l-threo-ppmp

L-threo-PPMP is an inhibitor of GlcT, which is the UDP-Glc: Ceramide β1,1glucosyltransferase enzyme. It effectively inhibits glycosphingolipid biosynthesis, while also inducing apoptosis. These properties of L-threo-PPMP contribute to its notable anti-cancer activity.

DL-threo-PPMP is an inhibitor of sphingosine synthetase (sphingosine synthetase) in Plasmodium falciparum. It inhibits the enzymes activity by binding to it, mimicking the substrate of sphingosine. This inhibition results in a rapid decline in the activity of sensitive sphingosine synthetase, selectively disrupting the interconnected tubular network in the cytoplasm of the host cell at the TVM. This action also blocks the proliferation of the Plasmodium falciparum. DL-threo-PPMP is valuable in studies of Plasmodium falciparum biology and the development of new anti-malarial strategies.

D-threo-PPMP is a glucosylceramide (GlyCer) synthetase inhibitor.1,2It is the active enanantiomer and enzymatic inhibitory component of the racemic DL-threo-PPMP . In MDCK kidney epithelial cells, D-threo-PPMP induces a 70% reduction in cell growthin vitroat 20 μM and significantly inhibits DNA synthesis at 3 μM.3[Matreya, LLC.
