cell line was the most sensitive to the presence of the obtained conjugates. The value of IC50 for oleic acid conjugate (4) was 7.7 μM, and it was 12 times lower than for CP alone (101.4 μM). The studied derivatives induced late apoptosis in all cancer cell lines, but not in normal cells. The most potent apoptosis inducer was conjugate 4, that resulted in the highest percentage of PC3 cells in late
