AZD-2184
AZD-2184 is a β-amyloid (Aβ(1-40)) fibril binder with blood-brain barrier permeability, exhibiting a Kd of 8.4 nM for hAβ(1-40). AZD-2184 binds to the same site as CPIB, shows low levels of non-specific binding to brain tissue, rapidly enters and clears from the brain tissue of normal rats, and binds reversibly to plaques in vivo. The radiolabeled form of AZD-2184 can serve as a PET ligand for the visualization of Aβ deposits. AZD-2184 is applicable to research related to Alzheimer's disease.

製品説明
体外実験
[3H]AZD2184 (13-100 nM) binds to hAβ(1-40) fibrils with high affinity at a Kd of 8.4 nM, and a secondary low-affinity binding site exists at higher concentrations[1].
AZD2184 (30 min) competively binds to Aβ(1-40) fibrils, with a Ki of 19.7 nM in displacing [3H]AZD2184, confirming its mutual displaceability with PIB[1].

体内実験
[3H]AZD-2184 (0.3 nmol/kg; intravenous injection; single 30-second infusion) binds reversibly to amyloid plaques in APP/PS1 mice, with a signal-to-background ratio twice that of [3H]PIB, and its labeling level decreases significantly at 40 minutes after administration[1].

Animal Model:APP/PS1 (transgenic, approximately 18 months old)[1]
-
Dosage:0.3 nmol/kg
-
Administration:i.v.; single 30-second infusion
-
Result:Labeled amyloid plaques with a distribution matching [3H]PIB, but with twice the signal-to-background ratio at 10 minutes post-administration.
Showed plaque labeling that declined significantly over time, with significantly lower levels observed at 40 and 80 minutes compared to 10 and 20 minutes post-injection (p = 0.0003).
