| Outline of Final Research Achievements |
New tetrazolato-bridged dinuclear platinum(II) complexes were designed and synthesized to combine with DDS carrier or to introduce halogen into the complexes. Our in vivo study using mice with a subcutaneous homograft of Colon-26 colorectal cancer cells indicates that the tetrazolato-bridged dinuclear platinum(II) complexes are promising next-generation platinum-based drug candidates with markedly high and long-lasting antitumor efficacy. Indeed, the tumour growth in mice treated with the lead compound was much slower than that in mice treated with platinum-based drug oxaliplatin, which is used for the treatment of colorectal cancer. Even more remarkable, the lead compound exhibited high tumor-reduction effects against large-sized tumours, which sustained for a few weeks after a single intravenous dose of the compound.
