  • Cyclopropane-Derived Peptidomimetics. Design, Synthesis, and Evaluation of Novel Enkephalin Analogues
    作者:Stephen F. Martin、Michael P. Dwyer、Benoît Hartmann、Kyle S. Knight
    DOI:10.1021/jo991288h
    日期:2000.3.1
    lactones with dipeptides, and a novel method for the synthesis of substituted diaminocyclopropanes was also developed. The Leu-enkephalin analogues were tested in a panel of binding and functional assays, and although those derivatives containing cyclopropane replacements of the Gly(2)-Gly(3) exhibited low micromolar affinity for the mu-receptor, analogues containing such replacements for the Phe(4)-Leu(5)
    已知含有反式取代的环丙烷的肽模拟物可稳定寡肽的延伸构象,并且分子模型研究现在表明,相应的顺式环丙烷二肽等排体可以稳定反向。为了开始评估这种可能性,在亮氨酸脑啡肽(H(2))中引入了一系列顺式取代的环丙烷作为Gly(2)-Gly(3)和Phe(4)-Leu(5)二肽亚基的替代物N-Tyr-Gly-Gly-Phe-Leu-OH),据信以含有β-转角的构象结合阿片受体。通过具有手性铑配合物Rh(2)催化的烯丙基重氮乙酸酯对映选择性环化的序列,开发了合成含环丙烷的二肽等排体-XaaPsi [COcpCO] Yaa-和-XaaPsi [NHcpNH] Yaa-的一般方法。 [(5S)-MEPY](4)和Rh(2)[(5R)-MEPY](4)。将Weinreb酰胺化方法的有用的修饰应用于用二肽打开内酯中间体,并且还开发了合成取代的二氨基环丙烷的新方法。在结合和功能测定小组中测试了亮氨酸脑啡肽类似物,尽
  • Total Synthesis and Structure Revision of Didemnaketal B
    作者:Haruhiko Fuwa、Takashi Muto、Kumiko Sekine、Makoto Sasaki
    DOI:10.1002/chem.201303713
    日期:2014.2.10
    Didemnaketal B, a structurally complex spiroacetal that exhibits potent HIV‐1 protease inhibitory activity, was originally discovered by Faulkner and his colleagues from the ascidian Didemnum sp. collected at Palau. Its absolute configuration was proposed on the basis of degradation/derivatization experiments of the authentic sample. However, our total synthesis of the proposed structure of didemnaketal B
    Didemnaketal B是一种结构复杂的螺缩醛,具有强大的HIV-1蛋白酶抑制活性,最初是由Faulkner及其同事从Didemnum sp。中发现的。在帕劳收集。根据真实样品的降解/衍生化实验,提出了其绝对构型。但是,我们对拟南芥B结构的总合成对Faulkner等人的立体化学分配提出了质疑。在这里,我们详细描述了拟南芥B拟议结构2的第一个全合成,其特征为1)通过利用Suzuki-Miyaura偶联的策略收敛合成C7-C21螺缩醛结构域,2)Evans syn-C1–C7无环结构域的组装的醛醇缩合反应和乙烯基Mukaiyama醛醇缩合反应,以及3)构造C21–C28侧链结构域的Nozaki–Hiyama–Kishi反应。合成2和真实样品之间观察到的NMR光谱差异以及对福克纳立体化学赋值的仔细检查使我们推测2的C10–C20结构域的绝对构型已被错误赋值。因此,实现了修饰结构65的全合成,

  • Aplyronine A, a Potent Antitumor Substance of Marine Origin, Aplyronines B and C, and Artificial Analogues:  Total Synthesis and Structure−Cytotoxicity Relationships
    作者:Hideo Kigoshi、Kiyotake Suenaga、Tsuyoshi Mutou、Takeshi Ishigaki、Toshiyuki Atsumi、Hiroyuki Ishiwata、Akira Sakakura、Takeshi Ogawa、Makoto Ojika、Kiyoyuki Yamada
    DOI:10.1021/jo9606113
    日期:1996.1.1
    The enantioselective total synthesis of aplyronine A (1), a potent antitumor substance of marine origin, was achieved by a convergent-approach Three segments 4, 5, and 6, corresponding to the C5-C11, C21-C27, and C28-C34 portions of aplyronine A (1), were prepared using:the Evans aldol reaction and the Sharpless epoxidation as key steps. The coupling reaction of 4 with iodide 7 followed by julia olefination with sulfone 8 gave the C5-C20 segment 9, while the julia coupling reaction between segments 5 and 6 provided the C21-C34 segment 10. Julia olefination between segments 9 and 10 and the subsequent four-carbon homologation reaction led to seco acid 83, which was converted into aplyronine A (1) by Yamaguchi lactonization followed by the introduction of two amino acids. The use of the [(3,4-dimethoxybenzyl)oxy]methyl group as a protecting group for the hydroxyl at C29 was crucial for this synthesis. The enantioselective synthesis of two natural congeners, aplyronines B (2) acid C (3), was also carried out using the intermediates for the synthesis of 1, which determined the absolute stereostructures of 2 and 3 unambiguously. To study the structure-cytotoxicity relationships of aplyronines, artificial analogues of 1 were synthesized and their cytotoxicities were evaluated: the trimethylserine moiety, two hydroxyl groups, and the side-chain portion in 1 turned out to be important in the potent cytotoxicity shown by 1. Biological studies with aplyronine A (1) showed that 1 inhibited polymerization of G-actin to F-actin and depolymerized F-actin to G-actin.
