LTE4 Antagonists (6):

Cat. No. Product Name Effect Purity
  • HY-19989A
    MK-571 sodium
    		Antagonist 99.24%
    MK-571 (L-660711) sodium is an orally active, potent and selective competitive leukotriene D4 (LTD4) receptor antagonist, with Ki values of 0.22 and 2.1 nM in guinea pig and human lung membranes, respectively. MK-571 sodium is also a inhibitor of multidrug resistance-associated protein MRP4 (ABCC4) and ABCC1 (MRP1). MK-571 sodium inhibits constitutive and antigen-stimulated S1P (sphingosine-1-phosphate) release.
  • HY-B0290
    Pranlukast
    		Antagonist 98.18%
    Pranlukast is a highly potent, selective and competitive antagonist of peptide leukotrienes. Pranlukast inhibits [3H]LTE4, [3H]LTD4, and [3H]LTC4 bindings to lung membranes with Kis of 0.63±0.11, 0.99±0.19, and 5640±680 nM, respectively.
  • HY-19989
    MK-571
    		Antagonist 98.56%
    MK-571 (L-660711) is an orally active, potent and selective competitive leukotriene D4 (LTD4) receptor antagonist, with Ki values of 0.22 and 2.1 nM in guinea pig and human lung membranes, respectively. MK-571 is also a MRP4 and ABCC1 (MRP1) inhibitor. MK-571 inhibits constitutive and antigen-stimulated S1P (sphingosine-1-phosphate) release.
  • HY-B0290A
    Pranlukast hemihydrate
    		Antagonist 99.28%
    Pranlukast hemihydrate is a highly potent, selective and competitive antagonist of peptide leukotrienes. Pranlukast inhibits [3H]LTE4, [3H]LTD4, and [3H]LTC4 bindings to lung membranes with Kis of 0.63±0.11, 0.99±0.19, and 5640±680 nM, respectively.
  • HY-14938
    Tipelukast
    		Antagonist 99.40%
    Tipelukast (KCA 757) is a sulfidopeptide leukotriene receptor antagonist, an orally bioavailable anti-inflammatory agent and used for the treatment of asthma.
  • HY-101946
    AS-35
    		Antagonist
    AS-35 is an orally effective, potent and selective antagonist of leukotrienes, antagonizes LTC4-, LTD4 and LTE4-induced contractions of the ileum with IC50 values of 8 nM, 4 nM and 3 nM, respectively, and has antiallergic activities.
