A simple and rapid access to a variety of 4(5)-arylated imidazoles via palladium-catalyzed Suzuki–Miyaura cross-coupling reaction is described. Coupling parameters were screened for efficient C-4 arylation of N-unprotected 4-iodoimidazole with a broad range of boronic acids under microwave irradiation. Twenty-one imidazole derivatives were synthesized in modest to excellent yields in short reaction
copper complex bearing a 'histidine brace' is synthesised and characterised as an active-site model of mononuclear copper monooxygenases such as lytic polysaccharide monooxygenases (LPMOs) and particulate methane monooxygenase (pMMO). The complex has similar structural and functional features to the activesites of the enzymes.

cancer immunotherapy. Thioredoxin reductase (TrxR) enzymes are reactive oxygen species (ROS) modulators that are involved in the tumor cell growth and survival processes. The 4-phenylimidazole scaffold is well-established as useful for indoleamine 2,3-dioxygenase 1 (IDO1) inhibition, while piperlongumine (PL) and its derivatives have been reported to be inhibitors of TrxR. To take advantage of both
