WWL123 Usage And Synthesis

Uses

WWL123 is a brain penetrant inhibitor of ABHD6 that shows 10-fold selectivity for ABHD6. This inhibition has shown to decrease seizure incidence in a genetic mouse model for juvenile Huntington’s disease.

Biological Activity

wwl123 is a brain-penetrant inhibitor of abhd6.the serine hydrolase a/b-hydrolase domain 6 (abhd6) has been reported to hydrolyze the most abundant endocannabinoid (ecb) in the brain, 2-arachidonoylglycerol (2-ag), and controls its availability at cannabinoid receptors.

in vitro

wwl123 was identified as a brain-penetrant inhibitor of abhd6 demonstrating over 10-fold selectivity for abhd6 compared to a panel of about 35 other serine hydrolases [1].

in vivo

in previous study, mice were pretreated with either vehicle or wwl123, and then they were treated with 50 mg/kg ptz. it was found that pretreatment with wwl123 could block seizure-related mortality, reduce the severity of seizure behaviors, reduce the number of gtc seizures per mouse, and reduce the frequency of myoclonic (mc) seizures as well. in addition, to test whether behavioral seizures exhibited by r6/2 mice are controlled by chronic blockade of the ecb signaling system, the authors treated mice with a daily injection of vehicle, sr1, or wwl123. results showed that wwl123 blocked the incidence of spontaneous behavioral seizures in r6/2 mice and there was no effect on duration of spontaneous seizures in response to chronic sr1 treatment vehicle [2].
