ASP0819 is a potent, selective and orally active intermediate conductance channel KCa3.1 (IK1) opener with EC50 and Emax values of 102.4 nM and 99.0%, and 392.9 nM and 102.4% in human and rat KCa3.1-expressing cells, respectively.
ASP0819 does not show show more than 50% activity in the rKCa2.2 assay, hKCa1.1 assay, and L-type Ca2+ channel assay.
ASP0819 at doses of 0.1, 0.3, and 1 mg·kg−1 significantly recovered the decrease in muscle pressure threshold in rat fibromyalgia models of reserpine-induced myalgia (RIM) and vagotomy-induced myalgia (VIM).
ASP0819 significantly reduced both the spontaneous activity and mechanically evoked responses in Aδ-fibers in the rat RIM model.
ASP0819 significantly reduced the number of abdominal contractions as an indicator of abdominal pain behaviors in the rat visceral extension model and withdrawal responses in the osteoarthritis model, respectively.
