(S)-Pro-xylane
Based on 1 Customer Validation
(S)-Pro-xylane ((S)-Hydroxypropyl tetrahydropyrantriol) is a bioactive C-glycoside that targets the biosynthesis pathway of glycosaminoglycans/mucopolysaccharides (GAGs) in the skin matrix and can be absorbed transdermally. (S)-Pro-xylane stimulates the biosynthesis of GAGs in fibroblasts, enhances the structural stability of the skin extracellular matrix, improves skin elasticity and moisturizing ability, and delays wrinkle formation. (S)-Pro-xylane can effectively promote the synthesis of collagen fibers and hyaluronic acid in the dermis. (S)-Pro-xylane is used in the field of anti-aging cosmetics to improve skin hydration and elasticity. (S)-Pro-xylane is eco-friendly and biodegradable.

Biological Activity
(S)-Pro-xylane (0.3-3.0 mM; 96 h) stimulates the synthesis of GAGs in human fibroblasts[1].
(S)-Pro-xylane is the catalytic substrate of the recombinant carbonyl reductase R129E/D210F, whose key activity lies in the high stereoselectivity of the β-S configuration. Under the catalysis of R129E/D210F, (S)-Pro-xylane produces >99% β,S-diastereomeric excess[2].
(S)-Pro-xylane has the ability of efficient asymmetric synthesis[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 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.08 mg/mL (10.82 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 (10.82 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.
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.
For the following dissolution methods, please prepare the working solution directly:
It is recommended to prepare fresh solutions and use them promptly within a short period of time.
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.
