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 sodium iodide symporter (NIS) in a cell-based assay. One newly synthesized derivative exhibited a remarkably strong activity, with a half-maximum
合成了一个小分子二氢嘧啶-2-酮(DHPM)库,并评估了它们在大鼠甲状腺细胞中阻断碘化物截留的能力。使用多组分Biginelli反应可实现合成。在基于细胞的分析中测试了十二种化合物对碘化钠同向转运蛋白(NIS)的抑制作用。一种新合成的衍生物表现出非常强的活性,抑制浓度值达到一半(IC 50)65 pM。使用手性HPLC从外消旋物进一步拆分出三个DHPM,并使用圆二色谱法确定了绝对构型。生物学评估表明,大多数针对NIS的活性都存在于一种对映异构体中。这项研究为抗甲状腺药物的开发以及旨在研究细胞和分子水平上碘化物转运机制的新型药理学工具的合成提供了新见识。
