IL-15 Inhibitor

Ritlecitinib (PF-06651600) is a highly selective, orally active, irreversible covalent JAK3 inhibitor (IC₅₀=33 nM) without inhibitory activity towards JAK1, JAK2, and TYK2 (IC₅₀ >10 μ M). Ritlecitinib rapidly inactivates the JAK3 kinase, and blocks signaling and downstream STAT phosphorylation mediated by common gamma chain cytokines such as IL-2 and IL-15. Ritlecitinib can inhibit Th1/Th17 cell differentiation and function, and effectively suppress preclinical animal models such as alopecia areata, adjuvant-induced arthritis (AIA), and experimental autoimmune encephalomyelitis (EAE).

Elaidic acid is an orally active trans fatty acid. Elaidic acid enhances the stemness of colorectal cancer cells by activating the Wnt/ERK1/2 pathway, thereby promoting cell proliferation, invasion and metastasis, and inhibiting apoptosis. Elaidic acid also inhibits the growth of Lactobacillus and alters the cell surface hydrophobicity of Lactobacillus. Elaidic acid reduces basal 2-deoxyglucose uptake in muscle cells and adipocytes. Elaidic acid can be used in research on colorectal cancer, insulin and other related areas.

Ordesekimab (AMG 714; PRV-015) is a fully human IgG1κ anti-IL-15 (Interleukin Related) monoclonal antibody. The binding of Ordesekimab to IL-15 inhibits the interaction of IL-15 with the IL-2Rβ and common γ chain of the IL-15 receptor complex, but not with the IL-15Rα chain. Ordesekimab has the potential for study of nonresponsive celiac disease (NRCD).

Y-320 is a potent, orally active phenylpyrazoleanilide immunomodulator. Y-320 inhibits IL-17 production by CD4 T cells stimulated with IL-15 with IC₅₀ values of 20 to 60 nM. Y-320 enhances TP53, DMD, and COL17A1 PTC readthrough by G418 and increases cellular protein levels and protein synthesis. Y-320 concomitants use of with a low dose of Paclitaxel (HY-B0015) significantly sensitized multidrug resistance (MDR) tumors by inducing G2/M phase arrest and apoptosis. Y-320 can be used for research of rheumatoid arthritis (RA) and cancer.

IL-15-IN-1 (compound 76) is a potent and selective Interleukin 15 (IL-15) inhibitor, inhibiting the proliferation of IL-15-dependent cells with an IC₅₀ of 0.8 μM.

HuMax-IL15 is a human IgG1 monoclonal antibody against IL-15. HuMax-IL15 is applicable to the research of rheumatoid arthritis. The recommended isotype control is human IgG1 kappa (HY-P99001).

Ritlecitinib (PF-06651600) tosylate is a highly selective, orally active, irreversible covalent JAK3 inhibitor (IC₅₀=33 nM) without inhibitory activity towards JAK1, JAK2, and TYK2 (IC₅₀ >10 μ M). Ritlecitinib tosylate rapidly inactivates the JAK3 kinase, and blocks signaling and downstream STAT phosphorylation mediated by common gamma chain cytokines such as IL-2 and IL-15. Ritlecitinib tosylate can inhibit Th1/Th17 cell differentiation and function, and effectively suppress preclinical animal models such as alopecia areata, adjuvant-induced arthritis (AIA), and experimental autoimmune encephalomyelitis (EAE).

Patiromer is an orally active, selective and non-absorbable intestinal potassium (K⁺) polymer binder that reversibly binds potassium ions in exchange for calcium (Ca²⁺). Patiromer can rapidly and continuously reduce serum potassium levels, maintain a normal blood potassium state, and reduce serum aldosterone levels. Patiromer also increases fecal potassium excretion. Patiromer is mainly used in the study of hyperkalemia associated with diseases such as chronic kidney disease, diabetes, and heart failure, and is particularly suitable for improving renin-angiotensin-aldosterone system inhibitor (RAASi) therapy.

Ritlecitinib (PF-06651600) malonate is a highly selective, orally active, irreversible covalent JAK3 inhibitor (IC₅₀=33 nM) without inhibitory activity towards JAK1, JAK2, and TYK2 (IC₅₀ >10 μ M). Ritlecitinib malonate rapidly inactivates the JAK3 kinase, and blocks signaling and downstream STAT phosphorylation mediated by common gamma chain cytokines such as IL-2 and IL-15. Ritlecitinib malonate can inhibit Th1/Th17 cell differentiation and function, and effectively suppress preclinical animal models such as alopecia areata, adjuvant-induced arthritis (AIA), and experimental autoimmune encephalomyelitis (EAE).
