Lipopolysaccharides (LPS), derived from Escherichia coli O55:B5, are essential components of the outer membrane of Gram-negative bacteria. Composed of lipid A, a core oligosaccharide, and an O-specific polysaccharide, LPS exhibits strong immunogenicity. It activates immune cells via the TLR4 receptor, induces chemotactic cell migration and cytokine secretion, and helps maintain the integrity of the bacterial outer membrane, protecting against bile salts and lipid-based antibiotics. LPS is commonly used to establish inflammatory models, including arthritis, chronic obstructive pulmonary disease (COPD), acute respiratory distress syndrome (ARDS), and gastrointestinal disease models.

It can induce innate immune responses in mammals and serve as a vaccine adjuvant to enhance both innate and adaptive immunity, while modulating the tumor microenvironment and directly inducing apoptosis in cancer cells. Poly(I:C) is commonly used to establish acute respiratory distress syndrome (ARDS) animal models for studying immune responses and disease mechanisms.

Dazostinag disodium (TAK-676) is a synthetic novel interferon gene (STING) agonist that triggers STING signaling pathway activation and type I interferon activation. Dazostinag disodium (TAK-676) is also a highly effective immune system modulator with complete resolution and lasting memory of T cell immunity and the ability to promote lasting interferon-dependent anti-tumor immune responses.

4-Hydroxy-3-Nitrophenyl Acetate-KLH is a hapten-protein conjugate serving as a carrier protein for immunological studies. 4-Hydroxy-3-Nitrophenyl Acetate-KLH facilitates the generation of hapten-specific immune responses and is frequently employed to investigate antibody production, antigen presentation, and immune system activation mechanisms.

Cot inhibitor-1 is a selective inhibitor of Cot protein kinase (also known as Tpl2 or MAP3K8) (IC50 at 28 nM). Cot inhibitor-1 inhibited TNF-alpha production in human whole blood with IC50 of 5.7 nM. Cot is involved in a variety of cellular signaling pathways, particularly those involved in inflammation and immune responses. Cot inactivate-1 inhibits Cot activity and may have potential therapeutic effects on rheumatoid arthritis, inflammatory bowel disease and some types of cancer.

TASP 0277308 is a selective and potent inhibitor of sphingosine 1-phosphate receptor 1 ( S1P1) with immunomodulatory and anticancer activity that inhibits S1P- as well as VEGF-induced cellular responses and blocks VEGF-induced tube formation. TASP 0277308 is used in the study of immune and cardiovascular disorders.

STING agonist-30 is a potent activator of STING-dependent immune responses, demonstrating broad-spectrum antiviral effects against viruses such as HSV (Herpes Simplex Virus), rotavirus, and SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2).

Histamine (Ergamine) is an amine derived from histamine through enzymatic decarboxylation; it acts as a histamine receptor agonist and vasodilator. Histamine is an organic nitrogen compound that participates in local immune responses and regulates intestinal physiological functions. Histamine is a potent stimulant of gastric secretion, a bronchoconstrictor, a vasodilator, and a centrally acting neurotransmitter. Histamine influences the p38 MAPK/Akt signaling pathway and exhibits antitumor, antioxidant, and anti-inflammatory activities. Histamine can be used in research on acute myeloid leukemia, malignant melanoma, and renal cell carcinoma.

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.

Inosine pranobex (Delimmun) has a number of immunomodulatory effects, including inducing T-lymphocyte differentiation, augmenting macrophage and NK cell functions, and stimulating IL-2 production. Through these effects and others, isoprinosine shows antiviral activity and has applications against subacute sclerosing panencephalitis. It also restores depressed immune responses in Y patients after irradiation and reduces the incidence of infection in leukemia patients undergoing chemotherapy. It is most commonly used to treat the rare measles complication subacute sclerosing panencephalitis in conjunction with intrathecal interferon therapy.
