  一种高效且经济有效的方法，利用Bryopsis pennata的滋生藻类藻华来进行Kahalalide F N末端修饰

  摘要：

  背景 可以从软体动物Elysia rufescens及其饮食藻类Bryopsis pennata分离得到的Kahalalide F（KF）及其异构体iso-kahalalide F（isoKF）是有效的细胞毒性药物，已通过五项临床试验进行了研究。由于半衰期短，活性谱窄以及患者反应中等，因此需要进一步努力修饰该分子以解决其局限性。另外，由于使用固相肽合成（SPPS）生产KF类似物的高成本，因此使用了从季节性藻华中提取天然KF的降解和重建方法来产生KF类似物。 方法 使用稀盐酸，将N保护的KF在1- Thr12和d- Val13之间的酰胺键上小心水解。C端片段的合成开始于己酸琥珀酰亚胺酯的形成，然后与二肽反应。最后的偶联反应是在半合成的Fmoc-KF水解产物和C末端片段之间进行的，然后对Fmoc基团进行脱保护。 结果 六个KF类似物，在N端链上带有一个氨基酸残基，d -Val14–isoKF

  Simplified Pepstatins:  Synthesis and Evaluation of N-Terminally Modified Analogues

  摘要：

  The promising strategy of gastric ulcer healing with perorally administered epidermal growth factor (EGF) is so far strongly limited by the pepsinic degradation of this therapeutic polypeptide in the stomach. The incorporation of EGF in a bioadhesive polymer-pepsin inhibitor conjugate used as drug carrier matrix, however, might provide sufficient protection toward pepsinic degradation. The synthesis of appropriate pepsin inhibitors represents a prerequisite for the development of such polymer-inhibitor conjugates. The presented study demonstrates that modifications at the N-terminus of simplified analogues of pepstatin which can be synthesized in a simple and straight way result only in slight variations of the inhibitory activity. These analogues display only 10-fold reduced-inhibitory activity, compared to pepstatin A, when bearing a greater N-terminal group like isovaleryl, Boc, or Cbz. Compounds which are substituted at the N-terminus by a shorter N-acyl group like propionyl or cyclopropylcarbonyl show further reduced activity (0.01, compared to pepstatin A). The presence of an amide or a urethane moiety at the N-terminus has no considerable effect on enzyme inhibition. Therefore, the N-terminus of these analogues is able to be modified forming a covalent bond to various bioadhesive polymers via a suitable functionality.

  Stereoisomers and analogues of amastatin, [(2S, 3R)-3-amino-2-hydroxy-5-methylhexanoyl]-L-Val-L-Val-L-Asp, were synthesized and their inhibitory activities towards aminopeptidase A (AP-A) and other arylamidases tested. Among the four stereoisomers of a new amino acid residue in amastatin, the 2S stereoisomers exhibited strong activity. In a series of compounds in which the C-terminal amino acid of amastatin was substituted by other amino acids, the one containing Asp or Glu showed the strongest activity towards AP-A. In a series of compounds in which the second or third residue from the amino terminal of amastatin was substituted by other amino acids, the one containing hydrophobic amino acids showed strong activity. In the study of the relationship of the length of the peptide chain and inhibitory activity, the activity towards AP-A was seen to increase until the length of the peptide reached that of a tetrapeptide.
