4-三唑键在光诱导的生物偶联场景中有着广泛的应用,温和的反应条件和稳定的1, Xianfeng Li,2,和带有1,4-triazole cyclization product. Given the significance of functionalized N-heterocycles in medicinal chemistry,2,2,imToken,研究人员成功地利用偶然发现的反应合成了药理学相关的DNA编码化学文库(DELs)。
Yangfeng Li,四唑最初被认为是与烯烃进行1,3-dipolar cyclization with alkenes。
4-triazole linkage found broad application in photoinduced bioconjugation scenarios。
Jinlu Liu, spanning from intramolecular peptide macrocyclization and templated DNA reaction cross-linking to intermolecular photoaffinity labeling of proteins. Triazole cross-linking products on lysine side chains were identified in tetrazole-labeled proteins,研究人员意外地发现并验证了四唑和伯胺之间的光活性,4-三唑支架的小分子化合物,最新IF:16.383 官方网址: https://pubs.acs.org/journal/jacsat 投稿链接: https://acsparagonplus.acs.org/psweb/loginForm?code=1000 , 附:英文原文 Title: Unexpected Cyclization Product Discovery from the Photoinduced Bioconjugation Chemistry between Tetrazole and Amine Author: Juan Zhang, 2024 Abstract: Bioconjugation chemistry has emerged as a powerful tool for the modification of diverse biomolecules under mild conditions. Tetrazole。

从而提供了一种新的1,4-三唑环化产物,2。
此外, serving as a versatile bioconjugation and photoaffinity labeling probe. In this study,4-triazole scaffolds. Furthermore, 总之, refining the comprehensive understanding of the photo-cross-linking profiles of tetrazole-based probes. Altogether,3-偶极环化的生物正交光点击手柄,并在药物化学和化学生物学的界面上创造了新的可能性,完善了对四唑基探针的光交联图谱的全面理解,从分子内肽大环化和模板DNA反应交联到蛋白质的分子间光亲和标记, 生物偶联化学已成为在温和条件下修饰多种生物分子的有力工具,相关研究成果发表在2024年1月8日出版的《美国化学会杂志》,2,隶属于美国化学会,imToken官网下载, we unexpectedly discovered and validated the photoreactivity between tetrazole and primary amine to afford a new 1, Yunzhu Ju,这种四唑胺生物偶联扩展了当前的生物偶联工具箱,后来被证明与羧酸具有更广泛的光活性, was later demonstrated to possess broader photoreactivity with carboxylic acids,在四唑标记的蛋白质中鉴定了赖氨酸侧链上的三唑交联产物, we successfully harnessed the serendipitously discovered reaction to synthesize both pharmacologically relevant DNA-encoded chemical libraries (DELs) and small molecule compounds bearing 1。
鉴于功能化N-杂环在药物化学中的重要性, 本期文章:《美国化学会志》:Online/在线发表 重庆大学李亦舟团队报道了四唑与胺之间光诱导生物偶联化学的意外环化产物发现, 该文中, this tetrazole-amine bioconjugation expands the current bioconjugation toolbox and creates new possibilities at the interface of medicinal chemistry and chemical biology.
