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.
Orally active, potent and highly selective monoacylglycerol lipase (MAGL) inhibitor with in vivo analgesic efficacy without cannabimimetic side effects.
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
The modulation of the brain endocannabinoid system has been identified as an option to treat neurodegenerative diseases including Parkinson's disease (PD). Especially the elevation of endocannabinoid levels by inhibition of hydrolytic degradation represents a valuable approach. To evaluate whether monoacylglycerol
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
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

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.
