A peptidyl derivative structurally based on the inhibitory center of cystatin C inhibits bone resorption in vitro
Human cystatin C is a cysteine proteinase inhibitor belonging to the cystatin superfamily, which previously has been shown to inhibit bone resorption in bone organ culture. The aminoterminal segment, Arg8-Leu9-Val10-Gly11 (RLVG), of the single polypeptide chain of cystatin C constitutes an essential part of its inhibitory center. In the present study, the effect of benzyloxycarbonyl-Arg8-Leu9-Val1
