Does not inhibit factor Xa. Publication Abstract from PubMed Flower power: Potent protease inhibitors containing triazolyl mimics of cis and trans backbone amides were engineered based on the structure of the sunflower trypsin inhibitor 1. The biologically relevant cis-Pro motif was successfully replaced with a non-prolyl unit. High-resolution crystal structures of 1,4- and 1,5-disubstituted 1,2,3-triazolyl peptidomimetics can serve in the design of tailor-made Bowman-Birk inhibitors.
