β-Endorphin (1-27), human CAS NO.76622-84-9

β-Endorphin (1-27), human is a naturally occurring N-terminal fragment of the full-length β-endorphin peptide, functioning as a potent endogenous opioid receptor antagonist. Unlike many analgesic peptides, it competitively binds to μ-, δ-, and κ-opioid receptors to block signaling, making it a critical research tool for studying pain modulation, receptor dynamics, and the endogenous opioid system in neuroscience and pharmacology laboratories.

1.MECHANISM OF ACTION

Endomorphin-2 exerts its effects by selectively binding to μ-opioid receptors with high affinity, thereby activating G-protein coupled signaling pathways that inhibit adenylate cyclase and reduce cAMP production. This action leads to the hyperpolarization of neurons and inhibition of neurotransmitter release, effectively blocking pain signal transmission in both the central and peripheral nervous systems. Its mechanism is distinct in its ability to induce the release of other endogenous opioids like dynorphin A, contributing to its complex analgesic profile in preclinical models.

2.PRODUCT INDICATIONS

This product is strictly indicated for research use in biochemical and pharmacological studies, including receptor binding assays, signal transduction research, and in vitro functional characterization of μ-opioid receptor activity. It is particularly valuable for scientists investigating spinal cord-mediated analgesia, neuropathic pain mechanisms, and opioid receptor pharmacology. The peptide is also employed in the screening and development of new analgesic drugs and in studies exploring the physiological roles of endogenous opioid systems.

3.CLINICAL EFFICACY OF PRODUCT

As a research biochemical, β-Endorphin (1-27) is not intended for human therapeutic use. Its efficacy is demonstrated in preclinical research settings, where it has been shown to effectively reverse or prevent analgesia induced by full-length β-endorphin and other opioid agonists in animal models, providing robust data on the modulation of nociceptive thresholds and the physiological role of endogenous opioid fragments.
