Highly active, small-molecule furin inhibitors are attractive drug candidates to fend off bacterial exotoxins and viral infection. Based on the 22-residue, active Lys fragment of the mung bean trypsin inhibitor, a series of furin inhibitors were designed and synthesized, and their inhibitory activity toward furin and kexin was evaluated using enzyme kinetic analysis. The most potent inhibitor, containing 16 amino acid residues with a Ki value of 2.45×10~(-9) M for furin and of 5.60×10~(-7) M for kexin, was designed by three incremental approaches.
