Background:

WWL70 is a selective alpha/beta hydrolase domain 6 (ABHD6) inhibitor with an IC50 of 70 nM.

At 1 h after WWL70 (10 μM) treatment, 2-Arachidonoylglycerol (2-AG) is increased by 20% compare to untreated cells. At either 1 or 10 μM, WWL70 completely blocks the lipopolysaccharide (LPS)-induced increase of PGE2. The enhanced mRNA expression of mPGES-1 and mPGES-2 by LPS is also reduced by WWL70. The IC50 of WWL70 to inhibit the PGE2 biosynthesis is about 100 nM[2].

Although post-treatment with WWL70 at 5?mg/kg does not have any effect, treatment with WWL70 at 10?mg/kg improves the performance significantly. WWL70 treatment improves motor coordination of traumatic brain injury (TBI) mice in a concentration dependent manner. The latency to fall in animals treated with WWL70 at 5?mg/kg increases from 74.92±4.8 to 99.57±5.21 on day 3 (p<0.01) and from 87.32±4.42 to 100.14±3.56 on day 7 (p<0.05) post-injury when compare with the vehicle-TBI groups. At 10?mg/kg, WWL70 treatment improves motor coordination starting on day 1 post-injury. WWL70 treatment completely restores the ability of TBI mice to continuously alternate arms during Y maze exploration (69.67±4.98 %)[3].
