Fostriecin sodium salt from Streptomyces pulveraceus, >=98% (HPLC)

Not available outside of the UK & Ireland.

Application

Fostriecin has been used as a protein phosphatases type 2A (PP2A) inhibitor to study its effects on phosphorylated myosin light chain (pMLC) levels in axon initial segments (AIS). It has also been used as a PP2A inhibitor to study its effects on the regulation of protein kinase Akt (pAKT) by dopamine (DA) in larval zebrafish brain.

Biochem/physiol Actions

Fostriecin is a natural inhibitor of serine/ threonine phosphatases. It is a phosphate monoester produced by fermentation beer of Streptomyces pulveraceus. Fostriecin is a strong inhibitor of protein phosphatases type 2A and 4 (PP2A and PP4) and a weak inhibitor of protein phosphatases type 1 and 5 (PP1 and PP5). It exhibits anti-tumor activity against several tumor cells in vitro and L1210 and P388 leukemias in vivo. The anti-tumor activity of fostriecin is due to its ability to interfere with the reversiblephosphorylationof proteins that are involved in the progression of the cell cycle. It also exhibits cytotoxic effects. Fostriecin can inhibit the DNA, RNA and protein synthesis.
