C8 Dihydroceramide acts as a negative control for C8 Ceramide, a cell-permeable analog of natural ceramides. C8 Ceramide, also known as N-Octanoyl-D-erythro-sphingosine, exhibits potent chemotherapeutic properties and anti-proliferation effects. Additionally, it stimulates dendritic cells to enhance T cell responses during viral infections. In vitro studies have also shown that C8 Ceramide induces a slight activation of protein kinase (PKC) (4).
