  Targeting uncontrolled cell proliferation and resistance to DNA damaging chemotherapeutics with at least one reagent has significant potential in cancer treatment. Replication Protein A, the eukaryotic single-strand (ss) DNA binding protein, is essential for genomic maintenance and stability via roles in both DNA replication and repair. Reported herein are small molecules that inhibit the in vitro, in vivo, and cellular ssDNA binding activity of RPA, thereby disrupting the eukaryotic cell cycle, inducing cytotoxicity and increasing the efficacy of chemotherapeutic agents damage DNA, and/or disrupt its replication and/or function. These results provide new insights into the mechanism of RPA-ssDNA interactions in chromosome maintenance and stability. This represents a molecularly targeted eukaryotic DNA binding inhibitor and demonstrates the utility of targeting a protein-DNA interaction as a means of studying the cell cycle and providing a therapeutic strategy for cancer treatment.

  用至少一种试剂来靶向不受控制的细胞增殖和对 DNA 损伤性化疗药物的抗性，在癌症治疗中具有巨大的潜力。复制蛋白 A 是真核生物单链（ss）DNA 结合蛋白，通过在 DNA 复制和修复中发挥作用，对基因组的维护和稳定至关重要。本文报告的小分子能抑制 RPA 在体外、体内和细胞内的 ssDNA 结合活性，从而扰乱真核细胞周期，诱导细胞毒性，提高化疗药物对 DNA 的损伤和/或破坏其复制和/或功能的疗效。这些结果为研究 RPA-ssDNA 在染色体维护和稳定性中的相互作用机制提供了新的视角。这代表了一种分子靶向真核生物 DNA 结合抑制剂，证明了靶向蛋白质-DNA 相互作用是研究细胞周期的一种手段，并为癌症治疗提供了一种治疗策略。
