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

biological activity. Up to date, thiazolopyrimidines derivatives have widespread applications in pharmaceutical fields. In this article, a series of thiazolopyrimidine derivatives were designed based on the lead compound structure in our previous studies. Methods: All the target compounds were synthesized with the coupling reaction, Biginelli reaction and “one-pot” aldol condensation. Their structures
背景:噻唑并嘧啶具有其结构多样性和多种生物学活性。迄今为止,噻唑并嘧啶衍生物已在制药领域中广泛应用。在本文中,我们在先前的研究中基于铅化合物的结构设计了一系列噻唑并嘧啶衍生物。 方法:通过偶联反应,Biginelli反应和“一锅法”羟醛缩合反应合成所有目标化合物。它们的结构通过1 H NMR,13 C NMR光谱和HRMS鉴定。通过MTT评估目标化合物的抗肿瘤活性。 结果:合成了25种新的目标化合物,主要是通过测试它们对两种人类肿瘤细胞系的抑制率进行筛选,化合物15、17、20、22、40对MDA-MB-231和K562的抑制率均超过70% 。进一步评估它们针对五种肿瘤细胞系的IC50,15和22在MDAMB-231,K562和PC-3中显示出优于先导化合物I的优势。 结论:合成了一系列噻唑并嘧啶衍生物,初步的生物学评估表明,目标化合物22对棉铃虫K562的抗增殖活性优于棉酚。
