TPE-2E N-oxide is a fluorescent probe used for hypoxia detection and tumor hypoxia imaging. Due to its active intramolecular motion, TPE-2E N-oxide shows no fluorescence in aqueous solution. In hypoxic environments, its N-oxide group undergoes two-electron reduction by CYP450 reductase and other heme protein reductases expressed under hypoxia, forming hydrophobic aggregates that trigger aggregation-induced emission through the restriction of intramolecular motion. TPE-2E N-oxide exhibits selective lipid droplet localization in cells. The absorption wavelength of TPE-2E N-oxide in dichloromethane is 313 nm; in a 99% hexane/dichloromethane mixed system, its excitation wavelength is 330 nm and emission wavelength is 460 nm. For in vitro cell imaging, excitation is performed at 405 nm, with an emission wavelength range of 430-560 nm .

SR-4554 is a probe for the measurement of tumor hypoxia. SR-4554 undergoes enzymatic single-electron reduction reactions within hypoxic cells. SR-4554 determines the 19F retention index for four commonly used mouse tumors (EMT6, SCCVII, KILT and RIF-I) through 19F MRS technique. SR-4554 can used to detect tumor Hypoxia noninvasively by 19F magnetic resonance spectroscopy ( 19F MRS) .
