Description

L-Tyrosine, N-acetyl-L-cysteinyl-L-cysteinyl-L-α-glutamyl-L-tyrosyl-L-cysteinyl-L-cysteinyl-L-asparaginyl-L-prolyl-L-alanyl-L-cysteinyl-L-threonylglycyl-L-cysteinyl-, cyclic (1→6),(2→10),(5→13)-tris(disulfide) is a complex, high-purity cyclic peptide featuring a unique tris(disulfide) bridge structure, which confers significant stability and specific biological activity. This compound is of critical importance for advanced research and development in the life sciences, particularly in the study of protein folding, enzyme inhibition, and receptor-ligand interactions. It is primarily sought by pharmaceutical R&D teams, biotechnology firms, and academic research institutions focused on peptide-based therapeutics, diagnostic tools, and biochemical probes.

Application

• Pharmaceutical Research & Development: As a key intermediate or reference standard in the discovery and development of novel peptide-based drugs targeting specific biological pathways.
• Biochemical Research: For studying disulfide bond formation, protein folding mechanisms, and structural biology due to its defined cyclic and cross-linked architecture.
• Enzyme Inhibition Studies: Utilized as a potential inhibitor or modulator in enzymatic assays to investigate catalytic mechanisms and identify new therapeutic targets.
• Diagnostic Development: May serve as a component in the development of sensitive immunoassays or biosensors that require specific peptide sequences for target binding.
• Cell Signaling & Proteomics: Used in research exploring intracellular signaling cascades and protein-protein interactions where specific peptide motifs are critical.
• Academic & Contract Research: Supplied to universities and CROs (Contract Research Organizations) for fundamental and applied research projects in chemistry and biology.
