A small library of dihydropyrimidin-2-ones (DHPMs) was synthesized and evaluated for their potency to block iodide entrapment in rat thyroid cells. Synthesis was achieved using the multicomponent Biginelli reaction. Twelve compounds were tested for the inhibition of sodiumiodidesymporter (NIS) in a cell-based assay. One newly synthesized derivative exhibited a remarkably strong activity, with a half-maximum

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.
