Abstract
Chemical synthesis of proteins with aggregable or colloidal peptide segments presents a formidable task, as such peptides prove to be difficult for both solid-phase peptide synthesis and peptide ligation. To address this issue, we have developed ligation embedding aggregation disruptor (LEAD) as an effective strategy for the chemical synthesis of difficult-to-obtain proteins. The N,O/S-benzylidene acetals generated from Ser/Thr ligation and Cys/Pen ligation are found to effectively disrupt peptide aggregation, and they can be carried for sequential ligations toward protein synthesis. The effectiveness and generality of this strategy have been demonstrated with total syntheses of programmed cell death protein 1 immunoglobulin like V-type domain and extracellular domain.

Abstract
Interferon-γ (IFN-γ) is a glycoprotein that is responsible for orchestrating numerous critical immune induction and modulation processes and is used clinically for the treatment of a number of diseases. Herein, we describe the total chemical synthesis of homogeneously glycosylated variants of human IFN-γ using a tandem diselenide-selenoester ligation-deselenization strategy in the C- to N-terminal direction. The synthetic glycoproteins were successfully folded, and the structures and antiviral functions were assessed.

Abstract
Here, we describe an Se-auxiliary mediated ligation protocol capable of rapid native chemical ligations at sterically hindered junctions, followed by in situ auxiliary cleavage under neutral conditions without affecting unprotected Cys residues. This auxiliary, which is prepared from phenyl acetaldehyde in one step, can be conveniently attached to the N-terminal region of a peptide via a reductive amination or coupling reaction. We demonstrated this methodology by synthesizing two protein samples.
