Description

Alanylalanyl-S-(4-(n-(2-Thioethyl))Aminopyridine-2,6-Dicarboxylic Acid)Cysteine is a specialized synthetic peptide derivative designed for advanced biochemical and pharmaceutical research. This compound is valued for its unique structure, which incorporates a modified cysteine residue linked to a dipeptide backbone and a functionalized pyridine moiety, making it a critical intermediate in the development of novel enzyme inhibitors and targeted drug conjugates. It is primarily sought by research institutions and pharmaceutical companies engaged in protease inhibition studies, bioconjugation chemistry, and the synthesis of next-generation therapeutic agents.

Application

• Pharmaceutical Intermediate: Key building block for synthesizing novel protease inhibitors and targeted drug candidates.
• Biochemical Research: Used as a substrate or inhibitor in enzymatic assays to study protease activity and mechanism.
• Bioconjugation: The reactive thioethyl-aminopyridine group enables site-specific labeling and cross-linking of proteins and peptides.
• Chemical Biology Probes: Development of activity-based probes (ABPs) for profiling enzyme families in complex biological systems.
• Material Science: Potential precursor for functionalized surfaces or polymers in biosensor development.
