Functions

Myriocin is a fungal metabolite with potent immunosuppressant activity. It inhibits serine palmitoyltransferase (Ki = 0.28 nM) blocking the synthesis of ceramide. It was found to suppress melanoma cell proliferation by cell cycle arrest at the G 2/M phase through decreased sphingolipid levels and increased p53 and p21 (waf1/cip1) expression.

Application Procedures

First dissolved in DMSO (up to 20 mg/ml), then diluted to aqueous buffer. Solutions in DMSO may be stored at -20° for up to 4 months.
