L-threo-PPMP is a GlcT (UDP-Glc: Ceramide β1,1glucosyltransferase) inhibitor. L-threo-PPMP inhibits glycosphingolipid biosynthesis and induces apoptosis. L-threo-PPMP has anti-cancer activity[1].

ChEBI: (1S,2S)-1-phenyl-2-palmitoylamino-3-morpholino-1-propanol is an N-[1-hydroxy-3-(morpholin-4-yl)-1-phenylpropan-2-yl]hexadecanamide in which both stereocentres have S configuration. It is an enantiomer of a (1R,2R)-1-phenyl-2-palmitoylamino-3-morpholino-1-propanol.
