library followed by a screening campaign at the solubleepoxidehydrolase (sEH). We identified meta-carboranyl alkylamides, -anilides, and -benzylamides as potent sEH inhibitors. Furthermore, we optimized the scaffolds and we derived structure-activity relationships. The most potent benzylamide 33 (MS1) was similar to a previously reported adamantane derivative and gave an IC50 value of 0.07 μM for meta-
m-Carboranyl amides have been synthesized via the one-pot one-step carbonylation reaction of 1-I-m-carborane with primary and secondary amines in the presence of a palladium catalyst and under carbon monoxide atmosphere (Heck reaction). Different catalysts, ligands, bases, and experimental conditions have been evaluated and the results in terms of yield and formation of by-products are discussed.
