    Biological Activity

    Pomstafib-2 is the pivaloyloxymethyl ester prodrug of Stafib-2, which is a potent, selective STAT5b inhibitor with Ki of 9 nM.
    Pomstafib-2 decreases the phosphorylation at STAT5b Tyr699 with IC50 of 1.5 uM in STAT5b-GFP-transfected K562 cells in human leukaemia cells and induces apoptosis in a STAT5-dependent manner.
    Pomstafib-2 shows high selectivity for STAT5b over STAT5a.
