A series of novel, sterically hindered lipophilic analogs of AG 957 was designed and synthesized as potential protein tyrosine kinase (PTK) inhibitors. The in vitro activity, in vivo anti-leukemia activity, and pharmacology of these PTK inhibitors were studied. Some aspects of the structure-activity relationship associated with the carboxylic acid, phenol ring, and linker modifications are discussed
设计并合成了一系列新型的,空间受限的AG 957亲脂性类似物,作为潜在的蛋白酪氨酸激酶(PTK)抑制剂。研究了这些PTK抑制剂的体外活性,体内抗白血病活性和药理作用。讨论了与羧酸,苯酚环和连接基修饰相关的结构活性关系的某些方面。我们已经证明1,4-氢醌部分对于活性是必不可少的,并且位阻酯有助于增强体内功效。Adaphostin(NSC 680410)已作为改良的化合物出现,具有最大的体内抗白血病中空纤维活性,与最初的铅化合物AG 957一致。目前,adaphostin正在临床前毒理学研究中。
