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).
本发明提供了改性环烷烃化合物;以及将此类化合物用于改性生物大分子的方法。本发明的特点是可以在生理条件下进行环化反应。一般来说,本发明包括使修饰的环烷烃与目标生物大分子上的叠氮基反应,生成共价修饰的生物大分子。该反应的选择性及其与水环境的兼容性为其在体内(如细胞表面或细胞内)和体外(如肽和其他聚合物的合成、修饰(如标记)氨基酸的生产)的应用提供了条件。
