通过将电化学氧化脱羧与串联水解/还原途径配对,以一种有效且无差向异构化的方法获得设计者 C 末端肽酰胺。类似于 Nature 对生物活性伯 α-酰胺的双重酶促方法,该方法提供具有高价值功能基序的仲和叔酰胺,包括同位素标记和用于生物偶联的手柄。该协议利用了 C 末端羧酸盐的固有反应性,与绝大多数蛋白质功能组兼容,并且在没有差向异构化的情况下进行,从而解决了与传统基于耦合的方法相关的主要限制。该方法的实用性通过合成天然产物 acidiphilamide A来举例说明关键的非对映选择性还原,以及生物活性肽和相关类似物,包括抗 HIV 先导肽和重磅炸弹癌症治疗剂亮丙瑞林。

The present invention relates to methods for identifying compounds capable of modulating a cellular response. The methods involve attaching living cells to solid supports comprising a library of test compounds. The test compounds are linked to the solid support via cleavable linkers and may thus be released from the solid supports. Solid supports comprising cells, wherein the cellular response of interest has been modulated are selected and the test compound of the solid support can then be identified. The cellular response may for example be changes in complex formation between proteins.
