N-terminal substituted dipeptide nitriles as defined are useful as inhibitors of cysteine cathepsins, e.g. cathepsins B, K, L and S, and can be used for the treatment of cysteine cathepsin dependent diseases and conditions, including inflammation, rheumatoid arthritis, osteoarthritis, osteoporosis, tumors (especially tumor invasion and tumor metastasis), coronary disease, atherosclerosis (including atherosclerotic plaque rupture and destabilization). Particular dipeptide nitriles are compounds of formula I, or physiologically-acceptable and -cleavable esters or a salts thereof
wherein: the symbols are as defined.
In particular it has been found that by appropriate choice of groups R, R2, R3, R4, R5, X1, Y and L, the relative selectivity of the compounds as inhibitors of the various cysteine cathepsin types, e.g. cathepsins B, K, L and S may be altered, e.g. to obtain inhibitors which selectively inhibit a particular cathepsin type or combination of cathepsin types.
N-末端取代二肽腈可作为半胱氨酸蛋白酶抑制剂,例如半胱氨酸蛋白酶B、K、L和S,并可用于治疗依赖于半胱氨酸蛋白酶的疾病和症状,包括炎症、类风湿关节炎、骨关节炎、骨质疏松、肿瘤(尤其是肿瘤侵袭和转移)、冠心病、动脉粥样硬化(包括动脉粥样硬化斑块破裂和不稳定)。特定的二肽腈化合物为公式I的化合物,或其生理上可接受和可裂解的酯或盐,其中:符号如定义。特别是发现通过适当选择基团R、R2、R3、R4、R5、X1、Y和L,可以改变化合物作为各种半胱氨酸蛋白酶类型抑制剂的相对选择性,例如半胱氨酸蛋白酶B、K、L和S,可改变,例如获得选择性抑制特定蛋白酶类型或蛋白酶类型组合的抑制剂。
