AZD3839

AZD3839 is a novel inhibitor of BACE1 with IC50 value of 4.8μM [1].

AZD3839 has been reported to inhibit human BACE1 activity in a biochemical FRET assay. In addition, AZD3839 has also been reported to inhibit the release of sAPPβs from human SH-SY5Y cells, mouse N2A cells and mouse and guinea pig primary cortical neurons. Moreover, AZD3839 has been revealed to effectively decrease the cerebrospinal fluid (CSF), plasma, and brain Aβ levels in guinea pig, mouse and non-human primate. AZD3839 has also been revealed to decrease the levels of Aβ40 secreted from C57BL/6 mouse primary cortical neurons, N2A cells (mouse neuroblastoma), and Dunkin-Hartley guinea pig primary cortical neurons, with IC50 values of 50.9, 32.2, and 24.8 nmol/liter, respectively [2].
