BER-IN-1

BER-IN-1 is a base excision repair (BER) inhibitor that specifically targets DNA apurinic/apyrimidinic (abasic) sites. It works by disrupting the BER pathway through β-elimination and β,δ-elimination cleavage at these sites, leading to DNA double-strand breaks (DSBs). BER-IN-1 enhances the effects of the PARP inhibitor Olaparib in cancer cells with normal homologous recombination repair (HR) such as MDA-MB-231, HeLa, and SKOV3. When used in combination with Olaparib, BER-IN-1 can induce S-phase arrest and apoptosis. This compound is utilized in research on cancers, including breast, cervical, and ovarian cancers.
