Description

L-Lysinamide, N-(3-methyl-1-oxobutyl)-L-α-aspartyl-L-threonyl-L-histidyl-L-phenylalanyl-L-prolyl-L-cysteinyl-L-isoleucyl-N6-[N-(1-oxohexadecyl)-L-γ-glutamyl]-L-lysyl-L-phenylalanyl-L-α-glutamyl-L-prolyl-L-arginyl-L-seryl-L-lysylglycyl-L-cysteinyl-, cyclic (6→16)-disulfide is a complex, long-chain peptide derivative featuring a cyclic disulfide bridge and a lipophilic hexadecanoyl (palmitoyl) modification. This sophisticated molecular architecture is critical for its role as a potent and selective bioactive agent, offering high binding affinity and metabolic stability. It is primarily utilized in advanced pharmaceutical research and development, particularly for creating novel therapeutic peptides and targeted drug delivery systems.

Application

• Pharmaceutical R&D: Serves as a key intermediate or active pharmaceutical ingredient (API) in the development of novel peptide-based therapeutics.
• Targeted Drug Delivery: The lipophilic modification enables its use in conjugates designed for enhanced cellular uptake and targeted action.
• Hormone Analog Development: Used in research to create analogs of complex peptide hormones with improved pharmacokinetic profiles.
• Bioconjugation & Probe Synthesis: Acts as a scaffold for attaching labels, dyes, or other functional groups to create research tools and diagnostic probes.
• Receptor Binding Studies: Employed in biochemical assays to study specific receptor-ligand interactions due to its high specificity.
• Cosmeceutical Peptide Synthesis: Potential application in the synthesis of advanced, stabilized anti-aging or bioactive cosmetic peptides.
