  First Total Synthesis of Leucamide A

  摘要：

  The first total synthesis of marine bioactive cyclic heptapeptide Leucamide A has been accomplished, including a simple method for construction of the 4,2-bisheterocycle tandem pair substructure that employs a DAST-mediated cyclization of beta-hydroxy amide and final HBTU-promoted ring closing.

  The present invention provides small molecule compounds of bisheterocycle in tandem having the structural formula of P1-P2, and the use thereof as well as a composition containing the compounds, each of P1 and P2 is an unsaturated 5-member heterocyclic ring having one or two heteroatoms. This compound may effectively inhibit the replication of influenza virus, the DNA replication of hepatitis B virus (HBV), and the formation of HBsAg and HBeAg. These compounds can be used for the preparation of a medicament for viral diseases, and may overcome the limitations of the known nucleosides drugs, including cytotoxicity, the requirement of other drugs having different structures for against the drug-resistant virus variants induced by long-term therapy. The structure of the compounds according to the invention is relatively simple and easy to be prepared.

  In order to study the effect of heterocyclic core conformational state of leucamide A on its anti-influenza virus A activity, five conformational analogues were prepared by replacing the Pro-Leu dipeptide in the molecule with various amino acids. The amino acids used were of 2 to 6 carbons. The results showed that these replacements not only changed the conformational relationship between the 4,2-bisheterocycle tandem pair and the third heterocycle, but also had dramatic effect on its activity against influenza virus A.

  为了研究白酰胺 A 的杂环核心构象状态对其抗甲型流感病毒活性的影响，我们用不同的氨基酸取代了分子中的 Pro-Leu 二肽，制备了五种构象类似物。所使用的氨基酸含有 2 至 6 个碳原子。结果表明，这些替换不仅改变了 4,2-二杂环串联对和第三个杂环之间的构象关系，而且对其抗甲型流感病毒的活性产生了巨大影响。
