ovalbumin-sensitized

Nesosteine Lithium is a novel mucoregulatory that inhibits Herxheimer microconvulsions in guinea pigs and inhibits ovalbumin-induced histamine release from sensitized trachea.Nesosteine Lithium protects against ovalbumin-induced bronchospasm but is ineffective against histamine- and acetylcholine-induced bronchospasm. Nesosteine Lithium protected against ovalbumin-induced bronchospasm but not histamine- and acetylcholine-induced bronchospasm.

1. Narirutin (Naringenin-7-O-rutinoside) has antiproliferative property. 2. Narirutin has anti-oxidant property. 3. Narirutin has anti-allergic and anti-inflammatory properties , can reduce airway inflammation in ovalbumin (OVA)-sensitized / challenged NC / Nga mice , a model of allergic eosinophilic airway inflammation.

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.

TAS 205 is an inhibitor of hematopoietic prostaglandin D synthase (H-PGDS; IC50= 55.8 nM).1It is selective for H-PGDS over lipocalin-type PGDS (L-PGDS) at 100 μM, as well as over enzyme and receptor panels at 10 μM. TAS 205 inhibits production of prostaglandin D2induced by A23187 in KU812 human and RBL-2H3 rat basophils with IC50values of 78.3 and 181.3 nM, respectively. It inhibits ovalbumin-induced nasal lavage fluid eosinophil infiltration and late-phase nasal obstruction in an ovalbumin-sensitized guinea pig model of allergic rhinitis when administered at a dose of 30 mg/kg. 1.Aoyagi, H., Kajiwara, D., Tsunekuni, K., et al.Potential synergistic effects of novel hematopoietic prostaglandin D synthase inhibitor TAS-205 and different types of anti-allergic medicine on nasal obstruction in a Guinea pig model of experimental allergic rhinitisEur.

Theophylline-d6 is intended for use as an internal standard for the quantification of theophylline by GC- or LC-MS. Theophylline is an inhibitor of phosphodiesterase. It is also an adenosine A1 and A2 receptor antagonist. Theophylline induces relaxation of isolated cat bronchial smooth muscle segments precontracted with acetylcholine. It inhibits ovalbumin-induced increases in bronchoalveolar lavage fluid (BALF) eosinophil infiltration in an ovalbumin-sensitized mouse model of allergic asthma. Formulations containing theophylline have been used in the treatment of asthma and chronic obstructive pulmonary disease (COPD).

Diprovocim-1 is an agonist of the toll-like receptor 1/2 heterodimer.1It induces TNF-α release in THP-1 cells (EC50= 110 pM), an effect that can be inhibited by anti-TLR1 or anti-TLR2 antibodies. Diprovocim-1 (10 mg/kg) increases the production of ovalbumin-specific IgG1 in wild-type, but notTLR2-/-, mice sensitized to ovalbumin.2It also enhances anti-PD-L1 antibody-induced activation of cytotoxic T lymphocytes, reduction of tumor growth, and increases in survival in a B16/F10 murine melanoma model. 1.Morin, M.D., Wang, Y., Jones, B.T., et al.Diprovocims: A new and exceptionally potent class of toll-like receptor agonistsJ.

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.

Isonaringin exhibits anti-Alzheimer’s activity by inhibiting acetylcholinesterase (AChE).

Theophylline (1,3-Dimethylxanthine) sodium glycinate is a potent phosphodiesterase (PDE) inhibitor that targets PDE3 to relax airway smooth muscle and is used in asthma and chronic obstructive pulmonary disease (COPD) research. It also functions as an adenosine receptor antagonist, histone deacetylase (HDAC) activator, and exhibits anti-inflammatory activity by increasing IL-10 levels and inhibiting NF-κB nuclear import, while inducing apoptosis [1] [2] [3] [4] [5].

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.
