When the skin barrier is perturbed, there is a possibility of microbial infiltration and biochemical damage. Ceramides, as essential components of the skin lipid layer, help to maintain the barrier integrity. Decreased content of skin ceramides in epidermis is connected with skin diseases such as atopic dermatitis and psoriasis. Previous findings of our research group proved that a ceramide analogue with similar steric and hydrophobic parameters to skin ceramides could selectively supplement the recovery of perturbed human skin barrier. The goal of this study was to design a convenient synthesis of ceramide analogues derived from L-serine with two long aliphatic chains. The first chain is amidically bound lignoceric acid and the second chain is either a 10 or a 14 carbon polyfluorinated chain conjugated with the rest of the molecule by an ester bond. Furthermore, the aim of this...
