• Design and preparation of serine–threonine protein phosphatase inhibitors based upon the nodularin and microcystin toxin structures: Part 2.1 Synthesis of a functionalised nodularin macrocycle and a stripped-down microcystin macrocycle
  作者：Antony B. Maude、Amit P. Mehrotra、David Gani

  DOI：10.1039/a702410j

  日期：——

  Nodularins and microcystins are complex natural isopeptidic hepatotoxins that serve as subnanomolar inhibitors of the eukaryotic serine–threonine protein phosphatases, PP1 and PP2A. In Part 1 (A. P. Mehrotra, K. L. Webster and D. Gani, J. Chem. Soc., Perkin Trans. 1, 1997, preceding paper) each of the key structural or potentially reactive motifs within each macrocycle type was assessed as a contributor towards phosphatase inhibitory efficacy and a stripped-down nodularin-type macrocycle was identified as a suitable precursor to potentially active synthetic inhibitors. Subsequently, synthetic routes to the 19-membered nodularin macrocyclic system were developed, using solution-phase chemistry, which demonstrated that only certain cyclisation protocols were viable. Here we describe an extension of this chemistry to provide a 19-membered nodularin macrocycle, cyclo-[(3R)-3-hydroxymethyl-β-Ala-( R)-Glu-α-OMe-γ-Sar-(R)-Asp- α-OMe-β-(S)-Phe-], appropriately functionalised with a hydroxymethyl group for the incorporation of lipophilic side-chains. We also demonstrate that the 25-membered microcystin macrocycle, cyclo-[β-Ala-(R)-Glu-α- OMe-γ-Sar-(R)-Ala-(S)-Leu-( R)-Asp-α-OMe-β-(S)- Phe-], can be prepared in good yield using similar protocols in which macrocyclisation is effected through the reaction of the amino group of the (2S)-phenylalanine residue with the β-pentafluorophenyl ester of the (2R)-aspartic acid residue.

  结节素和微囊藻毒素是复杂的天然同型肽肝毒素，作为真核丝氨酸-苏氨酸蛋白磷酸酶PP1和PP2A的亚纳摩尔抑制剂。在第一部分（A. P. Mehrotra, K. L. Webster和D. Gani，《化学学会杂志》，珀金斯1号，1997年，前面的论文）中，评估了每种大环类型中每个关键结构或潜在反应性基序对磷酸酶抑制效力的贡献，并确定了一个简化版的结节素型大环作为潜在活性合成抑制剂的合适前体。随后，开发了使用溶液相化学合成19元结节素大环体系的合成路线，这表明只有某些环化方案是可行的。在这里，我们描述了这种化学方法的扩展，以提供一个19元结节素大环，环状-[(3R)-3-羟甲基-β-Ala-(R)-Glu-α-OMe-γ-Sar-(R)-Asp-α-OMe-β-(S)-Phe-]，适当地带有羟甲基团以纳入亲脂性侧链。我们还证明了25元微囊藻毒素大环，环状-[β-Ala-(R)-Glu-α-OMe-γ-Sar-(R)-Ala-(S)-Leu-(R)-Asp-α-OMe-β-(S)-Phe-]，可以使用类似的方案以良好产率制备，其中大环化是通过(2S)-苯丙氨酸残基的氨基与(2R)-天冬氨酸残基的β-五氟苯酯的反应实现的。

  A new series of monocyclic pseudopeptide tachykinin NK-2 receptor antagonists has been derived from the lead compound MEN11558. A synthesis for these molecules sharing the same intermediate was designed and performed. The replacement of the succinic moiety with an aspartic acid and the functionalization of its amino group with a wide variety of substituents led to very potent and selective NK-2 antagonists

  从先导化合物MEN11558衍生出一系列新的单环假肽速激肽NK-2受体拮抗剂。设计和执行了这些分子共享相同中间体的合成。用天冬氨酸替换琥珀酸部分，并用多种取代基对其氨基进行官能化，产生了非常有效和选择性的NK-2拮抗剂。最好的结果是通过在R的12位氨基酸上插入一个短间隔基与饱和氮杂环（​​吗啉，哌啶或哌嗪）相连而获得的。该研究产生了化合物54和57，它们在支气管收缩动物模型中以非常低的剂量具有很高的体内效力，并且作用时间长。

  D-heteroarylglycine was preferable at this position. Among synthesized cyclic pentapeptides, compound 36 (BQ-518) was the most potent ETA receptor antagonist, with a pA2 of 8.1 against ET-1-induced vasoconstriction in isolated porcine coronary arteries. This compound also showed the greatest selectivity between ETA and ETB receptors (IC50 for human ETA = 1.2 nM, IC50 for human ETB = 55 microM). In contrast, compound

  天然产物内皮素A（ETA）受体拮抗剂的类似物环（-D-Trp1-D-Glu2-Ala3-D-Val4-Leu5-）（1）和环（-D-Trp1-D-Glu2-Ala3-D -alloIle4-Leu5-）（2）的制备和测试对[125I]内皮素（ET-1）与蛋白质ETA受体结合的抑制活性。天然产物的DDLDL手性序列似乎对于抑制活性至关重要，因为D-Trp或D-Glu（或两者）在1中转化为相应的L-异构体消除了该特性。在天然产物的每个位置上的系统修饰阐明了结构-活性关系，并导致了高效和选择性的ETA受体拮抗剂。D-Trp1和Leu5多数被其他氨基酸替代导致抑制活性的显着降低。相反，用D-Asp2替代D-Glu2增强了活性。关于Ala3的位置，所有具有亚氨基酸的类似物，无论是环状的还是无环的，都比氨基酸类似物具有更高的亲和力。另外，大多数在其侧链中具有各种官能团的氨基酸替代物并未显着改变ETA结合亲和力。D-Val4
