  • Patent number: 10774063
    Abstract: 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.

  • Patent number: 9757350
    Abstract: Replication protein A (RPA) is a single-strand DNA-binding protein with essential roles in DNA replication, recombination and repair. Small molecule inhibitors (SMIs) with the ability to disrupt RPA binding activity to ssDNA have been identified and assessed using both lung and ovarian cancer cell lines. Lung cancer cell lines demonstrated increased apoptotic cell death following treatment with the SMI MCI13E, with IC50 values of ˜5 ?M. The A2780 ovarian cancer cell line and the p53-null lung cancer cell line HI 299 were particularly sensitive to MCI13E treatment with IC50 values below 3 ?M. Sequential treatment with MCI13E and cisplatin resulted in synergism, suggesting that decreasing RPA's DNA binding activity via a SMI may disrupt RPA's role in cell cycle regulation. Thus, RPA SMIs hold the potential to be used as single agent chemotherapeutics or in combination with current chemotherapeutic regimens to increase their efficacy.
