    Product Description

    RBPJ inhibitor-1 is an inhibitor of recombination signal binding protein for immunoglobulin kappa J region (RBPJ; IC50 = 0.18 µM in a reporter assay).1 It also inhibits the protein-protein interaction between RBPJ and the neurogenic locus notch homolog protein 2 (Notch2) intracellular domain (NICD) and the protein-protein interaction between RBPJ and small histidine-alanine-rich protein (SHARP) in cell-free assays. RBPJ inhibitor-1 (15 µM) induces cell cycle arrest at the G2/M phase and apoptosis in UT-SCC-42B squamous cell carcinoma cells.2 It reduces tumor volume in D. rerio larvae injected with UT-SCC-42B cells when administered in the tank water at a concentration of 5 µM.

    WARNING This product is not for human or veterinary use.
