E2982 IFN alpha-IFNAR-IN-1 hydrochloride IFN alpha-IFNAR-IN-1 hydrochloride is a nonpeptidic, low-molecular-weight inhibitor that inhibits the interaction between IFN-α and IFNAR. This compound inhibits modified Vaccinia virus ankara (MVA)-induced IFN-α responses in murine bone-marrow-derived, Flt3-L-differentiated pDC cultures (BM-pDCs) with IC50 value of 2-8 μM.
S3827 Royal jelly acid Royal jelly acid (10-Hydroxy-trans-2-decenoic acid, 10H2DA) is the principal lipid component in royal jelly which is the food for queen and larvae honeybees. It is involved in several treatment processes of autoimmune and inflammatory diseases, including inhibition of lipopolysaccharide (LPS)- and interferon (IFN)-γ-stimulated macrophage responses, inhibition of T-cell proliferation and anti-rheumatoid activity.
S6494 CCCP CCCP (Carbonyl cyanide m-chlorophenyl hydrazone, Carbonyl cyanide 3-chlorophenylhydrazone), an oxidative phosphorylation inhibitor, is a protonophore mitochondrial uncoupler that increases membrane permeability to protons, leading to a disruption in the mitochondrial membrane potential. This compound, the protonophore, can inhibit STING-mediated IFN-β production via disrupting mitochondrial membrane potential (MMP).

S3924 Ginsenoside Rb1 Ginsenoside Rb1 (Gypenoside Ⅲ) is a protopanaxadiol that has diverse in vitro and in vivo effects, including neuroprotective, anti-inflammatory, and anti-obesity actions. This compound, a main constituent of the root of Panax ginseng, inhibits Na+, K+-ATPase activity with IC50 of 6.3±1.0 μM. It also inhibits IRAK-1 activation and phosphorylation of NF-κB p65. This chemical reduces the expressions of TLR3, TLR4 and TRAF-6, and down-regulates the levels of TNF-α, IFN-β and iNOS.

S5588 Creatine Creatine (Methylguanidoacetic acid) is a nitrogenous organic acid that occurs naturally in vertebrates. It facilitates the recycling of adenosine triphosphate (ATP) primarily in muscle and brain tissue. This compound can inhibit JAK-STAT1 signal transmission by inhibiting the interaction of IFN-γ receptors with JAK2 in an ATP-independent manner, thereby inhibiting downstream pro-inflammatory gene expression.
