C6 ceramide is a cell-permeable analog of naturally occurring ceramides. With a longer carbon chain than C2 ceramide, it is somewhat more hydrophobic, and may more closely mimic the effects of natural ceramides. [1] C6 ceramide mediates many diverse biological activities including apoptosis,[2] activation of protein phosphatase 2A, [1][3] and inhibition of the mitochondrial respiratory chain.[4] It also enhances the expression of COX-2 in rat granulosa cells [5] and stimulates the growth of bovine aortic smooth muscle cells. [6] C6 ceramide acts in neuronal axons to inhibit neurite growth. [7]
