title: Effect of adriamycin and analogs on the nuclear fluorescence of propidium iodide-stained cells.
abstract: Adriamycin (ADR) and N-trifluoroacetyladriamycin-14-valerate, respectively, inhibit and enhance the nuclear fluorescence of cells stained with propidium iodide for DNA per cell estimation by flow cytometry. In cells incubated with ADR, the reduction in fluorescence is gradually manifested due to the slow intracellular drug transport. In contrast the effect of N-trifluoroacetyladriamycin-14-valerate on propidium iodide nuclear fluorescence is seen within 5 min of incubation. The effect of ADR on propidium iodide nuclear fluorescence could be detected in vivo even after 24 hr of ADR administration.
