DPI 201-106

Research use only, not for human use.

DPI 201-106 is a cardioselective inhibitor of the TTX-resistant h1 Na channel inactivation resulting in a positive inotropic effect.

DPI 201-106 is a cardioselective inhibitor of the TTX-resistant h1 Na channel inactivation resulting in a positive inotropic effect. DPI-201-106 also inhibits the inward and delayed rectifier potassium currents and L-type calcium current.(In Vitro):DPI 201-106(0.1 - 3 μM) 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. DPI 201-106 increases the Ca2+ sensitivity(EC50 = 0.2 nM) of skinned fibres from porcine trabecula septomarginalis.(In Vivo):DPI 201-106(0.2 mg/kg i.v) administration increased left ventricular dP/dtmax in anesthetized dogs.

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.

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. .
