Enantioselective 1-(α-alkyl-α-phenylmethyl)-3-(3-phenylpropyl)urea inhibitor of soluble epoxide hydrolase was discovered.
The S-isomer of 8e showed 125 fold more active than its R-isomer.
Restriction of the free rotation of two α-groups with fused bicyclic moiety abolishes the selectivity.
These urea analogs are specific inhibitor of sEH without inhibition of mEH.
