NSC15520 

NSC15520 is a small molecular inhibitor of Replication Protein A (RPA). NSC15520 specifically recognizes the RPA N-terminal DNA binding domain (DBD), and blocks the interaction of RPA with p53 or RAD9. NSC15520 also inhibtis helix destabilization of a duplex DNA (dsDNA) oligonucleotide, involves in DNA replication, DNA repair, DNA recombination, and DNA damage response signaling^[1].

NSC15520 (10-.5-10-3.5 M) inhibits the interaction of RPA with GST-p53 peptide with an IC₅₀ value of 10 μM^[1].
NSC15520 (0-400 μM; 5 min) inhibits helix destabilization activity^[1].
NSC15520 (0-400 μM; 5 min) inhibits RPA binding of a dsDNA 30-mer^[1].
