Description

L-Argininamide, N2-(1-Oxooctadecyl)-L-Arginyl-L-Arginyl-L-Arginyl-L-Arginyl-L-Arginyl-L-Arginyl-L-Arginyl- is a high-purity, synthetic peptide derivative featuring a unique octadecanoyl (C18) fatty acid chain conjugated to a hepta-arginine sequence. This molecular architecture is engineered to enhance cellular penetration and bioavailability, making it a critical intermediate for advanced research and therapeutic development. It is primarily utilized by pharmaceutical R&D teams, biotechnology companies, and academic institutions focused on peptide-based drug discovery, cell-penetrating peptide (CPP) studies, and novel delivery system formulation.

Application

• Pharmaceutical Research & Development: As a key intermediate in the synthesis of novel peptide therapeutics and prodrugs.
• Cell-Penetrating Peptide (CPP) Studies: Utilized as a model compound to investigate mechanisms of cellular uptake and intracellular delivery of bioactive cargo.
• Drug Delivery System Development: Serves as a functional component for creating lipopeptide-based delivery platforms to improve the solubility and targeting of hydrophobic drugs.
• Bioconjugation & Protein Labeling: The reactive groups and polycationic nature facilitate conjugation with various molecules for diagnostic or therapeutic purposes.
• Cosmeceutical Actives: Potential use in high-end skincare formulations for its peptide signaling and potential skin barrier interaction properties.
• Biochemical Research: Used as a substrate or inhibitor in enzymatic studies related to arginine metabolism and protein-protein interactions.
