Biological Activity for SF 1670

SF 1670 is a PTPN2 and PTEN inhibitor (IC50values are 0.95 and 1.78 μM, respectively). Increases fMLP-elicited PIP3 signaling, Akt -phosphorylation and production of reactive oxygen species in neutrophils in vitro. Pretreatment of transfused neutrophils enhances chemotaxis to sites of bacterial infection and increases survival in neutropenic mice. Also inhibits CD45.
