Usage

General Description

AC-GLY-LEU-OH is a chemical compound composed of three amino acids: acetyl (AC), glycine (GLY), leucine (LEU), and a carboxy terminal group (OH). AC-GLY-LEU-OH is commonly used in peptide synthesis and is a part of the peptide chain. The acetyl group at the N-terminus helps to protect the amino group during the synthesis process, while the carboxy terminal group provides a free carboxylic acid for further chemical modifications. Glycine and leucine are both essential amino acids that play important roles in protein synthesis and various metabolic processes within the body. AC-GLY-LEU-OH may be used in a variety of research and industrial applications, including drug development, biochemical research, and as a building block for more complex peptide structures. Overall, this compound is valuable for its role in peptide synthesis and its potential to be manipulated for different chemical purposes.

Postsynthetic Modification of Phenylalanine Containing Peptides by C-H Functionalization

New methods for peptide modification are in high demand in drug discovery, chemical biology, and materials chemistry; methods that modify natural peptides are particularly attractive. A Pd-catalyzed, C-H functionalization protocol for the olefination of phenylalanine residues in peptides is reported, which is compatible with common amino acid protecting groups, and the scope of the styrene reaction partner is broad. Bidentate coordination of the peptide to the catalyst appears crucial for the success of the reaction.

Peptide ligation by chemoselective aminonitrile coupling in water

Amide bond formation is one of the most important reactions in both chemistry and biology1–4, but there is currently no chemical method of achieving α-peptide ligation in water that tolerates all of the 20 proteinogenic amino acids at the peptide ligation site. The universal genetic code establishes that the biological role of peptides predates life’s last universal common ancestor and that peptides played an essential part in the origins of life5–9. The essential role of sulfur in the citric acid cycle, non-ribosomal peptide synthesis and polyketide biosynthesis point towards thioester-dependent peptide ligations preceding RNA-dependent protein synthesis during the evolution of life5,9–13. However, a robust mechanism for aminoacyl thioester formation has not been demonstrated13. Here we report a chemoselective, high-yielding α-aminonitrile ligation that exploits only prebiotically plausible molecules—hydrogen sulfide, thioacetate12,14 and ferricyanide12,14–17 or cyanoacetylene8,14—to yield α-peptides in water. The ligation is extremely selective for α-aminonitrile coupling and tolerates all of the 20 proteinogenic amino acid residues. Two essential features enable peptide ligation in water: the reactivity and pKaH of α-aminonitriles makes them compatible with ligation at neutral pH and N-acylation stabilizes the peptide product and activates the peptide precursor to (biomimetic) N-to-C peptide ligation. Our model unites prebiotic aminonitrile synthesis and biological α-peptides, suggesting that short N-acyl peptide nitriles were plausible substrates during early evolution.
