PF-06751979 is a potent, brain penetrant, β-site amyloid precursor protein cleaving enzyme 1 ( BACE1 ) inhibitor with an IC 50 of 7.3 nM in BACE1 binding assay.
In Vitro
PF-06751979 shows improved selectivity over BACE2 (IC 50 =194 nM) in binding (27-fold) relative to the literature examples and across multiple chemical series in BACE1 program. PF-06751979 also inhibits BACE1 and BACE2 in a fluorescent polarization (FP) assay with IC 50 s of 26.9 nM and 238 nM, respectively. PF-06751979 has excellent potency at BACE1 in binding or FP assay formats along with cellular activity looking at production of sAPPβ in H4 cells with an IC 50 of 5 nM. MCE has not independently confirmed the accuracy of these methods. They are for reference only.
In Vivo
PF-06751979 displays excellent brain penetration, potent in vivo efficacy, and broad selectivity over related aspartyl proteases including BACE2. Acute administration of PF-06751979 yields a robust dose-responsive and time-dependent reduction of cerebral spinal fluid (CSF) Aβx-40 with peak inhibition at 3 h of >77%. To determine if the reduction in brain and CSF Aβ is maintained during sustained exposure to PF-06751979, a 5 day subchronic study is executed, dosing once daily by subcutaneous (SC) administration (10 or 50 mg/kg/day). Brain and CSF samples are collected on day 5, following the last dose. PF-06751979 produces a dose-responsive and time-dependent inhibition of Aβ42 in mouse brain. At the 50 mg/kg/day dose, maximal brain lowering is 63% at 7 to 9 h. Administration of PF-06751979 (10 or 50 mg/kg/day for 5 days) produces a dose-responsive and time-dependent inhibition of Aβx-40 in mouse CSF resulting in 77% inhibition of CSF at 3 h post-final 50 mg/kg dose . MCE has not independently confirmed the accuracy of these methods. They are for reference only.
