9YIC - PubMed Abstract: 
A novel series of inhibitors of the interaction of IL-17A with its cognate receptor has been discovered using DNA-encoded library (DEL) technology. The lead compound (JNJ627, Compound 1 ) of the series occupies the interior interface of the IL-17A homodimer and disables receptor binding. The mechanism of action involves allosteric disruption of the IL-17A quaternary structure to prevent adoption of the receptor-binding conformation, rather than direct orthosteric inhibition at the receptor-binding site. Molecules of this series exhibit remarkably slow on-rate kinetics and potent inhibition of IL-17A signaling in human primary cells.
