A fluorescence sensor for nitroreductase detection in hypoxic cells and zebrafish

Results in Chemistry, 2021
Nitroreductase (NTR) is a type of cytoplasmic enzyme that depends on flavin mononucleotide or flavin adenine dinucleotide, and that is widely present in tumor cells where it increases during hypoxia. NTR can effectively reduce aromatic nitro compounds to
