Effect of dl-praeruptorin A on ATP sensitive potassium channels in human cortical neurons



Effect of dl-praeruptorin A on ATP sensitive potassium channels in human cortical neurons



Acta Pharmacologica Sinica 22(9): 813-816



Objective: To investigate the effect of dl-praeruptorin A (Pd-Ia; a component of Baihua Qianhu (Peucedanum praeruptorum)) on ATP sensitive potassium channels (KATP channel) in human cortical neurons. Methodology: Standard whole cell recording method was used. Cell membranes were held at -40 mV, the commanding potential was -30 to +100 mV and duration was 600 ms. Results: Pd-Ia activated KATP channels in human cortical neurons in a concentration-dependent manner.
