US 2018/0274003 A1: Butelase-Mediated Peptide Ligation (2021)
Abstract: The present invention relates to a method of forming a peptide of Formula (I) (P1-Xaa1-Xaa2-P2) by ligating a first peptide of Formula (II) (P1-Xaa1-X—R, wherein X is O or S) to a second peptide of Formula (II I) (Xaa1-Xaa2-P2) by enzymatically cleaving the bond between “Asx” and “X” in the first peptide of Formula (II) and ligating the fragment P1-Asx of the first peptide to the second peptide of Formula (III), wherein the enzymatic cleavage and ligation reaction is catalyzed by butelase 1 (SEQ ID NO: 1) and the peptide of Formula (I) is a depsipeptide, preferably a thiodepsipeptide. Further encompassed are peptides and dendrimeric peptide assemblies prepared using the presently disclosed method, as well as use of the dendrimeric peptide assemblies as a vaccine, medicament, or diagnostic agent, particularly as an antimicrobial agent.

US 2015/0344519 A1: Method Of Synthesizing Peptides, Proteins And Bioconjugates (2016)
Abstract: The invention relates to the synthesis of peptides, proteins and related bioconjugates, and in particular, to such synthesis using a peptide ligation method whereby a C-terminal salicylaldehyde ester peptide is reacted with an aminoacyl-N-hydroxl peptide. The invention also relates to the synthesis of cyclic peptides, including serinyl- or threonyl-containing cyclic peptides. The invention further relates to a solid phase synthesis of C-terminal salicylaldehyde ester peptides.

US 2014/0316105 A1: Method For Modification Of Organic Molecules (2016)
Abstract: The present invention is directed to a method of alkylating a thiol group (R—S—H) or seleno group (R—Se—H) in a target molecule wherein the method comprises: reacting a target molecule comprising at least one thiol group with a compound of formula (I) or (II): wherein R is an acetyl group or any other acyl group or is a group comprising any one of: or wherein R in formula (II) can also be an alkyl group; and wherein R′ is selected from a group consisting of a hydrogen, a methyl group and an ethyl group.

US 2011/0245458 A1: Peptide Nucleic Acid Monomers and Oligomers (2014)
Abstract: Disclosed is a peptide nucleic acid monomer as well as a corresponding peptide nucleic acid molecule. The monomer comprises a terminal amino group and a terminal group A. The terminal amino group and the terminal group A are connected by an aliphatic moiety. The main chain of this aliphatic moiety is free of groups that are charged under physiological conditions.
