1.Whats KML29(1380424-42-9) ?

 

KML29(1380424-42-9) is a potent and orally active monoacylglycerol lipase inhibitor 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(1380424-42-9) 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(1380424-42-9)reduces inflammatory and neuropathic nociceptive behaviour in animal studies without cannabimimetic side effects seen with dual FAAH & MAGL, chronic administration, however, leads to CB1 receptor desensitization as observed with other MAGL inhibitors.

3.How does KML-29 (1380424-42-9)work?

 

we tested KML29(1380424-42-9) in murine inflammatory (i.e. carrageenan) and sciatic nerve injury pain models, as well as the diclofenac-induced gastric haemorrhage model. KML29(1380424-42-9) was also evaluated for cannabimimetic effects, including measurements of locomotor activity, body temperature, catalepsy, and cannabinoid interoceptive effects in the drug discrimination paradigm. 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 such compound, KML29 (1,1,1,3,3,3-hexafluoropropan-2-yl 4-(bis(benzo[d][1,3]dioxol-5-yl)(hydroxy)methyl)piperidine-1-carboxylate).We get the key results: KML29(1380424-42-9) attenuated carrageenan-induced paw oedema and completely reversed carrageenan-induced mechanical allodynia. These effects underwent tolerance after repeatedadministration of high-dose KML29(1380424-42-9), which were accompanied by cannabinoid receptor 1 (CB1 ) receptor desensitization. Acute or repeated KML29(1380424-42-9) administration increased 2-AG levels and concomitantly reduced arachidonic acid levels, but without elevating anandamide (AEA) levels in the whole brain. Furthermore, KML29 partially reversed allodynia in the sciatic nerve injury model and completely prevented diclofenac-induced gastric haemorrhages. CB1 and CB2 receptors played differential rolesin these pharmacological effects of KML29(1380424-42-9). In contrast, KML29 did not elicit cannabimimetic effects, including catalepsy, hypothermia and hypomotility. Although KML29did not substitute for Δ(9) -tetrahydrocannabinol (THC) in C57BL/6J mice, it fullyand dose-dependantly substituted for AEA in fatty acid amide hydrolase (FAAH) (-/-) mice, consistent with previous work showing that dual FAAH and MAGL inhibitionproduces THC-like subjective effects.

 

 


 

4.A Experience about  KML-29(1380424-42-9)

 

In the present study, we tested KML29 in murine inflammatory (i.e. carrageenan) and sciatic nerve injury pain models, as well as the diclofenac-induced gastric haemorrhage model. KML29 was also evaluated for cannabimimetic effects, including measurements of locomotor activity, body temperature, catalepsy, and cannabinoid interoceptive effects in the drug discrimination paradigm.

 

KEY RESULTS:

KML29 (1380424-42-9)attenuated carrageenan-induced paw oedema and completely reversed carrageenan-induced mechanical allodynia. These effects underwent tolerance after repeated administration of high-dose KML29(1380424-42-9), which were accompanied by cannabinoid receptor 1 (CB1 ) receptor desensitization. Acute or repeated KML29 administration increased 2-AG levels and concomitantly reduced arachidonic acid levels, but without elevating anandamide (AEA) levels in the whole brain. Furthermore, KML29(1380424-42-9) partially reversed allodynia in the sciatic nerve injury model and completely prevented diclofenac-induced gastric haemorrhages. CB1 and CB2 receptors played differential roles in these pharmacological effects of KML29. In contrast, KML29 (1380424-42-9)did not elicit cannabimimetic effects, including catalepsy, hypothermia and hypomotility. Although KML29 did not substitute for Δ(9) -tetrahydrocannabinol (THC) in C57BL/6J mice, it fully and dose-dependantly substituted for AEA in fatty acid amide hydrolase (FAAH) (-/-) mice, consistent with previous work showing that dual FAAH and MAGL inhibition produces THC-like subjective effects.

 

CONCLUSIONS AND IMPLICATIONS:

These results indicate that KML29, a highly selective MAGL inhibitor, reduces inflammatory and neuropathic nociceptive behaviour without occurrence of cannabimimetic side effects.
