Solid-phase synthesis of a combinatorial library of dihydroceramide analogues and its activity in human alveolar epithelial cells

Add time:09/06/2019    Source:sciencedirect.com

Solid-phase synthesis of a small combinatorial library of dihydroceramide analogues as mixtures of erythro and threo diastereomers is described. Some dihydroceramide analogues cause growth arrest and apoptosis in a dose-dependent manner in human alveolar epithelial cells. This activity is likely due to the threo isomers, as evidenced by cellular studies with a pair of diastereomerically pure N-acyldihydrosphingosines. The apoptotic activity reported in this work provides information for the design of new compounds that may provide the basis for the generation of biochemical tools for the study of different pathologies where ceramide and/or dihydroceramide are involved.
