Disclosed herein are non-natural amino acids and polypeptides that include at least one non-natural amino acid, and methods for making such non-natural amino acids and polypeptides. The non-natural amino acids, by themselves or as a part of a polypeptide, can include a wide range of possible functionalities, but typical have at least one heterocycle, aldol-based, dicarbonyl, and/or diamine group. Also disclosed herein are non-natural amino acid polypeptides that are further modified post-translationally, methods for effecting such modifications, and methods for purifying such polypeptides. Typically, the modified non-natural amino acid polypeptides include at least one heterocycle, aldol-based, dicarbonyl, and/or diamine group. Further disclosed are methods for using such non-natural amino acid polypeptides and modified non-natural amino acid polypeptides, including therapeutic, diagnostic, and other biotechnology uses.
本文披露了非天然氨基酸和多肽,其中包括至少一个非天然氨基酸,以及制备这种非天然氨基酸和多肽的方法。这些非天然氨基酸本身或作为多肽的一部分,可以包括各种可能的功能,但通常至少具有一个杂环,醛缩基,二羰基和/或二胺基团。本文还披露了经翻译后进一步修饰的非天然氨基酸多肽,以及实现这种修饰的方法和纯化这种多肽的方法。通常,修饰后的非天然氨基酸多肽包括至少一个杂环,醛缩基,二羰基和/或二胺基团。此外,还披露了使用这种非天然氨基酸多肽和经修饰的非天然氨基酸多肽的方法,包括治疗,诊断和其他生物技术用途。
