endomorphin 1

Endomorphin 1 is a high affinity and selective agonist of the μ-opioid receptor and displays reasonable affinities for kappa3 binding sites (Ki: 20~30 nM).

N-terminally acetylated Endomorphin-1 acetate (Ac-L-Tyr-L-Pro-L-Trp-L-Phe-CONH2) is a modified Endomorphin-1.

N-terminally acetylated Endomorphin-1 is a modified Endomorphin-1.

Endomorphin 1 acetate is a selective and highly effective μ-opioid receptor agonist with anti-nociceptive and analgesic effects. Endomorphin 1 acetate shows high affinity for kappa3 and can be used to study neurological diseases.

BMS986187 is a novel Potent and Selective Positive Allosteric Modulators of the delta-Opioid Receptor.

BMS-986122 (BMS 986122) is a positive allosteric modulator of μ-opioid receptors that increases β-arrestin recruitment stimulated by endomorphin 1 in U2OS-OPRM1 human osteosarcoma cells expressing μ-opioid receptors (EC50 = 3 μM).

ADL 08-0011 is an active metabolite of the μ-opioid receptor antagonist alvimopan. It is produced from alvimopan via amide hydrolysis by gut microbiota. ADL 08-0011 is a μ-opioid receptor antagonist (Ki = 0.25 nM). It is selective for μ-opioid receptors over κ- and δ-opioid receptors (Kis = 15.8 and 31.6 nM, respectively). ADL 08-0011 inhibits endomorphin 1-induced inhibition of electrically induced contraction of isolated guinea pig ileum (pA2 = 9.4). In vivo, ADL 08-0011 (0.03-1 mg/kg) reverses loperamide-induced delayed gastric emptying in a rat model of castor oil-induced diarrhea.
