摘要: 用固相法合成了首次从油菜花粉中提取的十二肽。为进一步研究其结构与活性的关系,设计并合成了它的7个肽片段和5个类似物。并通过FTIR和CD谱的测定与分析,初步讨论了它们在固体状态和不同溶剂中的结构问题。同时,用肿瘤坏死因子TNF实验、T-淋巴细胞转化实验和E-玫瑰花结实验测定了它们的生理活性。结果提示该十二肽和它的某些片段具有增强TNF抗肿瘤细胞和在体外能促进猪胸腺细胞成熟的作用。

Abstract: We have prepared a dodecapeptide, which was first extracted from Chinese rape pollen, by using solid-phase synthesis method.In order to study its structure function relation, seven peptide segments and five analogues were designed and synthesized. We have initially discussed their structures in solid state and different solvents using FTIRand CDspectra. In addition, their immunopromotive activies have been observed by E-rosette test, tumor necrosis factor(TNF) test and T-lymphocyte transformation test in vitro. The observed results show the dodecapeptide and some segments can cause the maturation of pig thymocyte in vitro and enhance the activity of TNF on murine tumor cells.
