CPI-1612 is a highly potent, orally active EP300/CBP histone acetyltransferase (HAT) inhibitor with an IC 50 of 8.1 nM for EP300 HAT. CPI-1612 has an anticancer activity.

Solid

IC50: 8.1 nM (EP300 HAT)

CPI-1612 inhibits full length EP300 and full length CBP with IC50 values <0.5 nM and 2.9 nM, respectively.
CPI-1612 inhibits H3K18Ac MSD (H3K18 = histone 3 lysine 18, MSD = meso scale discovery) and JEKO-1 cell proliferation with with IC50 values 14 nM and <7.9 nM, respectively.
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). has not independently confirmed the accuracy of these methods. They are for reference only.

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.
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).
A single dose of CPI-1612 is administered orally to CD-1 mice and brain and plasma exposures of CPI-1612 are measured

Room temperature in continental US; may vary elsewhere.
