Wilforine

Customer Review

Based on 1 Customer Validation

Wilforine is an orally active JAK-STAT pathway inhibitor with immunomodulatory effects and the ability to inhibit osteoclast fusion. Wilforine disrupts lipid raft integrity, reprograms cholesterol and glycosphingolipid metabolic pathways, regulates NF-κB and the complement system, and modulates the expression of various interleukins. Wilforine also inhibits the Wnt11/β-catenin signaling pathway and suppresses the proliferation of fibroblast-like synoviocytes. Wilforine can serve as a quality and pharmacokinetic marker for Tripterygium glycoside tablets, and can be applied to research on related diseases such as rheumatoid arthritis, inflammatory osteolysis, and SAPHO syndrome.

In Vitro

Wilforine (100 μM; 6 days) inhibits osteoclast fusion in RAW264.7 cells by suppressing the JAK-STAT pathway, reducing expression of lipid raft scaffold proteins Stomatin and Flotillin-1, disrupting lipid raft integrity, and impairing localization and expression of fusion-related proteins CD9 and DC-STAMP^[1].
Wilforine (200-400 nM) dose-dependently inhibits the proliferation of collagen-induced arthritis fibroblast-like synoviocytes (CIA FLS)^[2].
Wilforine (30-300 μM; 20 h) induces significant cytotoxicity in human hepatoma HepG2 cells at concentrations of 30, 100, and 300 μM, with viability decreasing in a concentration-dependent manner^[3].

Decreased mRNA levels of MMP3 and fibronectin in joint synovium.
Alleviated synovial hyperplasia, pannus formation, and bone/cartilage damage.

Stock Solution Working Solution

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.

Protocol 1

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline

Solubility: ≥ 2.5 mg/mL (2.88 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.

Protocol 2

Add each solvent one by one: 10% DMSO 90% Corn Oil

Solubility: ≥ 2.5 mg/mL (2.88 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
