TNG348 is an orally bioavailable allosteric ингибитор targeting the ubiquitin-specific protease USP1. It selectively and potently blocks USP1 activity, preventing deubiquitination of proliferative PCNA and FANCD2, which disrupts DNA repair mechanisms. TNG348 demonstrates inhibitory effects against BRCA1/2-mutated and homologous recombination-deficient (HRD) breast and ovarian cancers .
