Pro-xylane
Based on 1 Customer Validation
Pro-xylane (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. 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. Pro-xylane can effectively promote the synthesis of collagen fibers and hyaluronic acid in the dermis. Pro-xylane is used in the field of anti-aging cosmetics to improve skin hydration and elasticity. Pro-xylane is eco-friendly and biodegradable.

Biological Activity
Pro-xylane (0.3-3.0 mM; 96 h) stimulates the synthesis of GAGs in human fibroblasts[1].
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, Pro-xylane produces >99% β,S-diastereomeric excess[2].
Pro-xylane has the ability of efficient asymmetric synthesis[3].
