KCF-18
Immune Research only Animal studies
A synthetic peptide designed from the binding regions of cytokine receptors. It attaches to several inflammatory signals at once, including TNF-α and IL-6, and keeps them from reaching their receptors. In mice it reduced white blood cell infiltration and vascular inflammation.

How it works
Designed from the binding faces of cytokine receptors. It is charged and partly water-repelling, letting it grip several inflammatory signals at once — TNF-α and IL-6 among them — so they never reach their own receptors.
