Descripción

General description

A cell-permeable, potent, specific, and nontoxic inhibitor of the DNA repair enzyme, APE1 (human apurinic/apyrimidinic endonuclease; IC₅₀ = ~3 µM). Shown to target the APE1 active site and inhibit its 3′-phosphodiesterase and 3′-phosphatase activities. Exhibits minimal effects on endonuclease IV, BamH1 restriction endonuclease, or topoisomerase I even at concentration as high as 100 µM. Also shown to potentiate the cytotoxicity of several DNA damaging agents, such as MMS, temozolomide, Zeocin, and H₂O₂ in HeLa, HT1080, and MDA-MB-231 cells.
