CERAMIDE 3 DERIVATIVES BASED ON MONOUNSATURATED FATTY ACIDS

摘要

The present invention discloses ceramide 3 derivatives based on monounsaturated fatty acids. A preferred compound is N-oleoylphytosphingosine (Ceramide IIIB). A method for preparing these compounds is also disclosed. The solubility of these compounds is higher than the solubility of the corresponding saturated ceramide 3 derivatives, whereas their stability is comparable to saturated ceramide 3 stabilities. In addition, a method is described for maintaining the water permeability characteristics of the skin by topical application of a formulation containing a monounsaturated ceramide 3 derivative.
