amines, phosphonates and thiols to Tagitinin C containing in its structure an α-methylene-γ-lactone motif and two α,β-unsaturated ketone systems has been described. 27 Tagitinin C derivatives were synthesized and isolated in good to excellent yield (up to 99% yield) under mild reaction conditions. The biological activity of Tagitinin C and its derivatives were evaluated against three human cancer cell
胺、膦酸酯和硫醇与 Tagitinin C 的迈克尔加成反应在其结构中包含一个 α-亚甲基-γ-内酯基序和两个 α,β-不饱和酮系统已被描述。在温和的反应条件下,合成并分离了 27 种 Tagitinin C 衍生物,收率非常好(收率高达 99%)。Tagitinin C 及其衍生物对三种人类癌细胞系(乳腺癌人类癌细胞 MCF-7、对药物 MCF7-MDR 多重耐药的乳腺癌人类癌细胞、胰腺癌细胞 MiaPaCa-2)和正常细胞的生物活性进行了评估线(HEK-293)作为对照。我们表明 Tagitinin C 衍生物的生物活性仍然存在。这些化合物具有增强的水溶性,可以提高其生物利用度和药理学特征。
