Fig. 4. TP and ITP facilitate the oxidation of small molecules. (A) 1H NMR of TCEP (10 mM) incubated with ITP (1 mM) in 80% d6-acetone and 20% d6-DMSO. (B) Time course of oxidation of TCEP in the presence of TP or ITP. The fraction of oxidized TCEP was obtained by integration of the NMR signals. (C) Redox activity assay showing TP and ITP increase the rate of reduction of resazurin by TCEP.
