptyline dose-dependently suppresses spontaneous migration and chemotaxis of human polymorphonuclear cells In vivo studies in rodents indicate partial blockade of noradrenaline depletion in nerve terminals at higher doses Nortriptyline is frequently employed in research on monoaminergic neurotransmission and antidepressant pharmacology
