AZ9482 is a poly(ADP-ribose) polymerase (PARP) inhibitor (IC50s = 1, 1, 46, 640, 9, and 160 nM for PARP1, -2, -3, -6, TNKS1/PARP5a, and TNKS2, respectively).1 It induces centrosome declustering (EC50 = <18 nM) and a multipolar spindle phenotype in HeLa cells. AZ9482 inhibits the growth of OCI-LY19 diffuse large B cell lymphoma (DLBCL) cells (GI50 = 3 nM).
