Use of IQ-RIQ-R is a novel hypoxia-sensitive fluorescent probe, consisting of an indolequinone unit and a rhodol fluorophore.Target:IQ-R has good solubility in water and longer wavelength for absorption and emission, which are favorable for cellular bioimaging. While the fluorescence of rhodol in the IQ-R conjugate is quenched by the function of intramolecular indolequinone unit, it is restored under hypoxic conditions through the enzymatic one-electron reduction of IQ-R by NADPH: cytochrome P450 reductase to release the nonconjugated free rhodol. When administered to A549 cells, IQ-R is activated and reduced by endogenous reductase preferentially under hypoxic conditions, thereby visualizing hypoxic cancer cells by robust fluorescence. |
