Bis-pyrazolylpyridine complexes of some transition metal ions: Structure-Activity Relationships and Biological Activity

摘要

In this review we summarize our work on development of metallocomplexes with pincer type ligands such as bis-pyrazolylpyridine and its camphor derivatives. The review focuses on the correlation between the kinetics reactivity, DNA/protein interactions and cytotoxicity of these metallocomplexes. In order to establish the structure-activity relationship for the metal-based drugs, we have designed, synthesized and thoroughly studied the complexes with several transition metal ions: Pt(II), Pd(II), Au(III) and Rh(III). The first part of the present review is focused on the kinetic study of the ligand substitution reactions of complexes with small biomolecules (5'-GMP and some amino acids). The second part of the review is about DNA/BSA interactions of these complexes and last part is about cytotoxicity of Pt(II), Pd(II), Au(III) and Rh(III) complexes on different cell lines. Systematic summary of these results will contribute to the future development of transition metal ion complexes as potential antitumor agents and will have importance to understand the potential toxicity of metal-based drugs.
