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).

Accumulating studies have suggested that base excision repair (BER) is the major repair pathway of oxidative DNA damage in neurons, and neurons are deficient in other DNA repair pathways, including nucleotide excision repair and homologous recombination repair. However, some studies
