Oubain pump explained
Did you know?
Ouabain is a cardiac glycoside that acts by inhibiting the Na /K –ATPase sodium-potassium ion pump (but it is not selective). Once ouabain binds to this enzyme, the enzyme ceases to function, leading to an increase of intracellular sodium. This increase in intracellular sodium reduces the activity of the sodium … See more Ouabain /wɑːˈbɑːɪn/ or /ˈwɑːbeɪn, ˈwæ-/ (from Somali waabaayo, "arrow poison" through French ouabaïo) also known as g-strophanthin, is a plant derived toxic substance that was traditionally used as an See more Endogenous ouabain In 1991, a specific high affinity sodium pump inhibitor indistinguishable from ouabain was first discovered in the human circulation and … See more The total synthesis of ouabain was achieved in 2008 by Deslongchamps laboratory in Canada.
