Pteridines are an important class of fused heterocycles found in natural products and drug molecules, and have shown diverse biological activities. A focused library of 5,8-dihydropteridine-6,7-dione derivatives were designed and evaluated for their antiproliferative activity against MGC-803, SGC-7901, A549 and PC-3 cancer cell lines. The SARs studies highlighted the importance of the piperazine substituted
蝶啶是在天然产物和药物分子中发现的重要一类稠合杂环,并已显示出多种生物活性。设计了5,8-二氢蝶啶-6,7-二酮衍生物的重点文库,并评估了它们对MGC-803,SGC-7901,A549和PC-3癌细胞系的抗增殖活性。SARs研究强调了哌嗪取代的5,8-二氢蝶啶-6,7-二酮构架对于活性的重要性,并揭示了必不可少的结构要素。在这些化合物中,化合物5n对测试的细胞系表现出最有效和广谱的抗增殖抑制作用,并对MGC-803细胞系敏感,效力比5-FU略强。初步的力学研究表明,化合物5n可以抑制MGC-803细胞的集落形成和迁移。此外,流式细胞仪分析表明,化合物5n浓度依赖性地诱导了MGC-803细胞的凋亡。我们的研究表明,哌嗪取代的5,8-二氢蝶啶-6,7-二酮骨架可被视为设计针对胃癌细胞的有效抗肿瘤药物的新化学型。
