The present invention provides small molecules having high affinity to the ATP binding site of protein kinases, which are conjugated to apeptide or peptidomimetic moiety which mimics the substrate of PKB. The chimeric compounds according to the present invention preferably serve as PKB inhibitors with improved activity and selectivity. Novel ATP mimetic compounds, particularly isoquinoline derivatives, conjugated with peptides or peptidomimetics are useful as inhibitors of protein kinases for experimental, medical, and drug design purposes. Furthermore, pharmaceutical compositions comprising these protein kinase inhibitors, and methods of using such compositions for treatment and diagnosis of cancers, diabetes, cardiovascular pathologies, hemorrhagic shock, obesity, inflammatory diseases, diseases of the central nervous system, and autoimmune disease, are disclosed.
本发明提供了具有高亲和力与蛋白激酶的ATP结合位点结合的小分子,这些小分子与模拟PKB底物的肽或肽类似物结合。根据本发明的嵌合化合物优选作为具有改进活性和选择性的PKB抑制剂。新型ATP类似物化合物,特别是异喹啉衍生物,与肽或肽类似物结合,可用作蛋白激酶的抑制剂,用于实验、医学和药物设计目的。此外,包括这些蛋白激酶抑制剂的药物组合物,以及使用这些组合物用于治疗和诊断癌症、糖尿病、心血管病变、出血性休克、肥胖症、炎症性疾病、中枢神经系统疾病和自身免疫疾病的方法也被揭示。
