    Glycosylated Antitumor Ether Lipids (GAELs) kill cancer cells by a nonapoptotic pathway which is an attractive strategy to avoid resistance. To further optimize the antitumor effect, we prepared various analogs of di-, and tri-cationic GAEL analogs differing in the nature of the sugar (D-giucose or L-glucose), the anomeric linkage as well as position of the glycerolipid moiety. The di- and tri-cationic GAELs were synthesized and their in vitro anticancer properties were evaluated against drug resistant and aggressively growing cancer cell lines derived from human breast, prostate, pancreatic and ovarian cancers. The most potent dicationic GAEL analogs were also studied against cancer stem cells obtained from breast BT 474, prostate DU145 and ovarian A2780cp cell lines. Our results indicate that the number of positive charges, the position of the amino substituents and the nature of the sugar have significant effects on the anticancer activities of these compounds. The most active analog kill 50% of the cells at concentration range of 0.5-5μΜ and 90% of the cells at the concentration of 1-10μΜ depending on type of cancer cells.
    糖基化抗肿瘤醚脂质(GAELs)通过一种非凋亡途径杀灭癌细胞,这是一种吸引人的策略,可以避免抗药性。为了进一步优化抗肿瘤效果,我们制备了不同的双-和三-阳离子GAEL类似物,其糖的性质(D-葡萄糖或L-葡萄糖)、缩醛键以及甘油脂类团的位置不同。合成了双-和三-阳离子GAEL类似物,并评估了它们对人类乳腺、前列腺、胰腺和卵巢癌衍生的耐药和快速生长的癌细胞系的体外抗癌性能。最有效的双阳离子GAEL类似物也针对从乳腺BT 474、前列腺DU145和卵巢A2780cp细胞系中获得的癌干细胞进行了研究。我们的结果表明,阳离子数量、氨基取代物的位置和糖的性质对这些化合物的抗癌活性有显著影响。最活跃的类似物在浓度范围为0.5-5μΜ时杀死50%的细胞,在浓度为1-10μΜ时杀死90%的细胞,具体取决于癌细胞类型。

  • Catalysis-Based Total Synthesis of Putative Mandelalide A
    作者:Jens Willwacher、Alois Fürstner
    DOI:10.1002/anie.201400605
    日期:2014.4.14
    A concise synthesis of the putative structure assigned to the highly cytotoxic marine macrolide mandelalide A (1) is disclosed. Specifically, an iridium‐catalyzed two‐directional Krische allylation and a cobalt‐catalyzed carbonylative epoxide opening served as convenient entry points for the preparation of the major building blocks. The final stages feature the first implementation of terminal‐acetylene
    公开了推测的结构的简明合成,所述假定的结构分配给具有高细胞毒性的海洋大环内酯扁桃内酯A(1)。特别是,铱催化的双向Krische烯丙基化反应和钴催化的羰基化环氧化物开口是制备主要结构单元的便捷入口。最后阶段的特征是将末端乙炔复分解首次应用于天然产物合成中,这是非常了不起的,因为这类底物直到最近才得以实现。成功的关键是使用高选择性钼亚烷基络合物42作为催化剂。尽管合成样品的组成和立体化学是明确的,但1以及11-的光谱epi - 1不同于天然产物,这意味着在原始结构分配中存在细微但根深蒂固的错误。
