AM 1172

Biological Activity

Metabolically stable anandamide uptake inhibitor (IC₅₀ = 2.1 - 2.5 μM) and fatty acid amide hydrolase (FAAH) inhibitor (K_i = 3.18 μM). Inhibits N-arachidonylethanolamine (AEA) accumulation (IC₅₀ = 24 μM) and hydrolysis (K_i = 3 μM), and inhibits N-palmitoylethanolamine (PEA) hydrolysis (IC₅₀ = 36 μM) in cerebellar granule neurons. Also acts as a non-selective cannabinoid receptor partial agonist (EC₅₀ values are 189 and 271 nM at CB₂ and CB₁ receptors respectively).

Background References

1. Anandamide uptake is consistent with rate-limited diffusion and is regulated by the degree of its hydrolysis by fatty acid amide hydrolase.
