Fmoc-(R)-2-(7-octenyl) Ala-OH is an unnatural Fmoc-protected amino acid and modification module. Fmoc-(R)-2-(7-octenyl) Ala-OH serves as a key building block for all-hydrocarbon cross-linking modification of antimicrobial peptides, and facilitates the generation of stapled peptide derivatives. When introduced into specific sites of the parent peptide, Fmoc-(R)-2-(7-octenyl) Ala-OH effectively increases the α-helix content of the peptide chain, thereby significantly enhancing its antimicrobial activity and proteolytic stability. Fmoc-(R)-2-(7-octenyl) Ala-OH is widely used in research on bacterial infections and the development of related antimicrobial agents . Stapled peptide is a specially chemically modified polypeptide. It locks the peptide chain into a stable α-helical structure by introducing a "staple"-like chemical bridge (usually an all-carbon backbone) at specific positions of the peptide chain.

Research Areas:  

Infection

BOC-(1R,3S)-3-aminocyclopentane carboxylic acid ((1S,3S)-3-[(tert-Butoxycarbonyl)amino]cyclopentanecarboxylic acid) is a conformationally constrained peptide building block and a key component of SARS-CoV-2 main protease (Mpro) inhibitors. When incorporated into macrocyclic peptides, BOC-(1R,3S)-3-aminocyclopentane carboxylic acid not only helps generate high-affinity Mpro inhibitors by preorganizing the secondary structure of peptides, but also exerts sequence-dependent functional inhibition on the hydrolytic activity of Mpro. BOC-(1R,3S)-3-aminocyclopentane carboxylic is widely used in COVID-19-related research .
