Ouabain (10 –6 moles) and thevetin (10 –7 moles) completely inhibit the active transport of 3-methylglucose across the intestine of the frog in vitro. Acetylstrophanthidin has a weak inhibitory action. The results are discussed in view of a possible link between active ionic and sugar transport mechanisms.
