Abstract
Interactions between cyclosporin A and three silymarin flavonoids (silybin, silydianin, and silychristin) were studied on the rat hepatocyte plasma membrane using the replacement of [3H]cyclosporin A by silymarin flavonoids. It was found that flavonoids significantly replaced CsA from its binding to the rat hepatocyte plasma membrane. It seems that these two types of compounds are competitors at the same binding site of the plasma membrane receptor.
