生物活性：
NSP-805 is a potent and selective inhibitor of guinea pig cardiac phosphodiesterase 3 (PDE3), and a cardiotonic agent with vasodilator properties.
体内研究：
In anesthetized dogs, intravenous (i.v.) injection of NSP-805 produces dose-dependent increases in left ventricular VVdp/dtmax and decreases in aortic blood pressure (ABP) with relatively small increases in heart rate (HR). The ED50 value for LVdP/dtmax of NSP-805 is 12 μg/kg. When the drugs is administered intraduodenally to anesthetized dogs, the ED50 value for LVdP/dtmax of NSP-805, is approximately 10 μg/kg. In the propranolol-induced heart failure model, NSP-805 completely improves the hemodynamic state of heart failure to normal levels. NSP-805(100 μg/kg) reduces systemic blood pressure significantly, but the increase of chorio-retinal blood flow is less than that at the low dose of NSP-805 (40 μg/kg) in rabbit eyes.
体外研究：
In isolated guinea pig left atria, NSP-805 shows positive inotropic EC50 value in order of potency of 0.18 μM. The in vitro positive inotropic effects of NSP-805 is accompanied by increases in tissue cyclic AMP and abolished by carbachol.
