Sennoside B
Based on 3 publication(s) in Google Scholar
Sennoside B is a potent and orally active platelet-derived growth factor (PDGF) inhibitor. Sennoside B inhibits cell proliferation and the expression of phosphorylation of PDGFR-β, STAT-5, AKT and ERK induced by PDGF-BB. Sennoside B shows gastroprotective activities. Sennoside B has the potential for the research of gastritis.

Biological Activity
Sennoside B increases prostaglandin E2 (PGE2) levels and inhibits H+/K+-ATPase[1].
Sennoside B (50, 100 µM) increases the concentration of PGE2 to 105.4 pg/mL and 173.6 pg/mL in AGS gastric cells at doses of 50 μM and 100 μM, respectively[1].
Sennoside B (0, 10, 100, 1000 nM) decreases the expression of PDGF-BB-induced phosphorylation of PDGFR-β, STAT-5, AKT and ERK in a dose-dependent manner[2].

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
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: ≥ 2.5 mg/mL (2.90 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.
