General description

A cell-permeable pyridinylvinyl-quinazolinone compound that is shown to specifically inhibit human RAD51 (IC50 = 27.4 µM). Does not affect RecA even at much higher concentration (~250 µM). Directly interacts with RAD51 (Kd = 5.6 µM), and disrupts its binding to DNA and nucleoprotein filament formation. Blocks double-strand break-induced homologous recombination and enhances sensitivity of cells to Cisplatin (Cat. No. 232120) and Mitomycin C (Cat. No. 47589), (Cat. No. 475820). Diminishes co-aggregate formation between RAD51-ssDNA filament and dsDNA. RAD51-Stimulatory Compound-1, RS-1 (Cat. No. 553510) is also available.

The PSMC3IP-MND1 heterodimer promotes meiotic D loop formation before DNA strand exchange. In genome-scale CRISPR-Cas9 mutagenesis and interference screens in mitotic cells, depletion of PSMC3IP or MND1 causes sensitivity to poly (ADP-Ribose) polymerase inhibitors (PARPi) used in cancer treatment. PSMC3IP

DNA replication and transcription generate DNA supercoiling, which can cause topological stress and intertwining of daughter chromatin fibers, posing challenges to the completion of DNA replication and chromosome segregation. Type II topoisomerases (Top2s) are enzymes that relieve DNA supercoiling and

Ovarian cancer is the most lethal gynecological malignancy. Abnormal homologous recombination repair, high level of reactive oxygen species (ROS) and upregulation of antioxidant genes are characteristic features of ovarian cancer. However, the molecular mechanisms governing the redox homeostasis in ovarian
