β-Endorphin, human 是存在于垂体和下丘脑中的重要的内源性肽，为阿片样 (opioid) 受体激动剂，尤其对 μ-opioid 受体和 δ-opioid 受体的亲和性更高；β-Endorphin, human 具有缓解疼痛的功效。

β-Endorphin, human, a prominent endogenous peptide, existing in the hypophysis cerebri and hypothalamus, is an agonist of opioid receptor, with preferred affinity for μ-opioid receptor and δ-opioid receptor; β-Endorphin, human exhibits antinociception activity.

δ Opioid Receptor/DOR

β-Endorphin, human is an agonist of opioid receptor, with preferred affinity for μ-opioid receptor and δ-opioid receptor. β-Endorphin exhibits anti-nociception activity by stimulating ε-opioid receptor, rather than μ-, δ-, and κ-opioid receptor. β-Endorphin has anti-nociception activity. Firstly, β-Endorphin combines together with the opioid receptors in hyperalgesia. Further, β-Endorphin suppresses the release of substance P at the level of spinal cord and blocks the conduction of pain on the primary sensory neurons. Moreover, β-Endorphin activates the endogenous analgesia system located in the CNS. In addition, β-Endorphin inhibits the conduction of pain and agitation of nociceptors to exert an analgesic effect. has not independently confirmed the accuracy of these methods. They are for reference only.
