Product Description

Overview

SM04554 is a small-molecule Wnt/β-catenin pathway activator renowned for its exceptional ability to activate hair follicle stem cells. Once in Phase III clinical trials, it is regarded as “the closest-to-market next-generation hair growth breakthrough.” By precisely upregulating Wnt signaling, it directly stimulates follicle stem cell proliferation and differentiation, inducing anagen entry and dramatically improving hair density and quality. Its core benefits include rapidly inducing new hair growth, substantially increasing hair count and thickness, reversing telogen follicle degradation, and offering excellent penetration and safety. Widely used in premium hair growth serums, ampoules, and professional scalp treatments.

Solubility in DMSO: 83.33 mg/mL (281.22 mM; solubilized with ultrasound; the solubility of the product is significantly affected by hygroscopic DMSO, so please use freshly opened DMSO)

Preparing Stock Solutions:

Please choose a suitable solvent to prepare the stock solution based on the product's solubility in different solvents. Once the solution is prepared, aliquot and store it to avoid product degradation caused by repeated freeze-thaw cycles.

Storage conditions and shelf life of the stock solution: -80°C for 2 years; -20°C for 1 year. When stored at -80°C, use within 2 years; when stored at -20°C, use within 1 year.


2.Animal Experiment

Please choose the appropriate dissolution method based on your experimental animals and administration route.

For the following dissolution schemes, please first prepare a clear stock solution according to the In Vitro method, then add solubilizers in sequence:  


—— To ensure the reliability of the experimental results, the clear stock solution can be appropriately stored based on storage conditions; for in vivo experimental working solutions, it is recommended to prepare them fresh and use them on the same day;  

The percentages shown before each solvent below refer to the volume proportion of that solvent in the final solution you are preparing; if precipitation or crystallization occurs during preparation, solubilization can be assisted by heating and/or ultrasonic treatment.


Protocol 1

Please add each solvent in order: 10% DMSO, 40% PEG300, 5% Tween-80, 45% Saline

Solubility: ≥ 2.08 mg/mL (7.02 mM); clear solution

This protocol can achieve a clear solution of ≥ 2.08 mg/mL (saturation unknown).

Using 1 mL of working solution as an example, take 100 μL of a 20.8 mg/mL clear DMSO stock solution and add it to 400 μL of PEG300, then mix well; next, add 50 μL of Tween-80 to the above mixture and mix thoroughly; then continue by adding 450 μL of saline and adjust the volume to 1 mL.

Preparation of saline: Dissolve 0.9 g of sodium chloride in ddH₂O and adjust the volume to 100 mL to obtain a clear, transparent saline solution.

Protocol 2

Please add each solvent in order: 10% DMSO, 90% (20% SBE-β-CD in saline)

Solubility: ≥ 2.08 mg/mL (7.02 mM); clear solution

This protocol can yield a clear solution with ≥ 2.08 mg/mL (saturation unknown).

For 1 mL of working solution, take 100 μL of 20.8 mg/mL clear DMSO stock solution and add it to 900 μL of 20% SBE-β-CD saline solution, then mix thoroughly.

Dissolve 2 g of SBE-β-CD (sulfobutyl ether β-cyclodextrin) powder in 10 mL of saline, fully dissolving to a clear and transparent solution.

Protocol 3

Please add each solvent in order: 10% DMSO, 90% Corn Oil

Solubility: ≥ 2.08 mg/mL (7.02 mM); clear solution

This method can obtain a clear solution with ≥ 2.08 mg/mL (saturation unknown). For animal experiments lasting more than half a month, use this method as appropriate.

For 1 mL of working solution, take 100 μL of 20.8 mg/mL clear DMSO stock solution and add it to 900 μL of corn oil, then mix thoroughly.
