Fused polycyclic 2-aminopyrimidines of formula (1): ##STR1## wherein Ar is an optionally substituted aromatic or heteroaromatic group; X is a carbon or nitrogen atom; Y is a carbon or nitrogen atom; Z is a linker group; A together with X and Y forms an optionally substituted monocyclic or bicyclic aromatic or heteroaromatic group; and the salts, solvates, hydrates and N-oxides thereof are described. The compounds are potent and selective inhibitors of the protein tyrosine kinases p56.sup.lck and p59.sup.fyn and are of use in the prophylaxis and treatment of immune diseases, hyperproliferative disorders and other diseases in which inappropriate p56.sup.lck and/or p59.sup.fyn activity is believed to have a role.
公式(1)的融合多环2-氨基嘧啶:其中Ar是一个可选择取代的芳香或杂环芳基;X是一个碳或氮原子;Y是一个碳或氮原子;Z是一个连接基团;A与X和Y一起形成一个可选择取代的单环或双环芳香或杂环芳基;以及其盐、溶剂合物、水合物和N-氧化物。这些化合物是蛋白酪氨酸激酶p56.sup.lck和p59.sup.fyn的有效选择性抑制剂,并且在预防和治疗免疫性疾病、高增殖性疾病以及其他疾病中具有作用,这些疾病中不适当的p56.sup.lck和/或p59.sup.fyn活性被认为起作用。
