Compounds of general formula (1) are described: ##STR1## wherein Ar is an optionally substituted aromatic or heteroaromatic group; X.sup.1 is an oxygen or sulphur atom; R.sup.1 is a hydrogen atom or a methyl group; R.sup.2 is a hydrogen atom or a group --Alk.sup.1 or --X.sup.2 Alk.sup.1 where Alk.sup.1 is an optionally substituted aliphatic or heteroaliphatic group and X.sup.2 is a --C(O)--, --C(S)--, or --S(O).sub.n group where n is an integer 1 or 2; R.sup.3 is a hydrogen atom or a group --Alk.sup.2, \x9bwhere Alk.sup.2 is as defined for Alk.sup.1 !, --X.sup.2 Alk.sup.2, --Ar.sup.1 \x9bwhere Ar.sup.1 is an optionally substituted aromatic or heteroaromatic group!, --Alk.sup.2 Ar.sup.1, or --X.sup.2 Alk.sup.2 Ar.sup.1 ; and the salts, solvates, hydrates and N-oxides thereof. The compounds are selective inhibitors of the protein tyrosine kinase p56.sup.lck and are of use in the prophylaxis and treatment of immune diseases, hyperproliferative disorders and other diseases in which inappropriate p56.sup.lck activity is believed to have a role.
通式(1)描述了以下化合物:其中Ar是一个可选择取代的芳香或杂环芳基;X1是氧或硫原子;R1是氢原子或甲基基团;R2是氢原子或基团-Alk1或-X2Alk1,其中Alk1是一个可选择取代的脂肪或杂原子脂肪基团,X2是一个-C(O)-、-C(S)-或-S(O)n基团,其中n是整数1或2;R3是氢原子或基团-Alk2,其中Alk2如Alk1所定义!,-X2Alk2,-Ar1,其中Ar1是一个可选择取代的芳香或杂环芳基!,-Alk2Ar1或-X2Alk2Ar1;以及它们的盐、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.lck的选择性抑制剂,并且用于预防和治疗免疫性疾病、过度增殖性疾病和其他与不适当的p56.lck活性有关的疾病。
