Interleukins are a group of cytokines (secreted proteins and signaling molecules) that were first seen to be expressed by white blood cells (leukocytes). The function of the immune system depends in a large part on interleukins, and rare deficiencies of a number of them have been described, all featuring autoimmune diseases or immune deficiency. The majority of interleukins are synthesized by helper CD4 T lymphocytes, as well as through monocytes, macrophages, and endothelial cells. They promote the development and differentiation of T and B lymphocytes, and hematopoietic cells. Interleukin receptors on astrocytes in the hippocampus are also known to be involved in the development of spatial memories in mice.

Cat. No. Product Name CAS No. Information



LMT-28 (LMT28) is a specific blocker of IL-6 signaling via inhibits IL-6Rβ (gp130) with IC50 of 5.9 uM (IL-6–induced luciferase activity), selectively inhibits IL-6–induced phosphorylation of STAT3, JAK2, and gp130; does not affect LIF-induced STAT3 activation and not inhibit IL-11 stimulation on HepG2 cells; binds directly and specifically to gp130, and thereby inhibits the interaction of gp130 with the IL-6/IL-6Rα complex; inhibits IL-6–induced proliferation of the human erythroleukemic cell line TF-1 with IC50 of 7.5 uM; inhibits IL-6–induced TNF-α production, ameliorates the progression of pancreatitis in mice.


YM 90709


A potent IL-5 receptor antagonist that inhibits the binding of IL-5 to its receptor on peripheral human eosinophils and butyric acid-treated eosinophilic HL-60 clone 15 cells with IC50 of 1.0 and 0.57 uM, respectively; inhibits IL-5-prolonged eosinophil survival with IC50 of 0.45 uM and does not affect the GM-CSF-prolonged eosinophil survival; inhibits antigen-induced infiltration of eosinophils and lymphocytes into the bronchoalveolar lavage fluid (BALF) in BN rats (EC50=0.32 mg/kg and 0.12 mg/kg, respectively).


SP 4206


SP 4206 is a high-affinity (Kd=70 nM) small molecule that blocks blocks the binding of the IL-2α receptor (IL-2Rα) to IL-2; targets virtually the same critical "hot-spot" residues on IL-2 that drive binding of IL-2Rα.


Suplatast tosilate


Suplatast tosilate is a cytokine inhibitor that attenuates IL-2, IL-5 and IL-13 production and has no effect on IFN-γ production; suppresses IgE production, eosinophil infiltration and histamine release; exhibits antiasthmatic, anti-inflammatory and antifibrotic activity in vivo and is orally active.
