The present invention provides modified cycloalkyne compounds; and method of use of such compounds in modifying biomolecules. The present invention features a cycloaddition reaction that can be carried out under physiological conditions. In general, the invention involves reacting a modified cycloalkyne with an azide moiety on a target biomolecule, generating a covalently modified biomolecule. The selectivity of the reaction and its compatibility with aqueous environments provide for its application in vivo (e.g., on the cell surface or intracellularly) and in vitro (e.g., synthesis of peptides and other polymers, production of modified (e.g., labeled) amino acids).
本发明提供了改性的环烷炔化合物;以及使用这些化合物在修饰生物分子方面的方法。本发明特点是可以在生理条件下进行环加成反应。通常,本发明涉及将改性的环烷炔与目标生物分子上的偶氮基团反应,生成共价修饰的生物分子。该反应的选择性及其与水性环境的兼容性使其适用于体内(例如,细胞表面或细胞内)和体外(例如,合成肽和其他聚合物,生产改性(例如,标记)氨基酸)的应用。
