【Abstract】 It is shown with 21P nuclear magnetic resonance that cytochrome c can induce hexagonol Ⅱ phase transition on multilayer vesicle membrane which consists of cardiolipin and dipalmitoyl-phosphatidyl-chotin. Adriamycin can inhibit the polymorphic transition induced by cytochrome c, indicating that this aniitumor drug has the ability to stabilize the bilayer of the membrane studied. The mechanisms for polymorphic transition and inhibition effect of adriamycin on mitochondia are discussed in terms of lipid-protein interaction.更多还原
