The synthesis and testing of potential multisubstrate inhibitors of tyrosine-specific protein kinases are described. One of the substrates, ATP, was mimicked by the known kinase inhibitor 5'-[4-(fluorosulfonyl)benzoyl]adenosine, which was covalently linked via the sulfonyl moiety to tyrosine mimics. The resulting multisubstrate inhibitors were tested for their ability to inhibit the transfer of phosphate
描述了酪氨酸特异性蛋白激酶潜在的多底物抑制剂的合成和测试。底物之一,ATP,是由已知的激酶抑制剂5'-[4-(氟磺酰基)苯甲酰基]腺苷模拟的,后者通过磺酰基部分与酪氨酸模拟物共价连接。测试了所得的多底物抑制剂通过p60v-abl抑制磷酸从ATP转移到蛋白质受体的能力,p60v-abl是由Abelson鼠白血病病毒(A-MuLV)的转化基因(v-abl)编码的酪氨酸激酶。尽管一系列抑制剂显示出中等强度的活性(IC50值低至19 microM),酪氨酸模拟物的修饰没有产生大的影响,这表明它们不作为多底物抑制剂起作用,而是主要通过所有抑制剂共有的腺苷部分结合。通过发现抑制剂缺乏特异性,在相当的浓度下抑制丝氨酸激酶的发现,加强了这种解释。
