the salicylsulfonyl nitrostyryl 30, and our recently reported salicyl-containing stilbene 7. Taking compound 7 and the isomeric 8 as lead structures, bicyclic nuclei 9-12 were prepared as conformationally constrained mimetics in which the hydroxyphenyl rings of 7 and 8 are held coplanar with the stilbene ethylene bridge. A similar approach with styryl-based PTK inhibitors of structure 1 previously
在几种有效的蛋白-酪氨酸激酶(PTK)抑制剂中,水杨酸基团占主导地位,其中包括发酵产物lavendustin A(3),水杨基磺酰基亚硝基苯乙烯30和我们最近报道的含水杨基二苯乙烯7。将化合物7和异构体8作为作为构象受限的模拟物,制备了铅结构双环核9-12,其中7和8的羟苯基环与二苯乙烯乙烯桥共面。用结构1的基于苯乙烯基的PTK抑制剂的类似方法先前产生具有增强的效力的类似物2。然而,在当前情况下,当对免疫沉淀的p56lck PTK制剂的自磷酸化进行检查时,所得的含水杨基双环化合物显示出极差的抑制效能。
