Biochem/physiol Actions

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.

Since monoacylglycerol lipase (MAGL) has been firmly established as the predominant catabolic enzyme of the endocannabinoid 2-arachidonoylglycerol (2-AG), a great need has emerged for the development of highly selective MAGL inhibitors. Here, we tested the in vivo effects of one

The endocannabinoids 2-arachidonoyl glycerol (2-AG) and N-arachidonoyl ethanolamine (anandamide) are principally degraded by monoacylglycerol lipase (MAGL) and fatty acid amide hydrolase (FAAH), respectively. The recent discovery of O-aryl carbamates such as JZL184 as selective MAGL inhibitors has enabled functional investigation

Systemic activation of cannabinoid receptors often induces biphasic effects on emotional memory and anxiety depending on the levels of emotional arousal associated to the experimental context. The basolateral nucleus of the amygdala (BLA) represents a crucial structure for the ability

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease of the motor neuron system with limited therapeutic options. While an increasing number of ALS patients can be linked to a small number of autosomal-dominantly inherited cases, most cases are termed

Gabapentin is commonly prescribed for nerve pain but may also cause dizziness, sedation and gait disturbances. Similarly, inhibition of the endogenous cannabinoid enzyme monoacylglycerol lipase (MAGL) has antinociceptive and anti-inflammatory properties but also induces sedation in mice at high doses.
