Ceramide derivatives of the following general formula ##STR1## are described, wherein the individual radicals have the following meanings: X=--NH or --CH.sub.2, R.sub.1 =H or C.sub.1-11 -alkyl, R.sub.2 =C.sub.2-9 -alkenyl, wherein the double bond is in .alpha. position to the OR.sub.3 group R.sub.3 =H, C.sub.1-6 -alkyl or C.sub.1-6 -acyl and R.sub.4 =OH, C.sub.1-6 -alkoxy or morpholino. These ceramide derivatives represent inhibitors of the biosynthesis of sphingolipids.
