The present invention relates to a novel class of compounds mainly, leucinamide-amino-carboxylate derivatives of formula (I) wherein Y is CR1R2, O, S, -SO2, C=0 or NR9; Z is CR1R2, O, S, -SO2, C=O or NR9 and each G is independently a CR1CR2. Said compounds are cathepsin cysteine protease inhibitors, including but not limited to, inhibitors of cathepsin K, L, S and B and to pharmaceutical compositions thereof. These compounds are useful for treating and preventing cathepsin dependent conditions in which inhibition of bone resorption is indicated, such as osteoporosis.
本发明涉及一种新型化合物类别,主要是公式(I)中的亮氨酰胺-氨基-羧酸衍生物,其中Y是CR1R2,O,S,-SO2,C=0或NR9; Z是CR1R2,O,S,-SO2,C=O或NR9,且每个G都是独立的CR1CR2。所述化合物是半胱氨酸蛋白酶卡特普西蛋白酶抑制剂,包括但不限于卡特普西蛋白酶K、L、S和B的抑制剂以及其制药组合物。这些化合物可用于治疗和预防卡特普西蛋白酶依赖性疾病,其中骨吸收抑制是指示的,例如骨质疏松症。
