  A site-selective, irreversible inhibitor of the DNA replication auxiliary factor proliferating cell nuclear antigen (PCNA)

  摘要：

  Proliferating cell nuclear antigen (PCNA) assumes an indispensable role in supporting cellular DNA replication and repair by organizing numerous protein components of these pathways via a common PCNA-interacting sequence motif called a PIP-box. Given the multifunctional nature of PCNA, the selective inhibition of PIP-box-mediated interactions may represent a new strategy for the chemosensitization of cancer cells to existing DNA-directed therapies; however, promiscuous blockage of these interactions may also be universally deleterious. To address these possibilities, we utilized a chemical strategy to irreversibly block PIP-box-mediated interactions. Initially, we identified and validated PCNA methionine 40 (M40) and histidine 44 (H44) as essential residues for PCNA/PIP-box interactions in general and, more specifically, for efficient PCNA loading onto chromatin within cells. Next, we created a novel small molecule incorporating an electrophilic di-chloro platinum moiety that preferentially alkylated M40 and H44 residues. The compound, designated T2Pt, covalently cross-linked wild-type but not M40A/H44A PCNA, irreversibly inhibited PCNA/PIP-box interactions, and mildly alkylated plasmid DNA in vitro. In cells, T2Pt persistently induced cell cycle arrest, activated ATR-Chk1 signaling and modestly induced DNA strand breaks, features typical of cellular replication stress. Despite sustained activation of the replication stress response by the compound and its modestly genotoxic nature, T2Pt demonstrated little activity in clonogenic survival assays as a single agent, yet sensitized cells to cisplatin. The discovery of T2Pt represents an original effort directed at the development of irreversible PCNA inhibitors and sets the stage for the discovery of analogues more selective for PCNA over other cellular nucleophiles.

  Proliferating cell nuclear antigen (PCNA) is an essential component for DNA replication and DNA damage response. Numerous proteins interact with PCNA through their short sequence called the PIP-box to be promoted to their respective functions. PCNA supports translesion DNA synthesis (TLS) by interacting with TLS polymerases through PIP-box interaction. Previously, we found a novel small molecule inhibitor of the PCNA/PIP-box interaction, T2AA, which inhibits DNA replication in cells. In this study, we created T2AA analogues and characterized them extensively for TLS inhibition. Compounds that inhibited biochemical PCNA/PIP-box interaction at an IC50 <5 mu M inhibited cellular DNA replication at 10 mu M as measured by BrdU incorporation. In cells lacking nucleotide-excision repair activity, PCNA inhibitors inhibited reactivation of a reporter plasmid that was globally damaged by cisplatin, suggesting that the inhibitors blocked the TLS that allows replication of the plasmid. PCNA inhibitors increased gamma H2AX induction and cell viability reduction mediated by cisplatin. Taken together, these findings suggest that inhibitors of PCNA/PIP-box interaction could chemosensitize cells to cisplatin by inhibiting TLS. (C) 2013 Elsevier Ltd. All rights reserved.
