Description

Fipamezole (MPV 1730; JP-1730) is a potent and orally active α2-adrenergic receptor antagonist with Ki values of 9.2 nM, 17 nM, and 55 nM for human α2A, α2B, and α2C, receptors, respectively. Fipamezole is an anti-dyskinetic agent, and can be used for the study of Parkinson's disease[1].

IC50 & Target[1]

human α2A-adrenoceptor

9.2 nM (Ki)

human α2B-adrenoceptor

17 nM (Ki)

human α2C-adrenoceptor

55 nM (Ki)

In Vitro

In functional assays, the potent antagonist properties of Fipamezole (JP-1730) are demonstrated by its ability to reduce adrenaline-induced 35S-GTPγS binding with KB values of 8.4 nM, 16 nM, 4.7 nM at human α2A, α2B, and α2C receptors, respectively. Fipamezole also has moderate affinity at histamine H1 and H3 receptors and the serotonin (5-HT) transporter (IC50 of 100 nM-1 μM)[1].

In Vivo

In the MPTP-lesioned marmoset, Fipamezole (1-10 mg/kg; po; once) significantly reduces L-dopa-induced dyskinesia without compromising the anti-parkinsonian action of L-DOPA (HY-N0304)[1].

Animal Model: Adult common marmosets (Callithrix jacchus, 300-345 g) injected with MPTP hydrochloride (2 mg/kg) and L-DOPA (8 mg/kg)[1]
Dosage: 1 mg/kg, 3 mg/kg, 10 mg/kg
Administration: po; once
Result: Significantly reduced L-DOPA-induced dyskinesia.

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.
