Fig. 2 The reversible reaction of HDSF in hypoxia-reoxygenation cycle.

ESI-MS spectra of probe solutions (20 μM in PBS buffer) incubated with RLM (250 μg mL⁻¹) and NADPH (100 μM), a HDSF incubated in hypoxic condition. The supernatant of the reaction solution was directly used for detection. b HDSF solution exposed in the air after incubated in the hypoxic environment. c HDMA incubated in hypoxic condition. Solutions of (b) and (c) were quenched with MeCN, then vortexed and centrifuged, and the organic layers were used for detection respectively.
