Synthesis and study of ceramides with deuterated acyl chain
Hudská, Klára ; Vávrová, Kateřina (advisor) ; Nováková, Veronika (referee)
Charles University in Prague Faculty of Pharmacy in Hradec Králové Department of Inorganic and Organic Chemistry Candidate: Klára Hudská Supervisor: Doc. PharmDr. Kateřina Vávrová, Ph.D. Title of Diploma Thesis: Synthesis and study of ceramides with deuterated acyl chain Ceramides are a complex group of lipids belonging to sphingolipids. They are the most important component in stratum corneum and play an essential role in protecting the skin from excessive water loss and other environmental damages. Despite the fact that ceramides are a subject of intensive research, the exact effect of their structure on barrier skin function has not been fully explained. The aim of this diploma thesis was to synthesize a series of ceramides derived from sphingosin with deuterated acyl chains with chain lenght 4C, 16C and 24C and their study using Fourier transform infrared spectroscopy to understand the behaviour of ceramides in SC and their structure-activity relationships. The study of the synthesized ceramides using ATR-FTIR spectroscopy revealed that, at skin temperature, lipid chains are arranged in orthorhombic subcell, mostly with all-trans conformation. While the CerNS24 prefers extended conformation with its acyl associated with the acyl of LA and cholesterol associated with the sphingosin chain in...
