시험관 내(In vitro) LY2886721 is an oral, small molecule of β-site amyloid protein cleaving enzyme (BACE) inhibitor with the potential to inhibit the synthesis of β-amyloid and thereby to slow the clinical progression of AD. This compound can also targetγ-secretase to nhibit the synthesis of β-amyloid. It inhibits recombinant hBACE1 with an IC50 of 20.3 nM. In cellular assays, this chemical inhibits Abeta with an IC50 of 18.7 nM and 10.7 nM, HEK293Swe and PDAPP neuronal culture, respectively. It has high selectivity against key off-target proteases, which efficiently translates in vitro activity into robust in vivo amyloid β lowering in nonclinical animal models. Assessment of its activity against hBACE2 demonstrates an IC50 of 10.2 nM. Assessment of the compound's activity against cathepsin D, pepsin, renin, or other important aspartyl proteases shows essentially no inhibition (IC50 >100,000 nM), suggesting that activity against these common aspartyl proteases is unlikely to be significant.
생체 내(In Vivo) Oral administration of LY2886721 to PDAPP mice produces dose-dependent reductions in brain Abeta, C99 and sAPPbeta. Brain Abeta levels are decreased ∼20%-65% relative to vehicle-treated groups three hours after a 3-30 mg/kg dose of this compound. Brain C99 and sAPPb levels also are reduced in a dose-dependent manner consistent with BACE1 inhibition in vivo. The pharmacodynamic responses to this chemical persists out to 9 hours post dose in brains of PDAPP mice. Pharmacodynamic studies in beagle dog reveal robust and sustained reductions in plasma Abeta following 1 mg/kg dosing. Central effects of BACE1 inhibition in dog are manifested by a 50% reduction in CSF Abeta at 9 hours after a 0.5 mg/kg dose. The geometric mean terminal elimination t1/2 is determined to be 17.2 h (range 8.19-36.3 h). The geometric mean apparent oral clearance is 34.8 L/h (38% CV) and the apparent volume of distribution during the terminal phase was 863 L (56% CV) across dose levels. This compound is freely permeable across the blood-brain barrier.
