An Fmoc Compatible, O to S Shift-Mediated Procedure for the Preparation of C-Terminal Thioester Peptides
摘要:
We report a practical 2-hydroxy-3-mercapto-propionic acid (Hmp)/2-methylpiperidine (2-MP) based Fmoc chemistry procedure to prepare the C-terminal limp peptides, which serve as the precursors of C-terminal thioester peptides. The subsequent O to S acyl shift and thiol-exchange mediated thioester conversion of the crude precursor peptides can be accomplished smoothly under mild conditions to provide the desired thioester peptides with good yield and high quality. This is a highly adaptable approach, and we envision its broad application in the preparation of C-terminal thioester peptides.

death by concomitant blockage of constitutive and immunoproteasomes. In contrast, selectiveimmunoproteasomeinhibition is less cytotoxic and has the potential to modulate chronic inflammation and autoimmune diseases. In this study, we rationally designed decarboxylated peptides that covalently target a non‐catalyticcysteine of the immunoproteasome subunit β5i with α‐chloroacetamide‐containing sidechains
