描述 | CBP has acetyltransferase activity and affects cell proliferation and differentiation. CBP and the closely related p300 are recruited Wnt-responsive promotes through interactions with the C-terminal half of β-catenin. PRI 724 is a novel inhibitor for Wnt/β-catenin/CBP pathway with IC50 value of 150nM[1]. In vitro, PRI 724 exhibited concentration dependent cytotoxicity in concentration range of 5-100μM to head and neck carcinoma lines BICR6, UM-SCC-1, and oral keratinocyte cell lines CAL27, FaDu, H314, SCC-25, OKF4/TERT-1. PRI 724 also reduced the transcript level of Wnt target genes Axin2, MMP7, and BIRC5 in these cells. Treatment with 20μM PRI 724 showed ability to inhibit the migration of BICR6, CAL27, FaDu and SCC-25 cells. In addition, PRI 724 reduced the percentage of G0/G1 cells in CAL27, SCC-25 and UM-SCC-1 cell lines, but slightly increased the percentage of G0/G1 cells in the FaDu cell linePMID: 31089983. In vivo, administration of 30mg/kg PRI 724 once daily significantly improved the overall survival of the leukemia-bearing NSG mice[2]. Subcutaneous administration of 10mg/kg PRI 724 once daily for 5 days ameliorated bleomycin-induced pulmonary fibrosis in mice[3]. | ||
作用机制 | PRI 724 specifically disruption the interaction of CBP and β-catenin to inhibit Wnt/β-catenin/ CBP signaling pathway[3]. |
