Endomorphin 1,一种高度选择性的,高亲和力的μ-opioid受体激动剂 (Ki: 1.11 nM),对 kappa3结合位点具有高亲和力,Ki值为 20 到 30 nM 之间。Endomorphin 1 具有镇痛特性。
生物活性 | Endomorphin 1, a high affinity, highly selective agonist of theμ-opioid receptor(Ki: 1.11 nM), displays reasonable affinities for kappa3binding sites, withKivalue between 20 and 30 nM. Endomorphin 1 has antinociceptive properties[1][2][4]. |
IC50& Target | μ Opioid Receptor/MOR 1.11 nM (Ki) |
|
体外研究 (In Vitro) | Endomorphin 1 inhibitsForskolin(HY-15371) (1 μM) stimulated cyclic AMP formation with a pIC50value of 8.03 in In CHOμ cells[5]. Endomorphin 1 (1-10 μM) increases interleukin-8 secretion in Caco-2 cells[6]. Endomorphin 1 (1 μM) inhibits excitatory transmission in adult rat substantia gelatinosa neurons[7].

体内研究 (In Vivo) | Endomorphin 1 (i.c.v.) shows antinociceptive properties in mice, with an ED50value of 6.16 nM[2]. Endomorphin 1 (50 μg/kg, i.v.) alleviates myocardial ischemia/reperfusion injury (MIRI) by inhibiting the inflammatory response[3].
Animal Model: | ICR mice[2]. | Dosage: | 6.16 nM (ED50) | Administration: | Intracerebroventricularly (i.c.v.) injection | Result: | Inhibited dose-dependently the tail-flick response. |
Animal Model: | Rats[3].
| Dosage: | 50 μg/kg | Administration: | Intravenously following LAD ligation for 25 min, subsequently the LAD was reperfused for 120 min. | Result: | Alleviated MIRI by reducing the production of free radicals. Dncreased LDH and CK-MB activities. Increased SOD activity and decreased MDA content. Decreased IL-6 and TNF-α plasma content. |
