Fostriecin sodium salt
Potent inhibitor of protein phosphatase types 2A (PP2A) and 4 (PP4) with IC50 values of 1.5 nM and 3 nM respectively. Also exhibits weaker inhibition of topoisomerase II (IC50 = 40 μM) and protein phosphatase type 1 (PP1) (IC50 = 131 μM) with no apparent inhibition of protein phosphatase type 2B (PP2B). Active in vivo. Originally identified as an antitumor antibiotic from Streptomyces pulveraceous.

Preparing Stock Solutions
The following data is based on the product molecular weight 452.37. Batch specific molecular weights may vary from batch to batch due to solvent of hydration, which will affect the solvent volumes required to prepare stock solutions.
|Concentration / Solvent Volume / Mass||1 mg||5 mg||10 mg|
|1 mM||2.21 mL||11.05 mL||22.11 mL|
|5 mM||0.44 mL||2.21 mL||4.42 mL|
|10 mM||0.22 mL||1.11 mL||2.21 mL|
|50 mM||0.04 mL||0.22 mL||0.44 mL|
