Enzyme Inhibitors for Glycolipids

Matreya offers inhibitors that will stop the enzymatic metabolism of glycolipids at various points in their biosynthetic routes. PDMP and PPMP are well known inhibitors of glucosylceramide synthase and both active and inactive isomers are available for comparison studies.1 Safingol is an important inhibitor of protein kinase C which controls the function of proteins through phosphorylation. Acid and alkaline ceramidase inhibitors, including NOE and D-MAPP, prevent the metabolism of ceramide to sphingosine.2 Conduritol B epoxide inhibits glucosidase activity and is commonly used to produce a model of Gaucher disease.3 A new class of inhibitors containing adamantane functional groups have opened up new routes of research into enzyme manipulation.4
