This invention relates to prostate-specific membrane antigen (PSMA) antibodies and antibody drug conjugates comprising at least one non-naturally-encoded amino acid. Disclosed herein are αPSMA antibodies with one or more non-naturally encoded amino acids and further disclosed are antibody drug conjugates wherein the αPSMA antibodies of the invention are conjugated to one or more toxins. 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 antibody drug conjugates, dolastatin analogs, and modified non-natural amino acid dolastatin analogs, including therapeutic, diagnostic, and other biotechnology uses.
本发明涉及前列腺特异性膜抗原(PSMA)抗体及包含至少一个非天然编码氨基酸的抗体药物偶联物。公开了具有一个或多个非天然编码氨基酸的αPSMA抗体,以及进一步公开了抗体药物偶联物,其中本发明的αPSMA抗体与一个或多个毒素偶联。还公开了非天然氨基酸多拉司汀类似物,这些类似物在翻译后进一步修饰,以及实现这些修饰的方法和纯化这些多拉司汀类似物的方法。通常,修饰的多拉司汀类似物包括至少一个肟、羰基、二羰基和/或羟基胺基团。进一步公开了使用此类非天然氨基酸抗体药物偶联物、多拉司汀类似物和修饰的非天然氨基酸多拉司汀类似物的方法,包括治疗、诊断和其他生物技术用途。
