Despite over a decade of drug discovery efforts, the identification of brain-penetrant BACE1 inhibitors that substantially lower CNS Aβ levels following systemic administration remains challenging. In this report we describe structure-based optimization of a series of brain-penetrant BACE1 inhibitors derived from an iminopyrimidinone scaffold. Application of structure-based design in tandem with control of physicochemical properties culminated in the discovery of compound 16, which potently reduced cortex and CSF Aβ40 levels when administered orally to rats.

Herein we report SAR development in the S3 and F 0 subsites of BACE1 for this series, the synthetic approaches employed in this effort, and in vivo data for the optimized compound.
