Effect of polyenic antibiotics on Ehrlich ascites and Novikoff hepatoma cells.

The incorporation of thymidine in Novikoff hepatoma cells and Ehrlich ascites cells was severely and irreversibly inhibited by the polyenic antibiotics filipin and lucensomycin, known for their action on phospholipid-cholesterol membranes. No inhibition could be shown on regenerating liver cells or on acellular preparations from tumor cells. Despite the… CONTINUE READING
