Lanabecestat (AZD3293) is a potent, orally active and blood-brain barrier penetratingBACE1inhibitor with aK_iof 0.4 nM. Lanabecestat is used for the research of Alzheimer's disease^[1].

Ki: 0.4 nM (BACE1)^[1]

Lanabecestat acts as a full inhibitor of BACE1in vitro, with a competitive and reversible mechanism of action towards the hBACE1 active site. Lanabecestat displays a very high target affinity and a markedly slow target off-rate. The off-rate of lanabecestat has an estimated t1/2 of approximately 9 h. Lanabecestat 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). Thein vitroplasma protein binding of lanabecestat is determined by equilibrium dialysis using mouse, rat, guinea pig, dog, and human plasma. The compound is stable in the plasma of these species for at least the duration of thein vitroincubation period. The unbound fractions are 1.3% to 1.8% for mice, 4.2% to 5.9% for rats, 8.3% to 10.3% for guinea pigs, 9.4% to 10.3% for dogs, and 7.7% to 9.4% for human plasma. The mean blood:plasma ratio of 0.7 in human blood indicates no significant association with red blood cells. The free fraction in the brain tissue binding assay is 4.5%^[1].

In mice, guinea pigs, and dogs, lanabecestat displays significant dose- and time-dependent reductions in plasma, cerebrospinal fluid, and brain concentrations of Aβ₄₀, Aβ₄₂, and sAβPPβ^[1].
