A comparative analysis of the time-dependent antiproliferativeeffects of daunorubicin and WP631Silvia Villamarı´n1,*, Sylvia Mansilla1,*, Neus Ferrer-Miralles1, Waldemar Priebe2and ... drugaccumulated in the cells. Despite the slow uptake rate, the antiproliferative capacity of WP631 (measured as IC50after a 72-h continuous treatment) was greater than that of daunorubicin. The propensities ... preparation was examined. A cellgallery was created by relocation of cells from each of the major peaks in the histogram of integrated red fluorescence. The presence of polyploid cells was determined...
