The present invention relates to unnatural amino acids comprising a cyclooctynyl or trans-cyclooctenyl analog group and having formula (I) or an acid or base addition salt thereof. The invention also relates to the use of said unnatural amino acids, kits and processes for preparation of polypeptides that comprise one or more than one cyclooctynyl or trans-cyclooctenyl analog group. These polypeptides can be covalently modified by in vitro or in vivo reaction with compounds comprising an azide, nitrile oxide, nitrone, diazocarbonyl or 1,2,4,5-tetrazine group.
本发明涉及含有环辛炔基或反式环辛烯基类似物基团的非天然氨基酸,其具有化学式(I)或其酸或碱加合物。该发明还涉及所述非天然氨基酸的使用,用于制备包含一个或多个环辛炔基或反式环辛烯基类似物基团的多肽的工具和过程。这些多肽可以通过体外或体内反应与含有偶氮酰基、腈氧化物、亚硝基、偶氮甲酰基或1,2,4,5-四唑基团的化合物进行共价修饰。
