生物活性:
DPI 201-106 (SDZ 201106) is a cardiotonic agent with a synergistic sarcolemmal and intracellular mechanism of action. DPI 201-106 shows cardioselective modulation of voltage-gated sodium channels (VGSCs) resulting in a positive inotropic effect.
体内研究:
In anesthetized dogs, left ventricular dP/dtmax is increased by DPI 201-106 0.2 mg/kg i.v.In digoxin-pretreated anesthetized cats, DPI 201-106 is infused up to an accumulated dose of 12.22 mg/kg i.v. .
体外研究:
DPI 201-106 increases the Ca2+-sensitivity of skinned fibres from porcine trabecula septomarginalis with an EC50 of 0.2 nM.DPI 201-106 produces concentration-dependent positive inotropic effects in guinea-pig and rat left atria, kitten, rabbit and guinea-pig papillary muscles and Langendorff perfused hearts of rabbits between 0.1 and 3 μM.
