The sodiumiodidesymporter (NIS) is responsible for the accumulation of iodide in the thyroid gland. This transport process is involved in numerous thyroid dysfunctions and is the basis for human contamination in the case of exposure to radioactive iodine species. 4‐Aryl‐3,4‐dihydropyrimidin‐2(1H)‐ones were recently discovered by high‐throughput screening as the first NIS inhibitors. Described herein
series of potentagonists of the bileacidreceptorTGR5 bearing a dihydropyridone scaffold was developed from a high-throughput screen. Starting from a micromolar hit compound, we implemented an extensive structure–activity-relationship (SAR) study with the synthesis and biological evaluation of 83 analogues. The project culminated with the identification of the potent nanomolar TGR5agonist 77A. We
The enantioselective carbene insertion into N–H bonds of anilines has been realized by cooperativecatalysis of ruthenium complexes and chiralphosphoricacids, providing the expected α-aryl glycines in moderate to good yields with high enantioselectivity. Typically, by slightly modifying the reaction conditions, this approach allows the N–H bond insertion reaction to be effective for both α-aryl and
