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 inhibits 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 the 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.
