      Description
      OverviewA cell-permeable quinolinyl-dihydropyrazolyl-oxobutanoic acid compound that is shown to target human Replication Protein A (RPA) via primarily the oligosaccharide/oligonucleotide-binding (OB) folds of DNA-bonding domains A & B (DBD-A/B) in the p70 subunit, effectively inhibiting its DNA-binding activity as well as that of Schizosaccharomyces pombe telemere end-binding protein Pot1 (IC50= 12.9 µM and 15.7 µM, respectively), but not Xeroderma pigmentosum group A protein (XPA) involved in the nucleotide excision repair (NER) pathway or E. coli SSB. Reported to induce cell cycle G1-arrest and decrease Annvex V-/PI- healthy cell population (by 50%; 30.8 µM for 48 h) in H460 non-small cell lung carcinoma (NSCLC) cultures with minimal cytotoxicity against freshly isolated human PBMC. Potentiates cisplatin (Cat. No. 232120) and etopside (Cat. No. 341205) cytotoxicity in H460 cultures in a synergistic manner.

Reported to cause decreased nuclear RPA staining (50 µM for 3 h), cell cycle G1-arrest (75 to 100 µM), and a drop in Annvex V-/PI- healthy cell population (by 50%; 30.8 µM for 48 h) in H460 non-small cell lung carcinoma (NSCLC) cultures with minimal cytotoxicity against freshly isolated human PBMC. Potentiates cisplatin (Cat. No. 232120) and etopside (Cat. No. 341205) cytotoxicity in H460 cultures in a synergistic manner, consistent with blockage of RPA-mediated NER pathway.
