D-threo-PPMP also known as 1R,2R-(+)-1-phenyl-2-palmitoylamino-3-N-morpholine-1-propanol, is a bioactive sphingolipid. It plays a vital role in regulation of ceramide metabolism. D-threo-PPMP influences cytokinesis failure and glycosylation by inhibiting glucosyl ceramide synthase (GCS). D-threo-PPMP also stops acylation reaction by inhibiting the activity of 1-O-acylceramide synthase (1-O-ACS).
