  • HY-122575
    Aurintricarboxylic acid
    		Antagonist
    Aurintricarboxylic acid is a nanomolar-potency, allosteric antagonist with selectivity towards αβ-methylene-ATP-sensitive P2X1Rs and P2X3Rs, with IC50s of 8.6 nM and 72.9 nM for rP2X1R and rP2X3R, respectively. Aurintricarboxylic acid is a potent anti-influenza agent by directly inhibiting the neuraminidase. Aurintricarboxylic acid is an inhibitor of topoisomerase II and apoptosis. Aurintricarboxylic acid is a selective inhibitor of the TWEAK-Fn14 signaling pathway. Aurintricarboxylic acid also acts as a cystathionine-lyase (CSE) inhibitor with an IC50 of 0.6 μM. Aurintricarboxylic acid is a modifier of miRNAs that regulate miRNA function, with an IC50 of 0.47 µM.
  • HY-101588
    Gefapixant
    		Antagonist 99.33%
    Gefapixant is an orally active and potent purinergic P2X3 receptor (P2X3R) antagonist, with IC50 values of ~30 nM versus recombinant hP2X3 homotrimers and 100-250 nM at hP2X2/3 heterotrimeric receptors. Gefapixant can be used for the research of chronic cough and knee osteoarthritis.
  • HY-15568
    A-317491
    		Antagonist 98.77%
    A-317491 is a potent, selective and non-nucleotide antagonist of P2X3 and P2X2/3 receptors, with Kis of 22, 22, 9, and 92 nM for hP2X3, rP2X3, hP2X2/3, and rP2X2/3, respectively. A-317491 is highly selective (IC50>10 μM) over other P2 receptors and other neurotransmitter receptors, ion channels, and enzymes. A-317491 reduces inflammatory and neuropathic pain by blocking P2X3 and P2X2/3 receptor-mediated calcium flux.
  • HY-135976
    P2X3 antagonist 34
    		Antagonist 99.71%
    P2X3 antagonist 34 is a potent, selective and orally active P2X3 homotrimeric receptor antagonist with IC50s of 25 nM, 92 nM and 126 nM for human P2X3, rat P2X3 and guinea pig P2X3 receptors, respectively. P2X3 antagonist 34 is less active against human, rat and guinea pig P2X2/3 heterotrimeric receptors. P2X3 antagonist 34 has strong anti-tussive effect.
  • HY-16322
    Minodronic acid
    		Antagonist ≥98.0%
    Minodronic acid (YM-529) is a third-generation bisphosphonate that directly and indirectly prevents proliferation, induces apoptosis, and inhibits metastasis of various types of cancer cells. Minodronic acid (YM-529) is an antagonist of purinergic P2X2/3 receptors involved in pain.
  • HY-109067A
    Opiranserin hydrochloride
    		Antagonist 99.44%
    Opiranserin (VVZ-149) hydrochloride, a non-opioid and non-NSAID analgesic candidate, is a dual antagonist of glycine transporter type 2 (GlyT2) and serotonin receptor 2A (5HT2A), with IC50s of 0.86 and 1.3 μM, respectively. Opiranserin hydrochloride shows antagonistic activity on rP2X3 (IC50=0.87 μM). Opiranserin hydrochloride is development as an injectable agent for the treatment of postoperative pain.
  • HY-15568A
    A-317491 sodium salt hydrate
    		Antagonist 99.88%
    A-317491 sodium salt hydrate is a potent, selective and non-nucleotide antagonist of P2X3 and P2X2/3 receptors, with Kis of 22, 22, 9, and 92 nM for hP2X3, rP2X3, hP2X2/3, and rP2X2/3, respectively. A-317491 sodium salt hydrate is highly selective (IC50>10 μM) over other P2 receptors and other neurotransmitter receptors, ion channels, and enzymes. A-317491 sodium salt hydrate reduces inflammatory and neuropathic pain by blocking P2X3 and P2X2/3 receptor-mediated calcium flux.
  • HY-19978
