title: Biological evaluation of a new C-xylopyranoside derivative (C-Xyloside) and its role in glycosaminoglycan biosynthesis.
abstract: The mechanical properties of skin are determined primarily by the extracellular matrix of the dermis. These mechanical and biological properties change significantly as a function of age. Key components of the extracellular matrix are proteoglycans, which are molecules composed of a core protein and covalently attached glycosaminoglycans. Proteoglycans and their constituent glycosaminoglycans are involved in many biological processes which are important for dermal function, such as proper formation of the collagen network. A recently developed compound, C-xylopyranoside derivative (C-Xyloside), was designed to mimic β-xylosides, which are known initiators of glycosaminoglycan biosynthesis. C-Xyloside was found, by several criteria, to act like β-xylosides, such as in the eliciting of an increase in glycosaminoglycan synthesis by human dermal fibroblasts in culture. This increase may lead to the preservation of matrix integrity and thereby contribute to the firmness of skin. Thus, C-Xyloside may be useful in improving the quality of skin.
