Sodium salicylate (2-Hydroxybenzoic acid sodium salt), a metabolite of acetylsalicylic acid, can inhibit NF-kB and reduce oxidative stress.

1. Prunetin (Prunusetin) significantly reduces serum levels of inflammatory cytokines and mortality in mice challenged with lipopolysaccharide. 2. Prunetin mediates anti-obesity adipogenesis effects by suppressing obesity-related transcription through a feedback mechanism that regulates the expression of adiponectin, adipoR1, adipoR2, and AMPK. 3. Prunetin and biochanin A are potent reducers of NF-κB and ERK activation, zonula occludens 1 tyrosine phosphorylation, and metalloproteinase-mediated shedding activity, which may account for the barrier-improving ability of these isoflavones. 4. Prunetin significantly suppresses ATP-induced mucin secretion from cultured RTSE cells; Prunetin inhibits the production of MUC5AC mucin protein induced by EGF or PMA from NCI-H292 cells; Prunetin also inhibits the expression of MUC5AC mucin gene induced by EGF or PMA from NCI-H292 cells.

Synephrine (Oxedrine) is sympathetic alpha-adrenergic agonist used as a vasoconstrictor in circulatory failure, asthma, nasal congestion, and glaucoma.

9(S),12(S),13(S)-TriHOME is a linoleic acid-derived oxylipin that has diverse biological activities.1,2,3,4It has been found in various plants and is produced in human eosinophils in a 15-lipoxygenase-dependent, soluble epoxide hydrolase-independent manner.1,59(S),12(S)13(S)-TriHOME inhibits antigen-induced β-hexosaminidase release from RBL-2H3 mast cells (IC50= 28.7 μg ml).2It inhibits LPS-induced nitric oxide (NO) production in BV-2 microglia (IC50= 40.95 μM).3In vivo, 9(S),12(S),13(S)-TriHOME (1 g animal) enhances the antiviral IgA and IgG antibody responses induced by a nasal influenza hemagglutinin (HA) vaccine by 5.2- and 2-fold, respectively, in mice.4 1.Hamberg, M., and Hamberg, G.Peroxygenase-catalyzed fatty acid epoxidation in cereal seeds: Sequential oxidation of linoleic acid into 9(S),12(S),13(S)-trihydroxy-10(E)-octadecenoic acidPlant Physiol.110(3)807-815(1996) 2.Hong, S.S., and Oh, J.S.Inhibitors of antigen-induced degranulation of RBL-2H3 cells isolated from wheat branJ.

Lipoxin B4 is a metabolite of arachidonic acid that inhibits leukocyte infiltration and mucus secretion in the nasal mucosa of the upper respiratory tract, exhibiting mucosal protective effects. It is commonly used in studies of allergic inflammation in the upper and lower respiratory tracts.

Epimagnolin A is a lignan obtained from the flower buds of Magnolia fargesii, which is traditionally used in Asian medicine for treating headache and nasal congestion.

(-)-Fargesol is a nartural product from the flowers buds of Magnolia fargesii,the dried flower buds of M. fargesii, has been used as therapy for nasal empyema and headache.

6-Gingediol (compound 13) is a pungent component derived from ginger, noted for its potential antiserotonergic properties and protective effects on the gastric mucosa. Notably, 6-Gingediol exhibits no nasal irritation at concentrations below 10 μM, while significantly pronounced nasal irritation occurs at concentrations exceeding 100 μM and up to 1000 μM.
