faah/magl-in-2

FAAH MAGL-IN-2 是一种有效的，可逆的，具有口服活性且可透过血脑屏障的 FAAH 和 MAGL 抑制剂，其IC50值分别为 11 nM 和 36 nM (b>Ki 值分别为 28 nM 和 60 nM)。FAAH MAGL-IN-2 有研究神经性疼痛的潜力而不引起运动障碍。

KML29 是一种口服具有活性的、高度选择性的不可逆 MAGL 抑制剂，其对小鼠、大鼠和人的 IC50值分别为15 nM、43 nM 和 5.9 nM。它对 FAAH 在内的其他中心和外周丝氨酸水解酶的交叉反应极小。

URB754 is a potent and noncompetitive inhibitor of monoacylglycerol lipase (MAGL), exhibiting an IC50 value of 200 nM for the recombinant rat brain enzyme. However, it does not inhibit human recombinant, rat brain, or mouse brain MAGL at concentrations up to 100 μM. There is evidence that the MAGL inhibitory activity of URB754 may be attributed to the impurity bis(methylthio)mercurane (IC50 = 11.9 nM for rat recombinant MAGL) that is found in commercial preparations. URB754 inhibits rat brain fatty acyl amide hydrolase (FAAH) with an IC50 value of 32 μM and binds weakly to the rat central cannabinoid (CB1) receptor with an IC50 value of 3.8 μM. It does not inhibit COX-1 or COX-2 at concentrations up to 100 μM. Inhibition of MAGL hydrolysis of 2-arachidonoyl glycerol (2-AG) is associated with enhanced stress-induced analgesia and may represent a novel drug target in pain and stress management.

JZL 184 是不可逆的、选择性的MAGL 抑制剂，对MAGL 的选择性比 FAAH 高 300 倍以上。它可阻断脑膜中的 2-花生四烯酸甘油酯 (2-AG) 的水解 (IC50为 8 nM)。

MAGL-IN-4 (His121 ARG57) 是选择性的、口服有效的、可透过血脑屏障的、可逆的单酰基甘油脂肪酶抑制剂，IC50=6.2 nM。它主要通过大脑中选择性抑制 MAGL 增加 2-花生四烯酰甘油水平来增强内源性大麻素信号。
