Zaprinast
Based on 3 publication(s) in Google Scholar
Zaprinast (M&B 22948) is a selective inhibitor of cGMP-selective Phosphodiesterase (PDE5). Zaprinast causes a significant increase in cGMP levels in myocytes. Zaprinast is a G protein-coupled receptor 35 (GPR35) agonist which activates rat GPR35 strongly and activates human GPR35 moderately. Zaprinast reduces vessel remodeling through antiproliferative and proapoptotic effects.

Zaprinast (0.1, 0.3, 1, 3, 10, 30 μM) induces intracellular calcium mobilization in the transfectant coexpressing FLAG-hGPR35 and the four exogenous Gα proteins in a concentration-dependent manner in HEK293 cells[2].
Zaprinast (100 μM; 5 min) can promote phosphorylation of five distinct amino acids in the C-terminal tail of human GPR35a in HEK293T cells[4].

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: ≥ 2.08 mg/mL (7.67 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
