title: [Mechanism of Na,K-ATPase inhibition with gossypol and megasin].
abstract: Kinetic patterns of megosin and gossypol effects on properties of highly purified Na+, K+-ATPase were studied. Inhibition of the enzymatic activity appears to occur due to interaction of these compounds with the enzyme probound to the intracellular side of the transport enzyme.
