KML29, an O-hexafluoroisopropyl (HFIP) carbamate analogue of JZL184. is a potent and orally active monoacylglycerol lipase (monoglyceride lipase; MAGL; MGLL; MGL) inhibitor (IC50 = 5.9/15/43 nM against human/mouse/rat MAGL) that targets MAGL active site with greatly improved selectivity (rat/mouse ABHD6 IC50 = 1.60/4.87; no inhibitory activity against human/rat/mouse fatty acid amide hydrolase (FAAH) up to 50 μM). KML29 in vivo treatment results in a selective upregulation of 2-arachidonoyl glycerol (2-AG), but not N-arachidonoyl-ethanolamine (AEA) in mice (brain Emax ∼20 mg/kg p.o. or i.p.; peripheral Emax ∼1 mg/kg p.o.) and rats (brain Emax ∼40 mg/kg i.p.). KML29 reduces inflammatory and neuropathic nociceptive behaviour in animal studies without cannabimimetic side effects seen with dual FAAH & MAGL inhibition, chronic administration, however, leads to CB1 receptor desensitization as observed with other MAGL inhibitors.
