Perifosine (KRX-0401) is an oral-active, alkyl-phosphocholine Akt inhibitor with potential antineoplastic activity.

Akt:4.7 μM

Akt kinase assay: MM.1S cells are cultured in the presence or absence of perifosine (5 μM, 6 hours) and then stimulated with IL-6 (20 ng/mL, 10 minutes). In vitro akt kinase assay is then carried out using the Akt Kinase Assay Kit.

Cells are incubated in the medium with 10% FCS for 48 hours with indicated concentration of Periosine. Cell viability is determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. (Cell Proliferation Kit I; Roche). The absorbance at 590 nm is recorded using the 96-well plate reader.(Only for Reference)
