Polygalaxanthone III
Based on 1 Customer Validation
Polygalaxanthone III is a representative xanthone component of Polygala tenuifolia. Polygalaxanthone III inhibits chlorzoxazone 6-hydroxylation catalyzed by CYP2E1, with an IC50 of 50.56 μM. Polygalaxanthone III repairs skin damage induced by M. furfur via activating STAT3 phosphorylation and exerts anti-inflammatory effects. Polygalaxanthone III can be used for research on M. furfur-related skin damage.

STAT3 |
CYP2E1 |
Polygalaxanthone III (0.5-2.0 mM; 24 h post-stimulation/6 h pre-incubation) significantly reduces lipid droplet formation in M. furfur-stimulated HaCaT cells, but shows no such effect when administered prior to stimulation[1].
Polygalaxanthone III (0.13-1.0 mM) exerts no significant inhibitory effect on the in vitro growth of M. furfur[1].

Animal Model:C57BL/6 (8-12 weeks old, 20 g, half male and half female, SPF grade, skin abrasion + topical Malassezia furfur suspension-induced injury)[1]
-
Dosage:1% (w/w); 2% (w/w)
-
Administration:topical; daily; 12 days
-
Result:Significantly promoted wound healing, reduced inflammatory cell infiltration, regularized collagen fiber arrangement, decreased lipid droplet formation in Malassezia furfur-stimulated HaCaT cells, and upregulated the phosphorylation of STAT3 to repair Malassezia-stimulated skin injury.

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 (3.66 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)
Solubility: ≥ 2.08 mg/mL (3.66 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 900 μL 20% SBE-β-CD in Saline, and mix evenly.
