A possible scheme for tenatoprazole metabolism in human liver microsomes. Notes were added to match the HPLC metabolites (Figure 2) with LC-QTOF metabolite (Figure S2). Nonenzymatic spontaneous desulfoxidation of 5′-OH tenatoprazole to 5′-OH tenatoprazole sulfide is possible but experimental evidence was not provided in this study.
