Inhibition of multiple enzymes of the arachidonic acid cascade leads to synergistic anti-inflammatory effects. Merging of 5-lipoxygenase (5-LOX) and soluble epoxide hydrolase (sEH) pharmacophores led to the discovery of a dual 5-LOX/sEH inhibitor, which was subsequently optimized in terms of potency toward both targets and metabolic stability. The optimized lead structure displayed cellular activity in human polymorphonuclear leukocytes, oral bioavailability, and target engagement in vivo and demonstrated profound anti-inflammatory and anti-fibrotic efficiency in a kidney injury model caused by unilateral ureteral obstruction in mice. These results pave the way for investigating the therapeutic potential of dual 5-LOX/sEH inhibitors in other inflammation- and fibrosis-related disease models.

Mizoroki-Heck reactions, which are well-known for aryldiazonium salts and which have recently been described for arylhydrazines, have now been extended to phenyldiazenes. In situ generation of phenyldiazenes from azocarboxylates allowed clean and selective reactions with styrenes, acrylates, and acrylamides using palladium(II) acetate in the presence of silver(I) acetate or hydrogen peroxide as oxidant. Hydrogen peroxide was thereby shown to be a cheap and broadly applicable alternative for the established palladium-silver(I) system.

A set of the title compounds having different substituents (R1, R2) on their phenyl groups was synthesized to find σ receptor binding affinity. Among the compounds, 2b (R1=R2=Cl) has the most potent σ1-binding activity, while 2a (R1=R2=H, SA4503) was most selective to σ1 over σ2 receptor. The crystal structures of 2a and 2b were shown, by X-ray crystallography, to be similar except for the one torsional angle of their propylene parts. Quantitative structure-activity relationship study suggested the affinity of the compounds to the σ1 receptor was dependent on the electronic feature, Swain-Lupton's R or S(π) that was derived by molecular orbital method, of R1 and R2.
