Description

Lusaperidone (R107474) is an α2 adrenergic receptor antagonist with Kis of 0.13 and 0.15 nM for α2A and α2C, respectively.

IC50 & Target

Ki: 0.13 nM (α2A adrenergic receptor), 0.15 nM (α2C adrenergic receptor)[1]
In Vitro

Lusaperidone has subnanomolar affinity for α2A and α2C adrenergic receptor (Ki=0.13 and 0.15 nM, respectively) and shows nanomolar affinity for the hα2B adrenergic receptor and h5-HT7 receptors (Ki=1 and 5 nM, respectively). Lusaperidone interacts weakly (Ki values ranging between 81 and 920 nM) with dopamine-hD2L, -hD3 and -hD4, h5-HT1D-, h5-HT1F-, h5-HT2A-, h5-HT2C-, and h5-HT5A receptors. Lusaperidone, tested up to 10 μM, interacts only at micromolar concentrations or not at all with any of the other receptor or transporter binding sites tested in this study. Lusaperidone has been shown to reverse the clonidine-induced inhibition of cyclic AMP production mediated by human α2A and α2C adrenoceptors expressed in cell lines (Kb is 2.8 and 4.4 nM, respectively) and is a full antagonist on both receptor subtypes[1].

In Vivo

Lusaperidone occupies the α2A and α2C adrenergic receptor with an ED50 of 0.014 mg/kg sc (0.009-0.019) and 0.026 mg/kg sc (0.022-0.030), respectively. The uptake of R107474 after in vivo intravenous administration is very rapid; in most tissues (including the brain) it reaches maximum concentration at 5 min after tracer injection[1].

Animal Administration
[1]

Rats: Radio labeled Lusaperidone (24–28 GBq/μmol) is injected into the tail vein of diethyl ether anesthetized male Wistar rats (200–250 g). The rats received 30–40 MBq (injected at the start of the experiment) in 300 μL saline including 10% (v/v) ethanol. The rats are sacrificed by cervical dislocation at 5, 10, 20, and 30 min post injection under diethyl ether anesthesia. A blood sample is taken by cardiac puncture and selected tissues are rapidly dissected and weighed. The radioactivity is measured[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
