本期文章:《科学》:Volume 391 Issue 6785 苏黎世联邦理工学院Jeffrey W. Bode团队的最新研究提出了两性离子有机硼配合物克服化学蛋白质合成中的浓度屏障, restricting access to poorly soluble proteins. Potassium acyltrifluoroboronates (KATs) offer a promising alternative through fast and chemoselective amide bond formation, but their application to protein synthesis has been precluded by the lack of a masking strategy. We report chiral,。

These molecules exhibit unexpected nitrogen-carbon-boron connectivity and are fully compatible with solid-phase peptide synthesis and stereoretentive deprotection. We synthesized C-terminal KAT peptides and demonstrated KAT ligation at micromolar concentrations for the convergent synthesis of the aggregation-prone programmed death ligand 2 (PD-L2) immunoglobulin V domain. This work establishes organoboron chemistry as an enabling strategy for chemical protein synthesis at low concentrations far more suitable for handling large,它们在蛋白质合成中的应用一直受到阻碍, Jeffrey W.
