Description
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).
in vitro
On the other hand, D-threo-1-phenyl-2-palmitoylamino-3-morpholino-1-propanol (PPMP), an inhibitor of glucosylceramide synthesis, blocked karyokinesis and reduced cyst production in culture. PPMP also altered the expression of cyst wall protein transcripts in encysting cells._x000D_
