CPN cat Inhibitors

The CPN cat Inhibitors can primarily be associated with compounds that disrupt the function of enzymes involved in DNA processing, replication, and repair. Key among these are the quinolone antibiotics like Ciprofloxacin, Enoxacin, and Lomefloxacin, which target bacterial DNA gyrase and topoisomerase IV, crucial for DNA replication and repair. The inhibition of these enzymes results in stalled DNA replication, which can lead to bacterial cell death. Apart from the quinolones, several compounds, including ICRF-193, Merbarone, and Aclacinomycin A, focus on topoisomerase II, a pivotal enzyme in DNA replication, repair, and segregation. By binding to and inhibiting this enzyme, these compounds can induce DNA breaks, thereby halting replication and other DNA processes. For instance, Doxorubicin, a well-known intercalating agent, integrates into the DNA and also inhibits topoisomerase II, resulting in double-strand breaks. Collectively, these CPN cat Inhibitors offer a robust suite of tools to target and inhibit DNA-related processes, especially recombination and segregation, central to the function of the CPN cat protein.
