General description

A cell-permeable pyrazinopyrimidinecarboxamide that competes against β-catenin for CBP (CREB-binding protein) binding (5 to 10 µM for 24 h in SW480 and C2C12 cultures) and selectively prevents CBP- but not p300-, dependent TCF/β-catenin transcriptional regulations both in cultures in vitro (5 to 25 µM in SW480, HCT116, rat RLT-6TN, and primary human IPF lung fibroblasts; 4 to 24 h) and in mice in vivo (5 mg/kg/day via osmotic pump infusion), while not affecting CBP-dependent transcriptional activities mediated by the AP-1 or CRE complex. Selective blockage of CBP/TCF/β-catenin complex formation by ICG-001 is shown to reactivate p300//TCF/β-catenin-mediated neuronal differentiation upon NGF stimulation in PS-1 L286V mutant-expressing PC-12 cultures (cell population with neurite outgrowth = 90% and 17% of wt PS-1 control level, respectively, with or without 10 µM ICG-001) and be efficacious in alleviating bleomycin- (0,08 units/50 µL/mouse; administered intranasally; Cat. No. 203401) induced pulmonary fibrosis in mice (5 mg/kg/day via osmotic pump infusion; 10 d treatment starting 1 d before bleomycin induction or 21 d treatment starting d 21 post bleomycin induction).
