cells in vitro by the colony formation assay and in vivo. These newly synthesized derivatives show a dramatically higher chemotherapeutic activity in killing human cancer cells than the parent drug, camptothecin, and clinically available drugs, irinotecan and taxol.
用酰化法制备了一系列(20S)-喜树碱衍生物的氧链烷酸酯。通过集落形成试验和在体内评价了它们在癌细胞上的抗肿瘤活性。这些新合成的衍生物在杀死人癌细胞中显示出比母体药物喜树碱和临床上可用的药物伊立替康和紫杉醇显着更高的化学治疗活性。
