生物活性

AMG-8718 is a potent, selective and orally active BACE1 inhibitor with IC50 values of 0.0007, 0.005 µM for BACE1 and BACE2, respectively. AMG-8718 significantly decreases Aβ40 levels in the CSF and brain[1].

IC50 & Target[1]

BACE1

0.0007 μM (IC50)

BACE2

0.005 μM (IC50)

体外研究
(In Vitro)

AMG-8718 (compound 42) shows good stability in human and rat liver microsomes, hERG binding activity with an Ki value of >10 µM[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

体内研究
(In Vivo)

AMG-8718 (compound 42) (10 mg/kg; p.o.)shows significantly decreases Aβ40 levels in the CSF and brain[1].
AMG-8718 (i.v. for 2 mg/kg or p.o. for 5 mg/kg) shows good bioavailability of 70%, 96%,101% for rats, beagle dog, monkey, respectively[1].
AMG-8718 (30 mg/kg for; p.o.) dose-dependent decreases in both CSF and brain Aβ levels at 4 h time points with 50% Aβ reduction (EC50) values of 18 and 67 nM for CSF and brain respectively in rats[1].
AMG-8718 (2.5, 8, 16 mg/kg; i.v.; a series of three 30 min infusions) shows high unbound plasma concentrations with 0.298, 1.70, 3.62 µM at the end of each infusion in chloralose-anesthetized dogs[1].

Animal Model: Male Sprague-Dawley rats[1]
Dosage: 10 mg/kg
Administration: Oral gavage
Result: Significantly decreased Aβ40 levels in the CSF at the 4 h time point at 69%, produced a robust response in the brain with 48% reduction of Aβ40 levels.
Animal Model: Rats, beagle dog, monkey[1]
Dosage: 2, 5 mg/kg
Administration: I.v. for 2 mg/kg or p.o. for 5 mg/kg
Result: Showed moderate total clearance, moderate Vdss, and half-lives of ca. 5-8 h across all three species, and bioavailability was high (70–101%).
Animal Model: Rats[1]
Dosage: 30 mg/kg
Administration: P.o.
Result: Demonstrated dose-dependent decreases in both CSF and brain Aβ levels at 4 h and 8 h time points.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
