Several series of hydroxybiphenyl compounds substituted by a hydrophobic group (tert-butyl or phenyl) and bearing a free or protected carboxylic moiety were synthesized. The compounds were tested for their ability to inhibit the intrinsic tyrosine protein kinase activity of the EGF-receptor in vitro and the EGF-stimulated DNA-synthesis by ER 22 cells. Although the compounds of each series had poor
合成了一系列被疏水基团(叔丁基或苯基)取代并带有游离或受保护的羧基部分的羟基联苯化合物。测试了这些化合物在体外抑制EGF受体固有的酪氨酸蛋白激酶活性和ER 22细胞抑制EGF刺激的DNA合成的能力。尽管每个系列的化合物在体外的抑制能力都很差(IC50 >> 100 microM),但是它们中的大多数以相对较低的剂量抑制了ER 22细胞的EGF依赖性细胞增殖(化合物14的IC50 = 1.1 microM)。基于细胞结果的结构活性研究表明,最有趣的系列是2'-羟基-1,1':4',1“-三苯基-4-羧酸酯的线性三联苯系列B。羟基的可用性,
