Opioid Receptor Isoform Comparison

Opioid Receptor Antagonists (112):

Cat. No. Product Name Effect Purity
  • HY-A0118S1
    Naloxegol-13C,d2
    		Antagonist
    Naloxegol-13C,d2 (NKTR-118-13C,d2) is 13C labeled Naloxegol. Naloxegol (NKTR-118; AZ-13337019) is a μ-opioid-receptor antagonist. Naloxegol inhibits opioid binding in μ-opioid receptors in the gastrointestinal tract and effective for alleviating opioid-induced constipation.
  • HY-13243S1
    Alvimopan-d7
    		Antagonist
    Alvimopan-d7 (ADL 8-2698-d7) is deuterium labeled Alvimopan. Alvimopan (ADL 8-2698) is a potent, selective, orally active and reversible μ-opioid receptor antagonist, with an IC50 of 1.7 nM. Alvimopan has selectivity for μ-opioid receptor (Ki=0.47 nM) over κ- and δ-opioid receptors (Kis=100, 12 nM, respectively). Alvimopan can be used for the research of postoperative ileus.
  • HY-101307
    BNTX maleate
    		Antagonist
    BNTX (7-Benzylidenenaltrexone) maleate is a δ1-opioid receptor antagonist with the Kis of 0.1, 10.8, 13.3, and 58.6 nM for δ1, δ2-, μ-, and κ-opioid receptor, respectively. BNTX maleate shows antinociceptive activity.
  • HY-120927A
    Alvimopan metabolite hydrochloride
    		Antagonist
    Alvimopan metabolite hydrochloride is a peripherally restricted Opioid Receptor antagonist that inhibits the amplitude of electrically evoked contractions and spontaneous mechanical activity in guinea pig ileum.
  • HY-13274A
    JTC-801 free base
    		Antagonist
    JTC-801 free base is a selective opioid receptor-like1 (ORL1) receptor antagonist, binding to ORL1 receptor with a Ki value of 8.2?nM.
  • HY-B1485
    Nalmefene hydrochloride
    		Antagonist
    Nalmefene hydrochloride is a long acting opioid (MOR and DOR antagonist), and a partial KOR agonist. Nalmefene hydrochloride is used for opioid overdose and alcohol dependence.
  • HY-169822
    5′-Guanidinonaltrindole
    		Antagonist
    5′-Guanidinonaltrindole (GNTI) is a selective kappa opioid receptor antagonist.
  • HY-W778148
    O,O-Diethyl dithiophosphate-13C4 ammonium
    		Antagonist
    O,O-Diethyl dithiophosphate-13C4 (ammonium) is the 13C labeled isotope of O,O-Diethyl dithiophosphate-13C4 (ammonium).
  • HY-169867
    BNTX
    		Antagonist
    BNTX (7-Benzylidenenaltrexone) is a selective δ1-opioid receptor antagonist. BNTX antagonizes the antisecretory actions of DPDPE (HY-P1334), Deltorphin 2 (HY-P1013), and DAMGO (HY-P0210) competitively. BNTX can be used for research of antinociception.
  • HY-123689A
    Samidorphan hydrochloride
    		Antagonist
    Samidorphan hydrochloride is an orally active opioid system modulator that has a high affinity for binding with μ‐opioid, κ‐opioid, and δ‐opioid receptors. Samidorphan hydrochloride acts as an antagonist at μ‐opioid receptors and acts as a partial agonist at k-opioid and δ‐opioid receptors. Samidorphan hydrochloride primarily acts as an opioid receptor antagonist in vivo.
  • HY-76711S
    Naltrexone-d4
    		Antagonist
    Naltrexone-d4 is deuterium labeled Naltrexone.
  • HY-119733
    BU09059
    		Antagonist
    BU09059 is a potent and selective Kappa-opioid receptor antagonist with a pA2 of 8.62. BU09059 has nanomolar affinity for the κ-receptor, with 15-fold and 616-fold selectivity over μ- and δ-receptors, respectively. BU09059 significantly blocks U50488 (HY-15997B)-induced antinociception.
