  • Total Synthesis of the Cyclodepsipeptide Apratoxin A and Its Analogues and Assessment of Their Biological Activities
    作者:Dawei Ma、Bin Zou、Guorong Cai、Xiaoyi Hu、Jun O. Liu
    DOI:10.1002/chem.200600599
    日期:2006.10.5
    A novel total synthesis of apratoxin A is described, with key steps including the assembly of its ketide segment through a D-proline-catalyzed direct aldol reaction and Oppolzer's anti aldol reaction and the preparation of its thiazoline unit in a biomimetic synthesis. An oxazoline analogue of apratoxin A has also been elaborated by a similar approach. This compound has a potency against HeLa cell
    描述了一种新颖的全合成Apratoxin A,其关键步骤包括通过D-脯氨酸催化的直接羟醛反应和Oppolzer的抗羟醛反应组装其化物片段,并在仿生合成中制备其噻唑啉单元。甲毒素A的恶唑啉类似物也已通过类似的方法进行了精心设计。该化合物具有抗HeLa细胞增殖的能力,仅略低于Apratoxin A的能力,而Aptoxin A的C(40)-去甲基化的恶唑啉类似物显示出低得多的细胞毒性,C(37)-顶基和C(37)的去甲基化该新类似物的产品无效。这些结果表明,C(37)和C(40)处的两个甲基以及C(37)处的立体化学对于Apratoxin A的恶唑啉类似物的有效细胞活性至关重要。
  • Synthesis of an Oxazoline Analogue of Apratoxin A

    日期:2003.9.1
    [structure: see text] Michael addition of Me(2)Cu(CN)Li(2) to alpha,beta-unsaturated lactone 7 derived from beta-hydroxyl ketone 5 provides lactone 8, which is converted to alcohol 11 using Oppolzer's methodology as the key step. Connection of 11 with the l-proline moiety and subsequent installation of an oxazoline ring affords 16, which is coupled with tripeptide 21; subsequent macrocyclization then
    [结构:参见正文]将Me(2)Cu(CN)Li(2)迈克尔加成自β-羟基5衍生的α,β-不饱和内7提供了内8,使用Oppolzer的方法将内8转化为醇11关键步骤。11与1-脯酸部分的连接和随后的恶唑啉环的安装得到16,其与三肽21偶联;随后进行大环化,然后得到4,一种毒素A的恶唑啉类似物。
  • Improved Total Synthesis and Biological Evaluation of Potent Apratoxin S4 Based Anticancer Agents with Differential Stability and Further Enhanced Activity
    作者:Qi-Yin Chen、Yanxia Liu、Weijing Cai、Hendrik Luesch
    DOI:10.1021/jm4019965
    日期:2014.4.10
    Apratoxins are cytotoxic natural products originally isolated from marine cyanobacteria that act by preventing cotranslational translocation early in the secretory pathway to downregulate receptor levels and inhibit growth factor secretion, leading to potent antiproliferative activity. Through rational design and total synthesis of an apratoxin A/ E hybrid, apratoxin S4 (1a), we have previously improved the antitumor activity and tolerability in vivo. Compound la and newly designed analogues apratoxins S7-S9 (1b-d), with various degrees of methylation at C34 (1b,c) or epimeric configuration at C30 (1d), were efficiently synthesized utilizing improved procedures. Optimizations have been applied to the synthesis of key intermediate aldehyde 7 and further include the application of Leighton's silanes and modifications of Kelly's methods to induce thiazoline ring formation in other crucial steps of the apratoxin synthesis. Apratoxin S9 (1d) exhibited increased activity with subnanomolar potency. Apratoxin S8 (lc) lacks the propensity to be deactivated by dehydration and showed efficacy in a human HCT116 xenograft mouse model.
