BING, a antimicrobial peptide discovered in Japanese medaka fish (O. laptipes), originates from vacuolar protein sorting-associated protein 13D-like (Vps13D). It exhibits efficacy against a range of Gram-negative and Gram-positive bacteria, notably including methicillin-resistant S. aureus (MRSA; MICs = 4-64 µg/ml). Furthermore, BING enhances the effectiveness of antibiotics such as ampicillin, amoxicillin, and novobiocin against P. aeruginosa, and it prevents resistance development to kanamycin and ampicillin in E. coli. Notably, its administration in vivo significantly improves survival rates in O. laptipes challenged with E. tarda.

Apostatin-1 (Apt-1) is a novel TRADD inhibitor that binds to a pocket on the N-terminal TRAF2 binding domain of TRADD.

Corticosterone (Kendall's compound B) is an adrenocortical steroid with salocorticoid and glucocorticoid activity that is orally active. Corticosterone is involved in the regulation of energy, immune responses, and stress responses in the body.

Dexamethasone is a glucocorticoid receptor agonist and IL receptor modulator with anti-inflammatory, immunosuppressive, and apoptosis-inducing activities. It inhibits the production of inflammatory miRNA-155 exosomes in macrophages, significantly reduces inflammatory cytokine expression in neutrophils and monocytes, suppresses LPS-induced macrophage inflammation, and induces autophagy. It is commonly used to induce animal models of depression, muscle atrophy, and hypertension, and holds potential in COVID-19 research.

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.

Polyinosinic-polycytidylic acid (Poly(I:C)) is a synthetic double-stranded RNA (dsRNA) analog and an agonist of TLR3 as well as retinoic acid-inducible gene I (RIG-I) and melanoma differentiation-associated protein 5 (MDA5). 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.

JNK-IN-8 (JNK Inhibitor XVI) is an effective JNK inhibitor that inhibits JNK1, JNK2, and JNK3 with IC₅₀ values of 4.7, 18.7, and 1 nM, respectively. JNK-IN-8 offers the advantages of minimal off-target activity, sustained inhibition, and high specificity. JNK-IN-8 primarily acts by blocking the JNK/c-Jun signaling pathway, inhibiting the phosphorylation of the downstream transcription factor c-Jun, thereby regulating the expression of genes associated with inflammatory responses, apoptosis, and stress responses. JNK-IN-8 can be used in research on tumors, inflammation, and neurological diseases.

Atinvicitinib, a selective Janus kinase (JAK) inhibitor, demonstrates high specificity for Janus kinase 1 (JAK1), consequently inhibiting downstream cytokine signaling pathways that rely on JAK1 enzymatic activity. Atinvicitinib modulates a wide range of cytokines that are implicated in itch responses, allergic reactions, and inflammatory conditions, making it a significant research tool for studying cytokine-mediated immune processes as well as therapeutic modulation of allergic and inflammatory diseases.
