ly-139603

Atomoxetine hydrochloride (LY 139603) is the hydrochloride salt of atomoxetine, a phenoxy-3-propylamine derivative and selective non-stimulant, norepinephrine reuptake inhibitor with cognitive-enhancing activity. Although its precise mechanism of action is unknown, atomoxetine appears to selectively inhibit the pre-synaptic norepinephrine transporter, resulting in inhibition of the presynaptic reabsorption of norepinephrine and prolongation of norepinephrine activity in the synaptic cleft. The effect on cognitive brain function may result in improved attention and decreased impulsivity and activity levels.

(Rac)-Atomoxetine D7 hydrochloride is a deuterium labeled (Rac)-Atomoxetine hydrochloride. (Rac)-Atomoxetine hydrochloride is a racemic form of Atomoxetine hydrochloride.

Atomoxetine (HSDB 7352) is a selective norepinephrine inhibitor that may cause an increase in blood pressure by increasing norepinephrine concentrations in peripheral sympathetic neurons .Atomoxetine is a highly selective antagonist of presynaptic norepinephrine transporters with little or no affinity for other norepinephrine receptors or other neurotransmitter transporters or receptors, but has little or no affinity for 5- hydroxytryptamine transporter. Atomoxetine selectively inhibits reuptake of norepinephrine and can be used to treat adolescents with ADHD and chronic tics.

Atomoxetine-d3 hydrochloride, the deuterium-labeled form of Atomoxetine hydrochloride, acts as a potent and selective noradrenalin re-uptake inhibitor with Ki values of 5, 77, and 1451 nM for the inhibition of radioligand binding to human NET, SERT, and DAT, respectively [1] [2].
