CPI-1612 is a highly potent, orally activeEP300/CBPhistone acetyltransferase(HAT)inhibitor with anIC₅₀of 8.1 nM forEP300 HAT. CPI-1612 has an anticancer activity^[1].

IC50: 8.1 nM (EP300 HAT)^[1]

CPI-1612 inhibits full length EP300 and full length CBP with IC₅₀values<0.5 nM and 2.9 nM, respectively^[1].
CPI-1612 inhibits H3K18Ac MSD (H3K18 = histone 3 lysine 18, MSD = meso scale discovery) and JEKO-1 cell proliferation with with IC₅₀values 14 nM and<7.9 nM, respectively^[1].
CPI-1612 (compound 17) shows weak activity in a hERG binding assay (IC₅₀= 10.4 μM) and displayed moderate inhibition of CYP2C8 (IC₅₀= 1.9 μM) and CYP2C19 (IC₅₀= 2.7 μM)^[1].

CPI-1612 (compound 17; 0.5 mg/kg; oral administration; twice a day; for 4 weeks) treatment shows 67% tumor growth inhibition (TGI) with concomitant reduction of H3K27Ac in plasma and reduction of H3K18Ac in the tumor^[1].
While the oral exposure of CPI-1612 (compound 17) in dogs (0.5 mg/kg IV; 1.0 mg/kg PO; clearance = 0.42 L/h/kg, V_ss= 3.7 L/kg, T_1/2= 5.5 h, F% = 71; AUC/dose = 1691 h·mg/mL) and mice (1 mg/kg IV; 5 mg/kg PO; clearance = 3.8 L/h/kg, V_ss= 2.0 L/kg, T_1/2= 0.98 h, F% = 79; AUC/dose = 211 h·mg/mL) is good, the exposure in rats is limited by poor bioavailability (1.0 mg/kg IV; 5.0 mg/kg PO; clearance = 2.6 L/h/kg, V_ss= 1.8 L/kg, T_1/2= 1.2 h, F% = 9; AUC/dose = 35.6 h·mg/mL)^[1].
A single dose of CPI-1612 is administered orally to CD-1 mice and brain and plasma exposures of CPI-1612 are measured at 0.25, 0.5, 1.0, 2.0, 4.0, and 8.0 h. CPI-1612 is highly brain-penetrant, showing a brain-to-plasma ratio of 0.35 after a single oral dose^[1].
