EAED inhibited high K+-induced tracheal ring contraction. a K+ (80 mM) induced a sustained contraction in mouse TR, which was blocked by EAED in a concentration-dependent manner. The dose-inhibition curve is presented. b Similar experiments were performed with vehicle (PSS containing 3% DMSO) as control. c The dose-inhibition curve is presented. The IC50 of EAED was 0.063 ± 0.005 mg/mL. The data were obtained from 7 TRs
