The synthesis of celastrol analogues containing amino acid ester at the C(29) position and their evaluation for cytotoxic activities in vitro were reported. The MTT test showed that a set of derivatives with lower IC50 values than that of the positive control group cisplatin and the parent compound celastrol, which exhibited greater antiproliferative activities. The most potent title compounds 2a and
报道了在 C(29) 位置含有氨基酸酯的 Celastrol 类似物的合成及其对体外细胞毒活性的评价。MTT试验表明,一组衍生物的IC50值低于阳性对照组顺铂和母体化合物celastrol,表现出更大的抗增殖活性。最有效的标题化合物 2a 和 2e 在体外对 HeLa 和 A549 细胞系表现出细胞毒活性,IC50 值分别为 0.371 和 0.237 μm、0.235 和 0.109 μm。细胞凋亡实验表明2a和2e可以在低浓度下诱导A549细胞凋亡。这些结果表明,2a 和 2e 可能有希望作为抗肿瘤剂进行进一步研究。
