Abstract:
Objective:To investigate the effects of daurinsoline (DS) on L-type calcium channel Cav1.2 expressed in HEK293 cells.Methods:Cav1.2 was transferred into HEK293 cells using Lipofectamine 2000, and the effects of DS on Cav1.2 currents (ICav1.2) were analyzed by whole-cell patch clamp techniques. Results:DS at 1,3 and 10 μmol·L-1could inhibit the ICav1.2in HEK293 cells in a dose-dependent manner. The inhibitory rate was(14.68 ± 4.02) %,(32.37 ± 6.63) % and(59.63 ± 5.23) %,respectively. The inhibitory rate of DS at 3 μmol·L-1was 40 % of that of 3 μmol·L-1isradipine(a L-type calcium channel blocker). Conclusion:DS can inhibit the ICav1.2in HEK293 cells in a dose-dependent manner and the inhibition of DS is weaker than that of isradipine.
