(R)-Baclofen(STX209) is a selective GABAB receptor agonist[1].

IC50 & Target

GABAB receptor[1]

In Vivo

(R)-Baclofen (STX209) suppresses audiogenic seizures in the Fmr1-knockout mouse on the seizure-resistant C57BL/6 background with an effective dose of 1 mg/kg [5].
Acute intraperitoneal administration of (R)-Baclofen (STX209) significantly reduces the percent of mice displaying seizures (seizure incidence), with a minimum effective dose (MED) of 1.5 mg/kg[5].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
