Application

Myriocin from Mycelia sterilia has been used as an inhibitor of sphingolipid or ceramide biosynthesis in various studies.

Biochem/physiol Actions

Myriocin from Mycelia sterilia is a fungal metabolite with potent immunosuppressant activity. It inhibits serine palmitoyltransferase at picomolar concentrations blocking synthesis of ceramide, a precursor of sphingomyelin and glycosphingolipids. It disrupts substratum adhesion of melanoma cells. It has been suggested that its immunosuppressant activity in the cytotoxic T-cell line CTTL-2 is due to apoptosis induction.
