The Pyrazolo[1,5-a]pyrimidine derivatives represented by formula I and their pharmaceutically acceptable salts exhibit excellent kinase inhibiting activity. Drugs comprising the compounds as effective ingredients are therefore expected to be useful as therapeutic or prophylactic agents for a protein kinase mediated disorder in which kinase is implicated, such as inflammatory disease, autoimmune disease, destructive bone disorder, cancer and/or tumour growth.
公式I所代表的
吡唑并[1,5-a]
嘧啶衍
生物及其药学上可接受的盐具有出色的激酶抑制活性。因此,含有这些化合物作为有效成分的药物预计可用于治疗或预防与激酶有关的蛋白质激酶介导的疾病,如炎症性疾病、自身免疫性疾病、破坏性骨病、癌症和/或肿瘤生长。
