Biological Activity

Description

Lanabecestat (AZD3293, LY3314814) is an oral beta-secretase 1 cleaving enzyme (BACE) inhibitor with an inhibitory constant Ki of 0.4 nM.

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 AZD3293 with respect to secretion of Aβ40 and sAβPPβ is studied in a range of cellular models, the compound 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). AZD3293 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 of AZD3293. 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^[1].

In vivo

In vivo in mice, guinea pigs, and dogs, AZD3293 displays significant dose- and time-dependent reductions in plasma, cerebrospinal fluid, and brain concentrations of Aβ40, Aβ42, and sAβPPβ. In the dog PK study, the bioavailability of AZD3293 is determined to be 80% (F = 0.8). The preclinical data strongly support the clinical development of AZD3293, and patients with AD are currently being recruited into a combined Phase 2/3 study to test the disease-modifying properties of AZD3293^[1].

Protocol (from reference)

Cell Assay:^{^[1]}	Cell lines SH-SY5Y, SH-SY5Y overexpressing wild type AβPP, HEK293 cells overexpressing AβPP with the Swedish mutation (K595N/M596L), N2A cells, and primary cortical neurons isolated from fetal C57BL/6 mice (E16) or Dunkin-Hartley guinea pigs (E25-27) Concentrations -- Incubation Time 5 to 16 h Method The cells are incubated with different AZD3293 concentrations for 5 to 16 h, and the release of sAβPPβ, Aβ1-40, Aβ1-42, or sAβPPα into the medium is analyzed using specific commercial ELISA or kits from Meso Scale Discovery.
