Abstract
Effects of PF-10 the new fluorine-containing activator of ATP-dependent K-channels
were investigated on the guinea-pig isolated heart. PF-10 enchanced myocardial
contractility and decreased coronary vessels resistance in a dose-dependent manner.
Low doses (10 mM/L, 1 mM/L) of PF-10 attenuates of the spontaneous alterations
of heart rate, while high doses (0.1 mM/L) leds to these alterations. Previous
activation of ATP-dependent K-channels by PF-10 has a cardioprotective effect during
ischemia-reperfusion which a similar to the well-known phenomenon of ischemic
preconditioning.
