Cat. No. Product Name Effect Purity
  • HY-N0164
    Matrine
    		Agonist ≥98.0%
    Matrine (Matridin-15-one) is an alkaloid found in plants from the Sophora genus that can act as a kappa opioid receptor and u-receptor agonist. Matrine has a variety of pharmacological effects, including anti-cancer, anti-oxidative stress, anti-inflammation and anti-apoptosis effects. Matrine is potential in the research of disease like human non-small cell lung cancer, hepatoma, papillary thyroid cancer and acute kidney injury (AKI).
  • HY-P1333
    Dynorphin A
    		Agonist 98.59%
    Dynorphin A is an endogenous opioid peptide involved in inhibitory neurotransmission in the central nervous system (CNS). Dynorphin A is a highy potent kappa opioid receptor (KOR) agonist, and is also an agonist for other opioid receptors, such as mu (MOR) and delta (DOR). Dynorphin A can induce neuronal death, and can be used in the research of neurological disease.
  • HY-P0088
    Porcine dynorphin A(1-13)
    		Agonist 98.83%
    Porcine dynorphin A (1-13) is a potent, endogenous κ opioid receptor agonist and is antinociceptive at physiological concentrations.
  • HY-163277
    PIPE-3297
    		Agonist
    PIPE-3297 (compound 25) is a selective kappa opioid receptor (KOR) agonist, which activates the G-protein signaling with EC50 of 1.1 nM and exhibits lowβ-arrestin-2 recruitment activity (10%). PIPE-3297 induces myelination and reveals an anti-inflammatory activity.
  • HY-P1594A
    Dynorphin A (1-10) (TFA)
    		Agonist 98.19%
    Dynorphin A (1-10) (TFA), an endogenous opioid neuropeptide, binds to extracellular loop 2 of the κ-opioid receptor. Dynorphin A (1-10) (TFA) also blocks NMDA-activated current with an IC50 of 42.0 μM.
  • HY-12363
    U-69593
    		Agonist ≥99.0%
    U-69593 is a potent and selective κ1-opioid receptor agonist. U-69593 attenuates addictive agent-induced behavioral sensitization in the rat. U-69593 reduces anxiety and enhances spontaneous alternation memory in mice. U-69593 reduces calcium-dependent dialysate levels of dopamine and glutamate in the ventral striatum.
  • HY-151811
    NAQ
    		Agonist
    NAQ is a potent and selective μ opioid receptor partial agonist, with a Ki of 0.55 nM. NAQ shows selectivity for Mu opioid receptor over the δ receptor (Ki=132.50 nM) and the κ receptor (Ki=26.45 nM). NAQ can be used for the research of opioid withdrawal or dependence.
  • HY-P3870
    DALDA
    		Agonist
    DALDA is a potent and highly selective μ-opioid receptor agonist with a Ki of 1.69 nM. DALDA shows antinociceptive and respiratory effects.
  • HY-P4679
    (N-Me-Tyr1,N-Me-Arg7,D-Leu-NHEt8)-Dynorphin A (1-8)
    		Agonist

  • HY-P1333A
    Dynorphin A TFA
    		Agonist
    Dynorphin A TFA is an endogenous opioid peptide involved in inhibitory neurotransmission in the central nervous system (CNS). Dynorphin A TFA is a highy potent kappa opioid receptor (KOR) agonist, and is also an agonist for other opioid receptors, such as mu (MOR) and delta (DOR). Dynorphin A TFA can induce neuronal death, and can be used in the research of neurological disease.
  • HY-P3445
