4. Conclusion
The ternary complexes REL3L0 (RE: Sm3+, Eu3+, Dy3+) were synthesis
and characterization. The result of agarose gel electrophoresis
suggested that the complex of SmL3L0 can cleave the plasmid
DNA at physiological pH and temperature. And it was found that
the process of pBR322 DNA cleavage was sensitive to pH, however,
these radical scavengers almost had no effect on the DNA cleavage
reaction. The antibacterial activities testing shows that all these
complexes exhibit excellent antibacterial ability against E. coli
and H. bacillus. The complexes belong to broad spectrum antibacterial
agents.
