engaged in therapeutic intervention against a number of proliferative diseases, we have discovered the 2-aminopyrido[2, 3-d]pyrimidin-7(8H)-ones as a novel class of potent, broadly active tyrosine kinase (TK) inhibitors. An efficient route was developed that enabled the synthesis of a wide variety of analogues with substitution on several positions of the template. From the lead structure 2, a series
在从事针对许多增生性疾病的治疗干预时,我们发现了2-氨基吡啶并[2,3-d]嘧啶7(8H)-一类新型有效的,广泛活性的酪氨酸激酶(TK)抑制剂。开发了一种有效的途径,该途径使得能够合成多种类似物,并在模板的多个位置上进行取代。由铅结构2,制得一系列在C-2位带有可变取代基和在N-8位带有甲基或乙基的类似物。该系列化合物可与ATP竞争,并且对包括受体(血小板衍生的生长因子,PDGFr,成纤维细胞生长因子,FGFr,表皮生长因子,EGFr)和非受体(c-Src)在内的一系列TK表现出亚微摩尔至低纳摩尔的效能)类。评估更充分的成员之一是63,IC50值分别为0.079 microM(PDGFr),0.043 microM(bFGFr),0.044 microM(EGFr)和0.009 microM(c-Src)。在细胞研究中,许多细胞系中有63种抑制PDGF介导的受体自身磷酸化,IC50值为0
