  inflammatory disorders, and neurodegeneration. A novel, highly potent, orally bioavailable EP300/CBP histone acetyltransferase (HAT) inhibitor, CPI-1612 or 17, was developed from the lead compound 3. Replacement of the indole scaffold of 3 with the aminopyridine scaffold of 17 led to improvements in potency, solubility, and bioavailability. These characteristics resulted in a 20-fold lower efficacious
