Platycoside E (Platycodin E) is a platycodigenin-type saponin isolated from the root of Platycodon grandiflorum with haemolytic activity and adjuvant potential.

Ovalbumin is a protein extracted from egg white, synthesized in the fallopian tubes following estrogen or progesterone treatment, exhibiting hypotensive, antibacterial, anticancer, antioxidant, and immunomodulatory activities.

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.

Ovalbumin (154-159), a peptide fragment derived from ovalbumin, acts as a potent inhibitor of the angiotensin-converting enzyme (ACE) and is utilized in hypertension research [1] [2].

Ovalbumin (low endotoxin) is the predominant protein found in egg whites and exhibits various biological activities, including anti-cancer, antihypertensive, antibacterial, antioxidant, and immunomodulatory properties. Ovalbumin (low endotoxin) are synthesized as the most abundant protein in oviducts treated with progesterone or estrogen, and they are commonly used as markers in studies of hormone regulation on gene expression in tissues.

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.

OVA G4 peptide acetate(148274-82-2 free base) (SIIGFEKL acetate) is a variant of the agonist ovalbumin (OVA) peptide (257-264), SIINFEKL. OVA Peptide is a class I (Kb)-restricted peptide epitope of ovalbumin presented by the class I MHC (major histocompatibility complex) molecule, H-2Kb (class I genes of the mouse MHC).

RC529-MDP is an immunological adjuvant that couples Toll-like receptors (TLR4a) and NOD-like receptors (NOD2a) to enhance the innate immune response through the TLR4 and NOD2 signaling pathways. In mouse models, RC529-MDP induces high levels of the cytokine interleukin-related factor (IL-6), highlighting its immunostimulatory activity. Additionally, when injected into mice models with ovalbumin (OVA), RC529-MDP elevates OVA-specific antibody responses, T cell responses, and the proportion of memory T cells.

Lipid N2-3L is an ionizable cationic lipid with a pKa of 8.99, utilized in the formation of supramolecular lipid nanoparticles (SMLNPs) for enclosing mRNA in both in vitro and in vivo applications. Lipid N2-3L-containing SMLNPs accumulate at the injection site and draining lymph nodes in mice, featuring a luciferase reporter gene. Additionally, SMLNPs made with Lipid N2-3L that encapsulate ovalbumin mRNA and the Toll-like receptor 7/8 (TLR7/8) agonist R-848 serve as adjuvants. These enhance dendritic cell maturation and antigen presentation, reducing tumor volume and increasing survival rates in MC-38-OVA colon cancer mouse models.

Interleukin-2-inducible T cell kinase (ITK) is a non-receptor tyrosine kinase expressed in T cells, NKT cells and mast cells which plays a crucial role in regulating the T cell receptor (TCR), CD28, CD2, chemokine receptor CXCR4, and FcepsilonR-mediated signaling pathways. ITK inhibitors can be used for the treatment of inflammation and immune-mediated disorders. ITK inhibitor (N-[5-[[3-[(4-Acetylpiperazin-1-yl)carbonyl]-4-methyl-6-methoxy-phenyl]thio]thiazol-2-yl]-4-(N-1,2-dimethylpropylaminomethyl)benzamide) is the analogue of BMS-509744, which can potently and selectively inhibit Itk kinase activity. In vitro: BMS-509744 could reduce TCR-induced functions including PLCγ1 tyrosine phosphorylation, calcium mobilization, IL-2 secretion, and T-cell proliferation in vitro in both human and mouse cells [1]. In vivo: BMS-509744 suppressed the production of IL-2 induced by anti-TCR antibody administered to mice. BMS-509744 also significantly diminishes lung inflammation in a mouse model of ovalbumin-induced allergy/asthma [1]. Clinical trial: Up to now, both BMS-509744 and ITK inhibitor is still in the preclinical development stage.

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.

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.
