Mechanism of Action

Targets/IC₅₀/Ki	BACE (Cell-free assay) 0.4 nM(Ki)
In vitro	Lanabecestat (AZD3293, LY3314814) is a potent, highly permeable, orally active, blood-brain barrier (BBB) penetrating, BACE1 inhibitor with unique slow off-rate kinetics. When the potency of this compound with respect to secretion of Aβ40 and sAβPPβ is studied in a range of cellular models, it displays pM potency in primary neuron cultures from mice and guinea pigs and in SH-SY5Y cells over-expressing AβPP (IC50 = 610 pM, 310 pM, and 80 pM, respectively). It is also tested in a panel of more than 350 in vitro radioligand binding and enzyme activity assays, covering a diverse range of receptors, ion channels, transporters, kinases, and enzymes, up to a concentration of 10μM. A few significant responses are observed, but these had at least a 1,000-fold selectivity against BACE1, thus indicating specificity to BACE1. The off-rate of AZD3293 has an estimated t_1/2 of approximately 9 h.
In vivo	Lanabecestat (AZD3293) displays significant dose- and time-dependent reductions in plasma, cerebrospinal fluid, and brain concentrations of Aβ40, Aβ42, and sAβPPβ in vivo in mice, guinea pigs, and dogs. In the dog PK study, its bioavailability is determined to be 80% (F = 0.8). The preclinical data strongly support the clinical development of this compound, and patients with AD are currently being recruited into a combined Phase 2/3 study to test its disease-modifying properties.
