Application
SCH-28080 was used to treat zebrafish embryos to study the role of H+/K+-ATPase in establishment of left-right axis during development.
Biochem/physiol Actions
SCH-28080 is a potent inhibitor of gastric H+ and K+-ATPase. The novel antiulcer agents, SCH-28080 and SCH-32651 were examined for their ability to inhibit the H+K+ ATPase enzyme activity in a preparation of microsomal membranes from rabbit fundic mucosa. SCH- 28080 inhibited the isolated enzyme activity with a potency similar to omeprazole, IC50s of 2.5 and 4.0 μM respectively. SCH 32651 was less potent exhibiting an IC50 of 200.0 μM. Both compounds may therefore exert their antisecretory activity via a direct inhibition of the parietal cell H+K+ ATPase.

The H,K-ATPase, consisting of α and ß subunits, belongs to the P-type ATPase family. There are two isoforms of the α subunit, HKα₁ and HKα₂ encoded by different genes. The ouabain-resistant gastric HKα₁-H,K-ATPase is Sch28080-sensitive. However, the colonic HKα₂-H,K-ATPase from

The degree of conservation among phyla of early mechanisms that pattern the left-right (LR) axis is poorly understood. Larvae of sea urchins exhibit consistently oriented LR asymmetry. The main part of the adult rudiment is formed from the left coelomic

Proton pump inhibitors (PPIs) are widely used in the treatment of acid-related diseases. However, several unmet medical needs, such as suppression of night-time acid secretion and rapid symptom relief, remain. In this study, we investigated the pharmacological effects of 1-[5-(2-fluorophenyl)-1-(pyridin-3-ylsulfonyl)-1H-pyrrol-3-yl]-N-methylmethanamine

The primary sequence of non-gastric H,K-ATPase differs much more between species than that of Na,K-ATPase or gastric H,K-ATPase. To investigate whether this causes species-dependent differences in enzymatic properties, we co-expressed the catalytic subunit of human non-gastric H,K-ATPase in Sf9 cells
