Technical Data
Myriocin (Thermozymocidin, ISP)
Biochemicals Storage: -20CShipping: Blue Ice
Myriocin is an a-amino fatty acid derived from species of several genera of fungi, notably Myriococcum, Melanconis and Isaria. Myriocin is a potent inhibitor of sphingosine biosynthesis by blocking the first enzyme in the pathway, serine palmitoyltransferase. Myriocin induces apoptosis by depletion of cellular sphingolipids, inhibits proliferation of IL-2-dependent mouse cytotoxic cells and is a potent immunosuppressant.
