P2X1 Receptor Antagonists (9):

Cat. No. Product Name Effect Purity
  • HY-112461A
    NF449 octasodium
    		Antagonist ≥99.0%
    NF449 octasodium is a highly potent P2X1 receptor antagonist, with IC50s of 0.28, 0.69, and 120 nM for rP2X1, rP2X1+5, P2X2+3, respectively. NF449 octasodium is a Gsα-selective G Protein antagonist. NF449 octasodium suppresses the rate of GTP[γS] binding to Gsα-s, inhibits the stimulation of adenylyl cyclase activity, and blocks the coupling of β-adrenergic receptors to Gs.
  • 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-101044
    PPADS tetrasodium
    		Antagonist 99.9%
    PPADS tetrasodiuma is a non-selective P2X receptor antagonist. PPADS tetrasodiuma blocks recombinant P2X1, -2, -3, -5 with IC50s ranging from 1 to 2.6 μM. PPADS tetrasodiuma blocks native P2Y2-like (IC50~0.9 mM) and recombinant P2Y4 (IC50~15 mM) receptors. PPADS tetrasodiuma is an inhibitor of the reverse mode of the Na/Ca2+ exchanger in guinea pig airway smooth muscle.
  • HY-108676
    NF023 hexasodium
    		Antagonist 99.99%
    NF023 hexasodium is a selective and competitive P2X1 receptor antagonist, with IC50 values of 0.21 μM, 28.9 μM, > 50 μM and > 100 μM for human P2X1, P2X3, P2X2, and P2X4-mediated responses respectively.
  • HY-D0976
    NF279
    		Antagonist 98.5%
    NF279 is a selective P2X1 receptor antagonist and NTPDase inhibitor, with a P2X1 IC50 value of 19 nM. NF279 suppresses GABA-evoked currents, reduces ATP-excited respiratory activity, alters hypoglossal nerve burst parameters, and blocks CXCR4, CCR5, CXCR3, and CXCR7-mediated calcium responses. NF279 arrests HIV-1 fusion downstream of CD4 binding, inhibits R5- and X4-tropic HIV-1 strains. NF279 can be used for the research of HIV-1 infection.
  • HY-108675
    PPNDS tetrasodium
    		Antagonist
    PPNDS tetrasodium is a selective and competitive meprin β inhibitor (IC50: 80 nM, Ki: 8 nM), and also inhibits ADAM10 (IC50: 1.2 μM). PPNDS tetrasodium is also a P2X1 receptor antagonist. PPNDS is an agonist for the ATP receptor of Paramecium. PPNDS tetrasodium potently inhibits polymerases from viruses. PPNDS tetrasodium can be used in the research of infection and cancers.
  • HY-D1199
    Blue FPG-A trisodium
    		Antagonist
    Blue FPG-A trisodium is a selective antagonist of P2X1 receptor and P2Y1 receptor with IC50 values of 35.5 μM and 2.6 μM, respectively. Blue FPG-A trisodium is a structural isomer of the components of Reactive Blue 2 (RB2).
  • HY-108960
    PPADS
    		Antagonist
    PPADS is a P2X receptor (P2X Receptor) antagonist and a reversible competitive antagonist of NAADP receptors, with IC50 values of 68 nM (P2X1) and 214 nM (P2X3), respectively. PPADS alleviates pain-related behaviors in the central and peripheral nervous systems of mice after peripheral neuropathy, inhibits the overproduction of IL-1β, IL-6, iNOS and nNOS, and suppresses the hydrolytic activity of extracellular ATPase. PPADS blocks ATP-mediated inward currents on recombinant rat P2X1 and P2X3 receptors, and inhibits purinergic nerve stimulation-induced contraction of rabbit bladder detrusor muscle. PPADS is applicable to research related to neuropathic pain.
