Pimobendan是一种磷酸二酯酶III(PDE III)选择性抑制剂,IC50为0.32 μM。
Information
Pimobendan (UD-CG 115 BS) is a selective inhibitor ofPDE3withIC50of 0.32 μM.
In vitro
Pimobendan exhibits selective inhibition of PDE III isolated from guinea pig cardiac muscle with IC50 of 0.32 uM compared to the inhibition of PDE I and PDE II (IC50s >30 μM). Pimobendan inhibits the activity of cAMP-PDE III with IC50 of 2.4 μM. It also exerts concentration-dependent positive inotropic effects in isolated guinea-pig papillary muscles with a potency (EC50) of 6.0 μM, which is partly due to selective cardiac PDE III inhibition. In human atrial cells, 100 μM pimobendan 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. In rabbit atrial cells, Pimobendan increases ICa(L) at +10 mV by 67.4.%, which is significantly lower than that obtained in human atrial cells
In vivo
Pimobendan shows a beneficial effect on survival in the murine model of EMC virus-induced myocarditis. Administration of Pimobendan significantly increases the final survival rate from 33.6% (control) to 53.3% (0.1 mg/kg) or 66.7% (1 mg/kg). Pimobendan (1 mg/kg) also significantly reduces myocardial cellular infiltration, the level of intracardiac tumor necrosis factor (TNF)-α and interleukin (IL)-1β compared with the control group, which shows no effect on myocardial necrosis, heart weight and body weight. Pimobendan suppresses expression of the intracardiac iNOS gene , causing reduction of intracardiac NO production.
