Research Abstract

The purpose of this project is to develop new MRI imaging probes that enable non-invasive visualization of hypoxic region in tumor. To this end, we tried to create hypoxia cleavable linker molecules by taking advantages of the redox activity and ligand exchanging property of a cobalt complex. Moreover, the hypoxia-selective linker was combined with a gadlinium complex or a fluorine-containing compound to achieve hypoxia-selective MRI contract agents.
