AZD3839

AZD3839 is a potent and selective BACE1 inhibitor. AZD3839 is clinical candidate for the treatment of Alzheimer disease. AZD3839 inhibits BACE1 activity, Aβ and sAPPβ release from modified and wild-type human SH-SY5Y cells and mouse N2A cells as well as from mouse and guinea pig primary cortical neurons. Selectivity against BACE2 and cathepsin D was 14 and >1000-fold, respectively. AZD3839 exhibits dose- and time-dependent lowering of plasma, brain, and cerebrospinal fluid Aβ levels in mouse, guinea pig, and non-human primate. AZD3839 effectively reduces the levels of Aβ in brain, CSF, and plasma in several preclinical species.
