Application

Strophanthidin was used to synthesize acetylstrophanthidin and the effect on neurotransmitter release from dog saphenous vein was studied.3

Biochem/physiol Actions

Strophanthidin is a cardiotonic steroid that elevates the activity of Na+/K+-ATPase in cardiac myocytes.1 It decreases the potassium content and raises the sodium content in rabbit renal cortex slices.2

1 The effect of alpha-adrenoceptor antagonists upon neurotransmitter release evoked by cardiac glycosides from sympathetic nerve terminals has been investigated in dog saphenous vein. 2 In rings of saphenous vein preloaded with [3H]-noradrenaline, acetylstrophanthidin (ACS) caused a concentration-dependent efflux of

Glycoside-induced cardiac inotropy has traditionally been attributed to direct Na(+)-K(+)-ATPase inhibition, causing increased intracellular [Na(+)] and consequent Ca(2+) gain via the Na(+)-Ca(2+) exchanger (NCX). However, recent studies suggested alternative mechanisms of glycoside-induced inotropy: (1) direct activation of sarcoplasmic reticulum Ca(2+)
