Leukotriene C4 (LTC4) is an arachidonate lipid mediator that regulates leukocyte recruitment and function at sites of inflammation.Leukotriene C4 is a mediator of bronchoconstriction, mucus hypersecretion, and eosinophilia, and has a mediating role in urticaria.

CP-96021 hydrochloride is a potent and orally active antagonist of leukotriene D4 (LTD4)/platelet activating factor receptor (Kis: 34 nM and 37 nM).

AS-35 is an orally effective, potent, and selective antagonist of leukotrienes, antagonizing LTC4-, LTD4-, and LTE4-induced ileum contractions with IC50 values of 8 nM, 4 nM, and 3 nM, respectively. It exhibits antiallergic activities.

RG-12525(NID 525) is an orally available, selective and competitive leukotriene D (LTD) antagonist that inhibits LTC4, LTD4 and LTE4-induced contraction of guinea pig thin-walled bands, with IC50 values of 2.6 nM, 2.5 nM, and 7 nM, respectively.RG-12525 inhibits CYP3A4, with a Ki value of 0.5 µM. RG-12525 is a novel and potent PPAR-γ agonist (IC50 value of about 60 nM) with species specificity for the study of asthma.

CI-949 is an allergic mediator release inhibitor that inhibits the release of leukotriene C4/D4 (LTC4/LTD4), histamine, and thromboxane B2 (TXB2) with IC50 values of 0.5 μM, 11.4 μM, and 0.1 μM, respectively.

LM-1484 displays a higher affinity for 3H-LTC4 sites and is an antagonist of CysLT1 receptor.

Quinotolast sodium inhibits histamine, LTC4 and PGD2 release in a concentration-dependent manner in the concentration range of 1-100 μg/mL.

Nedocromil (FPL 59002) inhibits the action or formation of multiple mediators. Which including histamine, leukotriene C4 (LTC4), and prostaglandin D2 (PGD2).

Ablukast (Ro 23-3544) is a leukotriene receptor antagonist that functions as an anti-asthmatic.

R112 is an ATP-competitive inhibitor of Syk kinase. Ki=6 nM,IC50=226 nM.

AZD9898 is an inhibitor of leukotriene-C4 synthetase with an IC50 of 0.28 nM. AZD9898 can be used in studies about asthma. AZD9898 mitigates the GABA binding and hepatic toxicity signal.

Pranlukast (ONO-1078) is a cysteinyl leukotriene receptor-1 antagonist. It antagonizes or reduces bronchospasm caused, principally in asthmatics, by an allergic reaction to accidentally or inadvertently encountered allergens.

Hydrocortisone (Cortisol) is a glucocorticoid hormone secreted by the adrenocortex. Hydrocortisone agonizes the glucocorticoid receptor, which promotes proteolytic metabolism, gluconeogenesis, capillary wall stabilization, and renal calcium excretion, as well as suppressing immune and inflammatory responses.

TK05 is a potent and selective leukotriene C4 synthase (LTC4S) inhibitor with an IC50 of 95 nM.

GJG057 is a highly efficient and selective Leukotriene C4 synthase (LTC4S) inhibitor with an IC50 of 44 nM in human whole blood LTC4 release assays and oral activity. It demonstrates anti-inflammatory efficacy in a mouse asthma exacerbation model and can be used for the treatment of allergic inflammation.

5-O-Demethylnobiletin (5-DEMETHYLNOBILETIN) is a natual product, has anti-inflammatory activity, it may act through a direct inhibition of 5-LOX, without affecting the expression of COX-2.

Pranlukast hemihydrate (ONO-1078 hemihydrate) is a selective and potent leukotriene (LT) antagonist with anti-asthmatic activity that inhibits [3H]LTD4 and [3H]LTE4 binding to lung membranes and antagonizes LTC4-induced constriction of guinea-pig airways.Pranlukast hemihydrate is used in the study of asthma. Pranlukast hemihydrate is used in the study of asthma.

HAMI 3379 (HAMI3379) is a selective cysteinyl leukotriene receptor 2 (CysLT2) antagonist that dose- and time-dependently attenuates brain damage and inhibits microglial cell inflammation following focal cerebral ischemia in rats and attenuates ischemia-like neuronal damage by inhibiting microglial activation.

Gemilukast (ONO-6950) is an orally active and potent dual inhibitor of cysteinyl leukotriene 1 and 2 receptors (CysLT1 and CysLT2), inhibits LTC 4-induced bronchoconstriction, and is inhibitory to human CysLT1 and CysLT2, and may be used in the treatment of asthma.
