A series of prodrugs for nitroreductase (NTR) based 4-β-amino-4′- Demethylepipodophyllotoxin as potential anticancer agents were synthesized, and their antiproliferative activities in vitro showed compounds 2b (IC50 = 0.77, 0.83 and 1.19 μM) and 2d (IC50 = 0.98, 0.91 and 1.58 μM) were greatly selectively toxic to tumor cells A-549, HeLa and HepG2, respectively, and lower damage to normal WI-38 cells
