Introduction

E7449 is an orally bioavailable, brain penetrable, small molecule dual inhibitor of PARP1/2 that also inhibits PARP5a/5b, otherwise known as tankyrase1 and 2 (TNKS1/2), important regulators of canonical Wnt/β-catenin signaling. It has IC50 values of 1.0 and 1.2 nM for PARP1 and 2, respectively.

E7449 inhibits PARP enzymatic activity and additionally traps PARP1 onto damaged DNA; a mechanism previously shown to augment cytotoxicity. E7449 inhibits Wnt/β-catenin signaling in colon cancer cell lines, likely through TNKS inhibition. E7449 stabilizes axin and TNKS proteins resulting in β-catenin de-stabilization and significantly alters expression of Wnt target genes. E7449 inhibits TNKS1 and 2 (PARP5a and 5b) with IC50 values of 50-100 nmol/L. Significant inhibitory activity is not observed for PARP3 or PARPs 6-16 (PARP9 and 13 lack activity and PARP4 had minimal signal).
