Abstact

Conversion of the proline-derived cyanamide lead to an acyclic cyanamide capable of forming an additional hydrogen bond with cathepsin K resulted in a large increase in inhibitory activity. An X-ray structure of a co-crystal of a cyanamide with cathepsin K confirmed the enzyme interaction. Furthermore, a representative acyclic cyanamide inhibitor 6r was able to attenuate bone resorption in the rat calvarial model.
