Hibifolin
Based on 1 Customer Validation
Hibifolin is a flavonol glycoside that can be isolated from Helicteres isora. Hibifolin is an inhibitor of adenosine deaminase (ADA) (Ki = 49.92 μM). Hibifolin protects neurons against β-amyloid-induced neurotoxicity. Hibifolin possesses a potent protective activity against cell death induced by aggregated Aβ. Hibifolin can abolish Aβ-induced caspase-3 and caspase-7 activation. Hibifolin induces Akt phosphorylation in cortical neurons. Hibifolin is also a natural sortase A (SrtA) inhibitor (IC50 = 31.2 μM) through direct binding to SrtA protein. Hibifolin attenuates the pathogenic behavior of Staphylococcus aureus including adhesion, invasion, and biofilm formation. Hibifolin improves the survival of pneumonia induced by Staphylococcus aureus in mouse model and alleviates pathological damage. Hibifolin shows a synergistic antibacterial effect with Cefotaxime (HY-A0088A).

生物活性
Ki: 49.92 μM (ADA)[1]
Hibifolin (100 μM) shows about 60% inhibition of the ADA (10 μM) enzymatic activity[1].
Hibifolin (0.5-50 μM, 24 h) reduces the release of LDH induced by Aβ in cortical neurons[2].
Hibifolin (50 μM, 0-120 sec) reduces the amount of Aβ-induced Ca2+ by 70% in cortical neurons[2].
Hibifolin (50 μM) induces the phosphorylation of Akt to approximately 2-fold[2].
Hibifolin (0-1000 μg/mL) remarkably inhibits the activity of SrtA with an IC50 of 31.2 μM[3].
Hibifolin (32-256 μg/mL) decreases the adhesion of S. fibrinogen to fribinogen with the concentration of 256 μg/mL and significantly inhibits bacterial invasion of A549 cells[3].

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 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (5.06 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.
