Beta-site amyloid precursor protein cleaving enzyme1 (BACE1) is one of the key enzymes involved in the processing of the amyloid precursor protein (APP) and formation of amyloid beta peptide (Abeta) species. Since cerebral deposition of Abeta species might be critical for the pathogenesis of Alzheimers disease, BACE1 has emerged as a key target for the treatment of this disease. Here, we report the discovery and comprehensive preclinical characterization of AZD3839, a potent and selective inhibitor of human BACE1. AZD3839 was identified using fragment-based screening and structure-based design. In a concentration-dependent manner, AZD3839 inhibited BACE1 activity in a biochemical FRET assay, Abeta and sAPPbeta release from modified and wild type human SH-SY5Y cells, mouse N2A cells, as well as from mouse and guinea pig primary cortical neurons. Selectivity against BACE2 and Cathepsin D were 14 and &gt;1000 fold, respectively. AZD3839 exhibited dose- and time-dependent lowering of plasma, brain and CSF Abeta levels in mouse, guinea pig and non-human primate. Pharmacokinetic/ Pharmacodynamic analyses of mouse and guinea pig data showed a good correlation between the potency of AZD3839 in primary cortical neurons and in vivo brain effects. These results suggest that AZD3839 effectively reduce the levels of Abeta in brain, CSF and plasma in several preclinical species. It might therefore have disease-modifying potential in the treatment of Alzheimers disease and related dementias. Based on the overall pharmacological profile and its drug like properties, AZD3839 has been progressed into Phase 1 clinical trials in man.
