一种含光亲和标记异戊烯侧链探针的合成与初步表征

Synthesis and Activity of the Photoaffinity-Labeled Functional Probe Based on Prenyl Side-Chain

经5步反应、以9%的总收率合成了一种含生物素修饰和光亲和标记的异戊烯侧链功能探针分子,初步考察了反应条件下该探针分子与Saccharomyces cerevisiae AS 2.399粗蛋白的相互作用;生物素印迹分析结果表明,酵母中多种蛋白被探针分子修饰,为进一步开展化学蛋白组学研究奠定了基础.

A novel functional probe bearing both a benzophenone moiety and a biotin moiety was synthesized in 5 steps with an overall yield of 9%. Photoaffinity labeling and biotin blot experiment with the probe and the crude protein extracts from Saccharomyces cerevisiae AS 2.399 revealed that the synthetic probe was attached to a number of proteins, providing a basis for further chemical proteomics research.
