An aminoisoindol was identified as P1 group by crystallographic fragment screening with the proprotein convertase furin, which enabled the design of peptidic inhibitors with inhibition constants <10 pM. Crystal structures in complex with furin confirmed the expected binding mode. The inhibitors showed significant antiviral activity against RSV and a furin-dependent influenza A virus.
