Thioester and selenoester generators, thioester and selenoester compounds, and related methods for their production are provided. The subject thioester and selenoester generators include an amino acid synthon having an N-terminal group joined to a C-terminal group through an organic backbone comprising one or more carbons. The organic backbone contains a carbon having a side chain anchored to a support through a nucleophile-stable linker and is lacking reactive functional groups. The organic backbone may include a target molecule of interest, such as an amino acid, peptide, polypeptide or other organic compound of interest, and/or the N- and/or C-termini can be elaborated using a variety of synthesis approaches to provide a target molecule of interest. The compounds and methods find a wide variety of uses, including use in thioester- or selenoester-based chemical ligation techniques.
本发明提供了硫酯和硒酯生成物、硫酯和硒酯化合物及其相关生产方法。硫代酯类和硒代酯类生成物包括一种氨基酸合体,其 N 端基团通过由一个或多个碳组成的有机骨架与 C 端基团相连。有机骨架包含的碳具有侧链,通过亲核稳定连接体锚定到支持物上,并且缺乏活性官能团。有机骨架可包括感兴趣的目标分子,如氨基酸、肽、多肽或其他感兴趣的有机化合物,和/或N-和/或C-末端可使用各种合成方法进行阐述,以提供感兴趣的目标分子。这些化合物和方法用途广泛,包括用于基于硫酯或硒酯的化学连接技术。
