The purpose of this study was to show basic
feasibility of non-invasively detecting small molecule thiols using
hyperpolarized [13C]cyanate. We detected rapid formation of the
expected hyperpolarized S-[13C]carbamyl thiol adduct after adding
cysteine to liquid hyperpolarized [13C]cyanate samples. This work
demonstrates a new non-enzymatic approach for detecting small molecule thiols
such as reduced glutathione, which could be very useful for research on
oxidative stress.
