Summary: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 use. L'invention concerne des acides aminés non naturels et des analogues de dolastatine comprenant au moins un acide aminé non naturel, et des procédés permettant d'élaborer de tels acides aminés et des polypeptides. Les analogues de dolastatine peuvent comprendre une large gamme de fonctionnalités possibles, mais typiquement, ils ont au moins un groupe oxyme, carbonyle, dicarbonyle et/ou hydroxylamine. En outre, l'invention concerne des analogues de dolastatine comprenant des acides aminés non naturels qui sont modifiés ultérieurement après traduction; des procédés permettant d'effectuer de telles modifications et des procédés pour purifier ces analogues de dolastatine. Typiquement, les analogues de dolastatine modifiés comprennent au moins un groupe oxyme, carbonyle, dicarbonyle et/ou hydroxylamine. En outre, l'invention concerne des procédés pour utiliser de tels analogues de dolastatine comprenant des acides aminés non naturels et de tels analogues de dolastatine comprenant des acides aminés non naturels modifiés, y compris une utilisation thérapeutique, diagnostique et également une utilisation en biotechnologie.
