gold-catalyzed glycosylation with S-but-3-ynyl thioglycoside donors was employed for the synthesis of analogues (6 and 7) bearing disaccharide subunits containing α-l-olivoside and α-l-olioside moiety, respectively. Aquayamycin (3), analogues (4-7), and our previously synthesized derhodinosylurdamycin A (2) were then submitted to the Development Therapeutics Program of the National Cancer Institute of National
合成了
水霉素(3)和许多带有不同2-脱氧糖亚基(4-7)的安古环素抗肿瘤抗生素derhodinosylurdamycin A的类似物。这些分子(3-7)是基于先前报道的由我们小组报道的合成derhodinosylurdamycin A(2)的聚合策略合成的。特别是,我们最近开发的具有S-but-3-ynyl巯基糖苷供体的轻度阳离子
金催化的糖基化被用于合成带有含α-1-
寡糖苷和α-1-
寡糖苷部分的二糖亚基的类似物(6和7)。 , 分别。
阿卡霉素(3),类似物(4-7),然后将我们先前合成的derhodinosylurdamycin A(2)提交给美国国立卫生研究院国家癌症研究所的开发治疗计划,以使用标准方案对NCI-60人肿瘤细胞株进行筛选。结果发现,带有糖亚基的derhodinosylurdamycin A(2),aquayamycin(3)和其他三个类似物(5-7)对这些癌
