Biological Activity

Pimobendan (UD-CG115) is an oral Ca2+-sensitiser and PDE3 inhibitor (IC50=320 nM).
Pimobendan (UD-CG115) significantly increases the L-type calcium current (ICa(L)) (evoked by depolarization to +10 mV from a holding potential of -40 mV) by 250.4% with the half-maximal stimulation (EC50 ) of 1.13 μM.
Pimobendan (UD-CG115) increases ICa(L) at +10 mV by 67.4.%, which is significantly lower than that obtained in human atrial cells.
Pimobendan (UD-CG115) shows a beneficial effect on survival in the murine model of EMC virus-induced myocarditis.
