Description

General description

A tertiary N-alkylamine that acts as a pH dependent antagonist of GluN2B-NMDA receptors. Shown to be about 10-fold more potent in ischemic tissue (pH 6.9) than in normal healthy tissue (pH 7.6) (IC₅₀ = 190 nM and 1.8 µM, respectively). Effectively reduces the infarct volume in damaged brain tissue in a murine model of ischemic stroke (at 10 mg/kg, ED₅₀ ≤ 1 mg/kg) without impairing coordination or motor function. Also displays binding to hERG (IC₅₀ = 70 nM) and alpha1-adrenergic receptor (IC₅₀ = 4.9 µM).
