WWL123 is a potent and selective ABHD6 inhibitor with an IC₅₀ of 430 nM. WWL123 crosses the blood-brain-barrier and inhibits ABHD6 in brain parenchyma. ABHD6 blockade by WWL123 exerts an antiepileptic effect in Pentylenetetrazole (PTZ)-induced epileptiform seizures and spontaneous seizures in R6/2 mice.
