Abstract: Four transition metal(II) complexes with podophyllic acid hydrazide (HL) were prepared and characterized by elemental analysis,
complexometric titration, thermal analysis, conductivity, IR, and 1H NMR. The complexes have the general formula ML2 · nH2O, where M = Zn, Cu, Co, and Ni, n = 2 or 0. Anti-tumor activities of podophyllotoxin, HL, ZnL2 · 2H2O, and NiL2 were tested by both the MTT and the SRB method. The results show that the activities of the complexes against the tumor cells
tested are superior to HL and the anti-tumor activity of NiL2 is even similar to that of podophyllotoxin.
Keywords: transition metal - complexes - podophyllic acid hydrazide - anti-tumor activities
