Potential Therapeutic Applications of Metal Compounds Directed Towards Hypoxic Tissues
Abstract:Medicinal Inorganic Chemistry offers the high diversity of metal coordination chemistry for the development of bioactive compounds for therapeutic or diagnostic medicinal purposes. The design of novel metal-based antitumor agents occupies a privileged position in this discovery process. On the other hand, the research on metal-based radiopharmaceuticals for therapy and imaging is a subarea of high priority and development. This review describes therapeutic applications of metal compounds directed towards hypoxic tissues. Strategies in the search for new bioreductive metal-based prodrugs will be discussed. In addition, approaches for the imaging of hypoxic tissues by using metal radionuclides will be exemplified.
