Information
E7449 is an orally bioavailable, brain penetrable, small molecule dual inhibitor ofPARP1/2and 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.
Targets
PARP1 ; PARP2 1 nM; 1.2 nM
In vitro
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).
In vivo
Chemotherapy is potentiated by E7449 and single agent has significant antitumor activity in BRCA-deficient xenografts. E7449 lacks single agent antitumor activity in vivo. E7449 antitumor activity is increased through combination with MEK inhibition. Treatment with E7449 at 30 or 100 mg/kg in xenografts is well-tolerated without any significant body weight loss or deaths. Treatment with E7449 at 100 mg/kg resulted in significant PARP inhibition that is sustained for at least 12 hours and recovered to basal levels within 24 h.
