内吗啡肽 1

Endomorphin 1，一种高度选择性的，高亲和力的μ-opioid受体激动剂 (K_i: 1.11 nM)，对 kappa₃结合位点具有高亲和力，K_i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(K_i: 1.11 nM), displays reasonable affinities for kappa₃binding sites, withK_ivalue between 20 and 30 nM. Endomorphin 1 has antinociceptive properties^[1]^[2]^[4].

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.
