Description

(Boc-Lys9)-Neurotensin (9-13)-Methyl Ester CAS NO 89545-20-0 is a protected peptide fragment derived from the neurotensin sequence, specifically the C-terminal pentapeptide region. This compound is a critical synthetic intermediate and research tool for studying neurotensin receptor interactions and signaling pathways. It is primarily utilized by pharmaceutical researchers, peptide chemists, and academic laboratories engaged in neuroscience, endocrinology, and drug discovery programs.

Application

• Peptide Synthesis Intermediate: A key building block for the solid-phase or solution-phase synthesis of full-length neurotensin analogs and related peptide conjugates.
• Neuroscience Research: Used in structure-activity relationship (SAR) studies to elucidate the bioactive core of neurotensin and its interaction with NTS1 and NTS2 receptors.
• Biochemical Probe Development: Serves as a precursor for creating labeled (e.g., fluorescent, radioactive) probes for receptor binding assays and imaging studies.
• Medicinal Chemistry: Employed in the design and development of novel neurotensin-based therapeutics for neurological disorders and cancers.
• Reference Standard: Used as a chromatographic or spectroscopic reference standard in analytical method development and quality control for peptide APIs.
