  Synthesis of the All-l Cyclopentapeptides Versicoloritides A, B, and C

  摘要：

  Herein we describe the first synthesis of the all-L naturally occurring cyclopentapeptides versicoloritides A, B, and C. We found that the extent of oligomerization and epimerization upon head-to-tail cyclization of the linear pentapeptide precursors could be reduced to acceptable levels by modifying the reaction conditions.

  Antifreeze glycoproteins (AFGPs) are glycosylated polypeptides produced by Antarctic and Arctic fishes, which allow them to survive in seawater at sub-zero temperatures. An investigation into the postulated enteric uptake of AFGP synthesized in the exocrine pancreas of Antarctic fishes required a custom-prepared AFGP probe that incorporated seven isotopically-labelled Ala residues for detection by

  抗冻糖蛋白（AFGP）是南极和北极鱼类产生的糖基化多肽，可以使它们在低于零温度的海水中生存。对南极鱼类外分泌胰腺中合成的AFGP的假定肠摄取的调查，需要定制的AFGP探针，该探针结合了7个同位素标记的Ala残基，用于质谱检测。的AFGPs由重复的三个氨基酸单元（丙氨酸-丙氨酸-苏氨酸），其中，所述苏氨酸残基是糖基化与二糖的β- d -Gal-（1→3）-α- d -GalNAc。同位素标记的AFGP8（1）的合成，以及受保护的糖基化氨基酸构件2的优化合成，已报告。

  The first synthesis and osteoblast proliferative activity of the naturally occurring cyclic peptides dianthins G and H is described. The greater potency of naturally occurring dianthin G over dianthin H at physiological concentrations mirrored the osteoblast proliferative activity observed for synthetic dianthins G and H. Six alanine-scan analogues of the more potent dianthin G were also synthesised and osteoblast assays revealed that four of the six residues can be further modified for improved activity. We also confirmed by variable temperature H-1 NMR spectroscopic analysis that the sets of major and minor signals observed for dianthins G and H in DMSO-d(6) are in fact due to cis-trans rotational isomers of the praline ring.
