bi 2536

BI2536 is an effective Plk1 inhibitor (IC50: 0.83 nM). It has 4- and 11-fold greater selectivity than Plk2 and Plk3.

PLK1 BRD4-IN-2 (compound 15), an analog of BI-2536, simultaneously inhibits both Polo-like kinase 1 (PLK1 IC 50 = 40 nM) and BRD4 bromodomain (BRD4-BD1 IC 50 = 28 nM) as a dual inhibitor [1].

BI-4834 is a potent and selective Polo-like kinase 1 (PLK1) inhibitor. BI-4834 is also analogue (or Me-Too) of BI-2536. In vitro test shows that BI 4834 inhibits PLK1 with IC50=7.6 nm, but with higher selectivity over the related enzyme PLK3 (IC50 198.4 nm) as BI-2536.
