General description

A cell-permeable benzothiazolyltetrahydrothienopyridine compound that acts as a potent, competitive, and active site targeting inhibitor of APE1 (IC50 = 2.0 µM in a fluorescence based HTS assay; and 12 .0 µM in a radiotracer incision assay). Shown to block APE1 activity in HEK293T and HeLa cells extract (IC50 = 600 nM) and increase genomic AP site accumulation. Potentiates the cytotoxicity of DNA-damaging alkylating agents in HeLa cells by ~3-fold. Exhibits favorable pharmacokinetic properties and desirable ADME attributes. Due to its lipophilic nature, it crosses the blood-brain barrier rather easily and shows desirable stability (t1/2 = 80 min).

PARP2 is a DNA-dependent ADP-ribosyl transferase (ARTs) enzyme with Poly(ADP-ribosyl)ation activity that is triggered by DNA breaks. It plays a role in the Base Excision Repair pathway, where it has overlapping functions with PARP1. However, additional roles for PARP2 have
