Description |
SA57 is a potent, selective FAAH inhibitor with IC50s of 3.2 nM and 1.9 nM for mouse and human FAAH. SA57 also inhibits the 2-arachidonoylglycerol hydrolases MAGL (IC50s of 410 nM and 1.4 μM for mouse and human MAGL) and mouse α/β-hydrolase domain-containing protein 6 (mABHD6; IC50 of 850 nM), but not other brain serine hydrolases[1][2].

Target |
IC50: 3.2 nM (Mouse FAAH) and 1.9 nM (Human FAAH); 410 nM (Mouse MAGL) and 1.4 μM (Human MAGL); 850 nM (Mouse ABHD6)[1]
|
In Vitro |
O-Aryl carbamate and N-aryl urea inhibitors have been shown to irreversibly inhibit FAAH by carbamylation of the enzyme’s serine nucleophile. SA57 exhibits clear time-dependent inhibition of FAAH and MAGL, suggesting a covalent mechanism of inactivation, presumably through carbamylation of the active site serine nucleophiles of these enzymes[1].

In Vivo |
SA57 (0.01-12.5 mg/kg; intraperitoneal injection; for 2 hours; C57Bl/6 mice) treatment shows distinct dose-responsive activity against brain serine hydrolases (FAAH, MAGL and ABHD6) in vivo[1]. Animal Model: C57Bl/6 mice[1] Dosage: 0.01 mg/kg, 0.05 mg/kg, 0.25 mg/kg, 1.25 mg/kg, 6.25 mg/kg, 12.5 mg/kg Administration: Intraperitoneal injection; for 2 hours Result: Showed distinct dose-responsive activity against brain serine hydrolases. Inhibited FAAH, MAGL and ABHD6 in vivo.
