Polyvalent inhibitory action of fusidic acid in isolated rat liver cells.
The steroidic antibiotic fusidic acid showed a polyvalent action on isolated rat liver cells. It displayed a strong inhibitory capability on protein synthesis in intact cells even stronger than that previously reported in cell-free extracts. Also, it inhibited basal gluconeogenesis and promoted an increase of the membrane permeability to trypan blue. However, the effects on both protein synthesis and basal gluconeogenesis were observed at doses smaller than those required to reduce the cell viability.
