By using the famous Wilkinson's catalyst, N-alkylation of sulfonamides can be easily realized under mild aerobic conditions by using alcohols as the alkylating reagent, giving monoalkylated sulfonamides in high yields and selectivities with water produced as the only byproduct. This advantageous aerobic method is potentially general in substrate scope that it can also be applied to other amides, amines and alcohols.

Our previous research showed that N-carboxy-phenylsulfonyl hydrazide (scaffold A) could reduce LPS-stimulated PGE2 levels in RAW 264.7 macrophage cells by an inhibition of mPGES-1 enzyme. However, a number of scaffold A derivatives showed the drawbacks such as the formation of regioisomers and poor liver metabolic stability. In order to overcome these synthetic and metabolic problems, therefore, we decided to replace N-carboxy-phenylsulfonyl hydrazide (scaffold A) with N-carboxy-phenylsulfonamide (scaffold B) or N-amido-phenylsulfonamide frameworks (scaffold C) as a bioisosteric replacement. Among them, MPO-0186 (scaffold C) inhibited the production of PGE2 (IC50: 0.24 μM) in A549 cells via inhibition of mPGES-1 (IC50: 0.49 μM in a cell-free assay) and was found to be approximately 9- and 8-fold more potent than MK-886 as a reference inhibitor, respectively. A molecular docking study theoretically suggests that MPO-0186 could inhibit PGE2 production by blocking the PGH2 binding site of mPGES-1 enzyme. Furthermore, MPO-0186 demonstrated good liver metabolic stability and no significant inhibition observed in clinically relevant CYP isoforms except CYP2C19. This result provides a potential starting point for the development of selective and potent mPGES-1 inhibitor with a novel scaffold.

The iridium complex [Cp?Ir(biimH2)(H2O)][OTf]2 (Cp? = η5-pentamethylcyclopentadienyl, biimH2 = 2,2′-biimidazole) was synthesized and developed as a new-type of water-soluble metal-ligand bifunctional catalyst for the N-alkylation of poorly nucleophilic sulfonamides with alcohols in water. In the presence of catalyst (1 mol%) and Cs2CO3 (0.1 equiv.), a series of desirable products was obtained in 74-91% yields under microwave irradiation. Mechanistic experiments revealed that the presence of NH units in the imidazole ligand is crucially important for the catalytic activity of the iridium complex. Notably, this research would facilitate the process of water-soluble metal-ligand bifunctional catalysis for the hydrogen autotransfer process.
