Polyfunctional tetrahydro-2H-pyrano[3,2-c]pyridazin-3(6H)-one derivatives were synthesized and biologically evaluated as novel anticancer agents. These motifs were produced by a five-step reaction sequence in which the Achmatowicz oxidative cyclization, is the basic core for such synthesis. Compounds 15f, 16c, and 16d showed antiproliferative activity against the SK-BR-3 breast cancer cell line. Importantly
合成了多官能的四氢-2H-吡喃并[3,2-c]哒嗪-3(6H)-一衍生物,并将其作为新型抗癌剂进行了生物学评估。这些基序是通过五步反应序列产生的,其中Achmatowicz氧化环化是此类合成的基本核心。化合物15f,16c和16d显示出对SK-BR-3乳腺癌细胞系的抗增殖活性。重要的是,16c和16d表现出最高的功效,与其他测试的癌细胞系相比,抗SK-BR-3的效力高约30倍(分别为IC 50 0.21和0.15μM)。此外,16c和16d与SK-BR-3乳腺癌细胞相比,对正常乳腺癌细胞MCF10A的毒性降低了约295倍。这些化合物为我们继续努力开发有效的抗癌药物奠定了进一步研究的基础。
