  Structure-Activity Relationships in a Series of 5-[(2,5-Dihydroxybenzyl)amino]salicylate Inhibitors of EGF-Receptor-Associated Tyrosine Kinase: Importance of Additional Hydrophobic Aromatic Interactions

  摘要：

  Potent inhibitors of EGF-dependent protein tyrosine kinase (PTK) activity were synthesized in a series of 5-[(2,5-dihydroxybenzyl)amino]salicylates. Several of these compounds inhibited EGF-dependent DNA synthesis in ER 22 cells with IC50 < 1 muM. In this series of PTK inhibitors, the role of the salicylate moiety as a potential divalent ion chelator was tested and found to be nonessential in all cases. The length and ramification of the substituting carboxyl group were investigated to improve cellular bioavailability, and this analysis provided compounds with increased inhibitory effect on EGF-induced DNA synthesis. Salicylates esterified with long hydrophobic chains were shown to be noncompetitive inhibitors of ATP, in contrast to the free acid and methyl salicylate. Moreover, all the tested inhibitors were shown to be noncompetitive inhibitors of the peptide substrate. Structure-activity relationships allowed us to suspect a hydrophobic pocket in the tyrosine kinase domain, preferentially interacting with aromatic rings. Finally, the selectivity of the best inhibitors was tested against other kinases, and they were found to be selective for tyrosine kinase. They were also shown to be good inhibitors of EGF-receptor autophosphorylation.

  organometallic chemists is the direct functionalization of the bonds most recurrent in organic molecules: C-H, C-C, C-O, and C-N. An even grander challenge is C-C bond formation when both precursors are of this category. Parallel to this is the synthetic goal of achieving reaction selectivity that contrasts with conventional methods. Electrophilic aromatic substitution (EAS) via Friedel-Crafts acylation

  有机金属化学家的一个主要目标是将有机分子中最常见的键直接官能化：CH、CC、CO 和 CN。当两种前体都属于此类时，更大的挑战是 CC 键的形成。与此并行的是实现与传统方法形成对比的反应选择性的合成目标。通过 Friedel-Crafts 酰化的亲电芳香取代 (EAS) 是合成芳基酮的最著名方法，芳基酮是许多药物、农用化学品、香料、染料和其他商品化学品的常见结构基序。然而，只有当所需的酰化位点与反应的电子控制区域选择性一致时，EAS 合成策略才有效。在此，我们报告了空间控制的区域选择性芳烃酰化与水杨酸酯通过铱催化获得明显取代的二苯甲酮。实验和计算数据表明，一种独特的反应机制将 CO 活化和 CH 活化与单一铱催化剂相结合，无需外源氧化剂或碱。我们公开了对芳烃和酯成分的合成范围的广泛探索，最终以简明的合成强效抗癌剂羟基苯司他汀。
