Description
Z-Phe-Tyrosinal is a potent and selective cathepsin L inhibitor. In the pit formation assay with unfractionated rat bone cells, 1.5 nM of Z-FY-CHO markedly inhibited parathyroid hormone-stimulated osteoclastic bone resorption. In ovariectomized mice, it suppressed at 2.5-10 mg/kg/day ip for four weeks bone weight loss dose-dependently.
