[00420] Disclosed herein are non-natural amino acids and dolastatin analogs that include at least one non-natural amino acid, and methods for making such non-natural amino acids and polypeptides. The dolastatin analogs can include a wide range of possible functionalities, but typically have at least one oxime, carbonyl, dicarbonyl, and/or hydroxylamine group. Also disclosed herein are non-natural amino acid dolastatin analogs that are further modified post-translationally, methods for effecting such modifications, and methods for purifying such dolastatin analogs. Typically, the modified dolastatin analogs include at least one oxime, carbonyl, dicarbonyl, and/or hydroxylamine group. Further disclosed are methods for using such non-natural amino acid dolastatin analogs and modified non-natural amino acid dolastatin analogs, including therapeutic, diagnostic, and other biotechnology uses.
本文披露了包含至少一种非天然氨基酸和多拉斯塔汀类似物的非天然氨基酸,以及制备这种非天然氨基酸和多肽的方法。多拉斯塔汀类似物可以包括各种可能的官能团,但通常至少包含一个肟、酮、二酮和/或羟胺基团。本文还披露了进一步在翻译后修饰的非天然氨基酸多拉斯塔汀类似物,以及实现这种修饰的方法和纯化这种多拉斯塔汀类似物的方法。通常,经修饰的多拉斯塔汀类似物包括至少一个肟、酮、二酮和/或羟胺基团。此外,还披露了使用这种非天然氨基酸多拉斯塔汀类似物和修饰后的非天然氨基酸多拉斯塔汀类似物的方法,包括治疗、诊断和其他生物技术用途。
