KF38789 inhibits P-selectin-induced superoxide production from human polymorphonuclear cells. Intravenously injected KF38789 significantly inhibits the thioglycollate (TG)-induced accumulation of leukocytes in the mouse peritoneal cavity[1].
KF38789 displays a concentration-dependent inhibition of U937 cell adhesion to immobilized P-selectin-Ig with an IC50 value of 1.97±0.74 μM[1].
KF38789 specifically inhibits P-selectin-dependent cell adhesion and the leukocyte recruitment in mouse peritonitis[1].
KF38789 (5 μM) significantly reduces closure of a 500-μm gap between confluent sheets of Human corneal epithelial (HCE)-T cells over an 8-hr period (by ～40%)[2].
Corneal epithelial cell migration is reduced in the presence of KF38789 (5 μM) [2].

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 (6.66 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (6.66 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 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
