Inside Back Cover: Inhibition of Kallikrein‐Related Peptidases 7 and 5 by Grafting Serpin Reactive‐Center Loop Sequences onto Sunflower Trypsin Inhibitor‐1 (SFTI‐1) (ChemBioChem 8/2016)

Abstract

The inside back cover picture shows a rational peptide‐design approach for the development of inhibitors of the serine proteases kallikrein‐related peptidases 7 (KLK7) and 5 (KLK5). Hybrid peptides combining the scaffold of the bicyclic peptide sunflower trypsin inhibitor‐1 (SFTI‐1) with amino acid sequences derived from the reactive center loops of different serpins were generated by solid‐phase peptide synthesis. Some of these molecules displayed nanomolar protease inhibition, and it was demonstrated that selectivity towards KLK5 and KLK7 could be transferred from the irreversible protease inhibitors of the serpin family to reversible canonical inhibitors.
