Soraprazan
Based on 2 publication(s) in Google Scholar
Soraprazan (BYK61359) is a selective, reversible K-competitive inhibitor of the H,K-ATPase (Ki=6.4 nM), with an IC50 of 0.19 μM in gastric glands. Soraprazan binds to the H,K-ATPase with a Kd of 28.27 nM. Soraprazan shows immediate inhibition of acid secretion and is more than 2000-fold selective for H,K-ATPase over Na,K- and Ca-ATPases.

Biological Activity
Soraprazan (BYK61359) is a potent inhibitor of gastric H,K-ATPase, with an IC50 of 0.1 μM when measured in ion-leaky vesicles in the presence of 1 mM potassium. Soraprazan (BYK61359) also effectively inhibits dibutyryl cAMP-stimulated [14C]AP accumulation in isolated gastric glands with an IC50 of 0.19 μM (0.09-0.40 μM geometric mean from n=6 with 95% confidence limits)[1].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 5 mg/mL (13.61 mM); Clear solution
This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.

Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
Protocol
[3H]Soraprazan binding studies are carried out at 20°C. In saturation experiments to determine the Kd value, ion-leaky gastric vesicles (0.01-0.02 mg/mL) are resuspended in a buffer composed of 20 mM Tris-HCl, pH 7.0, 2 mM MgCl2, and 2 mM ATP (pH 7.0 by Tris) in the presence of increasing concentrations of [3H]soraprazan (0.1 nM-1 μM). Nonspecific binding is determined in the presence of a 100 fold excess of unlabeled soraprazan over the concentration range of [3H]soraprazan used. The enzyme suspension (1 mL) is incubated at 20°C for 30 min and rapidly filtered through a nitrocellulose membrane filter (0.45 μM) prewet with a solution composed of 20 mM Tris-HCl, pH 7.0, 10% polyethylene glycol 3350 that is placed on top of a glass fiber filter. The membrane is ished five times with 2.5 mL of a buffer composed of 20 mM Tris-HCl, pH 7.0, and 10% polyethylene glycol 3350 to remove unbound inhibitor. The membrane is put into a 20-mL scintillation vial, dimethylacetamide (0.5 mL) is added to dissolve the membrane, and 14 mL of scintillation solvent is added and counted. Binding of [3H]soraprazan is determined by subtracting the nonspecific binding of [3H]soraprazan, obtained in the presence of the 100-fold excess of nonradioactive soraprazan, from the amounts of [3H]soraprazan bound to the membrane in the absence of the cold inhibitor.
