Biological Activity

Description Tenatoprazole (TU-199,STU-Na) is a prodrug of the proton pump inhibitor (PPI) class, which inhibits proton transport with IC50 of 3.2 μM. Tenatoprazole labels only the gastric H(+),K(+)-ATPase alpha-subunit, approximately 2.6 nM/mg of tenatoprazole is bound to the H(+),K(+)-ATPase.
Targets
Proton pump [1] H(+),K(+)-ATPase [1]
(Cell-free assay)
3.2 μM
In vitro

Tenatoprazole labeled only the gastric H+,K+-ATPase alpha-subunit as has been found for other PPIs, approximately 2.6 nmol/mg of tenatoprazole is bound to the H+,K+-ATPase. The two enantiomers (R)- or (S)-tenatoprazole give the same stoichiometry of binding with 88% inhibition. Tenatoprazole labels only the peptide containing fifth and sixth transmembrane segments, these contain two cysteines, cysteine 813 in the luminal vestibule and cysteine 822 in the sixth transmembrane domain. [1]

In vivo

Tenatoprazole provides slow activation in vivo, which is predicted by its chemical activation rate in fasting rats. Tenatoprazole inhibits about 20–30% of enzyme activity even though acid secretion in fasting rats. (S)-tenatoprazole sodium salt hydrate provides a higher Cmax of 183 ng/mL, Tmax of 1.3 hours and AUC of 822 ng*h/mL in dog. [1]
