A series of 5,6-disubstituted pyridine-2,3-dione-3-thiosemicarbazone derivatives(2a-2n) and 5,6-disubstituted pyridine-2,3-dione S-benzyl-3-thiosemicarbazones(3a-3g) were synthesized starting from 2,3-dihydroxypyridine via oxidation-Michael additions, condensations and nucleophilic substitutions. The structures of the compounds were established by IR, 1H NMR, 13C NMR, and HRMS. All newly synthesized
一系列5,6-二取代吡啶-2,3-二酮-3-硫代半碳巴唑酮衍生物(2a-2n)和5,6-二取代吡啶-2,3-二酮S-苄基-3-硫代半碳唑酮(3a-3g)由2,3-二羟基吡啶经氧化-迈克尔加成,缩合和亲核取代而合成。化合物的结构通过IR,1 H NMR,13建立。1 H NMR和HRMS。筛选所有新合成的化合物对乳腺癌(MCF-7),结肠癌(HCT-116)和肝细胞癌(BEL7402)细胞的抗癌活性。生物测定结果表明,大多数制备的化合物在体外均表现出对各种癌细胞的细胞毒性。一些化合物表现出有希望的抗增殖活性,与阳性对照(5-氟尿嘧啶)相当。讨论了构效关系。
