GS143 is a selective IκBα ubiquitination inhibitor with an IC50 of 5.2 μM for SCFβTrCP1-mediated IκBα ubiquitylation. It suppresses NF-κB activation and transcription of target genes without inhibiting proteasome activity. GS143 has anti-asthm[atic] properties.

AS1810722, a fused bicyclic pyrimidine derivative, is an orally active and potent inhibitor of STAT6, demonstrating an IC50 of 1.9 nM. It exhibits effective inhibition of CYP3A4, positioning it as a promising candidate for research into allergic diseases, including asthma and atopic conditions.

Eosinophil Peroxidase, Human (EC 1.11.1.7), is an enzyme found in eosinophils, which are innate immune cells of humans and mammals. This heme peroxidase enzyme functions by oxidizing halide ions into reactive oxygen species with bactericidal properties, damaging bacterial cell walls with cations, and modifying amino acid residues in proteins post-translationally.

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.

Flunisolide (Rhinalar) is a synthetic corticosteroid with anti-inflammatory and antiallergic properties.

WHI-P97 is a rationally designed potent inhibitor of JAK-3. IC50 value: Target: JAK3 Treatment of mast cells with WHI-P97 inhibited the translocation of 5-lipoxygenase (5-LO) from the nucleoplasm to the nuclear membrane and consequently 5-LO-dependent leukotriene (LT) synthesis after IgE receptor/FcepsilonRI crosslinking by >90% at low micromolar concentrations. WHI-P97 did not directly inhibit the enzymatic activity of 5-LO, but prevented its translocation to the nuclear membrane without affecting the requisite calcium signal.

Mepolizumab (SB 240563) is a humanized monoclonal antibody that neutralizes IL-5, and can be utilized in research on severe eosinophilic asthma and eosinophilic granulomatosis with polyangiitis.

Theophylline (1,3-Dimethylxanthine) is a methyl xanthine derivative from tea with diuretic, smooth muscle relaxant, bronchial dilation, cardiac, and central nervous system stimulant activities. It inhibits the 3', 5'-cyclic nucleotide phosphodiesterase that degrades cyclic AMP, thus potentiating the actions of agents that act through adenylyl cyclases and cyclic AMP.

Theophylline monohydrate (Quibron) appears to inhibit phosphodiesterase and prostaglandin production, regulate calcium flux and intracellular calcium distribution, and antagonize adenosine. Theophylline monohydrate is a natural alkaloid derivative of xanthine isolated from the plants Camellia sinensis and Coffea arabica. Physiologically, this agent relaxes the bronchial smooth muscle, produces vasodilation (except in cerebral vessels), stimulates the CNS, stimulates the cardiac muscle, induces diuresis, and increases gastric acid secretion; it may also suppress inflammation and improve contractility of the diaphragm.

Piclamilast (RP 73401) is a PDE4 inhibitor.

Adriforant (PF-3893787,ZPL-3893797) is a competitive H4 (histamine receptor 4) antagonist that antagonizes histamine-induced phosphorylation of ERK, normalizes histamine-induced transcriptional changes in mast cells and reduces histamine-dependent Ca2+ fluxes in neurons, which alleviates itching and skin inflammation in mice

Benralizumab (MEDI-563) is a monoclonal antibody targeting the interleukin-5 receptor alpha (IL-5Rα). It enhances antibody-dependent cell-mediated cytotoxicity, leading to a rapid depletion of eosinophils. Benralizumab is used for severe eosinophilic asthma and can be employed to prevent exacerbations of chronic obstructive pulmonary disease.

YM-90709 is a new-type antagonist inhibiting the binding of interleukin-5 to the interleukin-5 receptor.

Enoximone is a selective inhibitor of phosphodiesterase III (PDE3), with treatment of congestive heart failure.

Uvaol is present in olives and virgin olive oil with anti-inflammatory, anti-proliferative, and vasorelaxant activities.

S-Y048 is an Oxoeicosanoid (OXE) receptor antagonist that inhibits allergen-induced eosinophil infiltration into the skin of experimentally sensitized rhesus monkeys to house dust mites and inhibits lung inflammation caused by aerosolized allergen challenge. S-Y048 can be used to study asthma and other eosinophilic diseases.

Cetirizine is a second-generation selective H1-histamine receptor antagonist with antiallergic effects that inhibits eosinophil chemotaxis during allergic reactions. Cetirizine has minimal central nervous system depressant effects.

Reslizumab (Sch 55700) is a humanized immunoglobulin G (IgG)4 κ monoclonal antibody that binds to human interleukin 5, thereby decreasing eosinophil production and survival.Reslizumab improves lung function, induces a decrease in eosinophil production and maturation, and may be used in the study of asthma.

Apafant (WEB 2086) is a highly potent platelet activating factor (PAF) antagonist that blocks eosinophil activation and can be used to study experimental allergic conjunctivitis in guinea pigs.

TAK-661 is an inhibitor of eosinophil chemotaxis (eosinophil chemotaxis) that significantly alleviates late-phase bronchoconstriction while inhibiting the proliferation of eosinophils in bronchoalveolar lavage (BAL) and their infiltration into the airway walls.

Anti-inflammatory agent 104 (Compound 26) is an anti-inflammatory compound. It inhibits TNF-α synthesis and release in the U937 human macrophage cell line with an IC50 of 0.024 nM. Additionally, Anti-inflammatory agent 104 reduces eosinophil levels in rat lungs by 63%.

Israpafant is a selective antagonist for the platelet-activating factor receptor ( IC50 = 0.84nM). Israpafant inhibits PAF-induced human platelet aggregation. Israpafant inhibits the activation of eosinophil cells and consequently delays the development o

NVP-QAV-680 is a potent and selective antagonist of CRTh2 receptor. NVP-QAV-680 has nM functional potency for inhibition of CRTh2 driven human eosinophil and Th2 lymphocyte activation in vitro.

PAF C-18:1 is a naturally occurring phospholipid produced by cells upon stimulation and plays a role in the establishment and maintenance of the inflammatory response. It is less potent than PAF C-16 and PAF C-18 in the induction of neutrophil chemotaxis, but is equipotent to PAF C-16 and PAF C-18 in promoting eosinophil migration. PAF C-18:1 activates the PAF receptor and has been used in antibody binding experiments to determine the importance of an acyl linkage at the sn-2 position for recognition at this receptor.
