Product Description & Background

NYAD-1 _HIV-1 Capsid Stapled Peptide

Antiviral Peptides

 

NYAD-1 is a hydrocarbon-stapled α-helical peptide derived from the HIV-1 capsid assembly inhibitor CAI sequence. The peptide is designed to stabilize the native α-helical conformation required for binding to HIV-1 capsid protein interfaces. Hydrocarbon stapling enhances structural rigidity, protease resistance, and cellular uptake compared to the corresponding linear peptide. NYAD-1 is widely used as a research tool to investigate capsid assembly, viral maturation, and protein–protein interactions involved in HIV-1 replication.

Disease Target

Targets HIV-1 infection (AIDS) by disrupting viral capsid assembly. 

Stapling Strategy

NYAD-1 is synthesized by incorporating Fmoc-(S)-2-(4-pentenyl)alanine (Fmoc-(S5)-OH, CAS: 288617-73-2) residues at i, i+4 positions within the CAI-derived sequence during solid-phase peptide synthesis (SPPS). The hydrocarbon staple is generated via ruthenium-catalyzed ring-closing olefin metathesis, forming a covalent constraint that stabilizes the α-helical conformation and enhances structural rigidity.
