DNA Repair

DNA repair inhibitors and activators act on enzymes that detect and fix damaged bases and broken strands. A 1993 review estimated that hydrolysis and oxidation damage thousands of DNA bases in every cell each day. In base excision repair, 8-oxoguanine DNA glycosylase 1 (OGG1) excises oxidized guanine, and apurinic/apyrimidinic endonuclease 1 (APE1) then cuts the abasic site. TH10785 is listed as an OGG1 activator, whereas APE1-IN-1 inhibits APE1. DNA repair protein RAD52 homolog (RAD52) became a target after a 2011 study found its loss lethal in cells lacking breast cancer susceptibility protein 2 (BRCA2). D-I03 inhibits RAD52, HAMNO blocks replication protein A (RPA), and CD00509 inhibits tyrosyl-DNA phosphodiesterase 1 (TDP1).

    UNC3474

    UNC3474 is a small molecule ligand that selectively binds to the aromatic methyl-lysine binding cage of 53BP1, exhibiting a dissociation constant (Kd) of 1.0 ± 0.3 μM. This binding inhibits the recruitment of 53BP1 to DNA double-strand breaks (DSBs) by stabilizing a pre-existing autoinhibited state of the protein within cells. UNC3474 is a valuable tool for researchers studying DNA damage response mechanisms and the regulation of genomic stability.

    D-G23

    D-G23 is a selective inhibitor of RAD52, which plays a critical role in DNA repair mechanisms. By disrupting RAD52-mediated pathways, D-G23 effectively suppresses the proliferation of BRCA1- and BRCA2-deficient cancer cells. This compound is particularly relevant for research involving homologous recombination-related cancers, including hereditary breast and ovarian cancers associated with BRCA1 and BRCA2 mutations.
