  Irreversible Inhibition of Epidermal Growth Factor Receptor Activity by 3-Aminopropanamides

  摘要：

  Irreversible epidermal growth factor receptor (EGFR) inhibitors contain a reactive warhead which covalently interacts with a conserved cysteine residue in the kinase domain. The acrylamide fragment, a commonly employed warhead, effectively alkylates Cys797 of EGFR, but its reactivity can cause rapid metabolic deactivation or nonspecific reactions with off-targets. We describe here a new series of irreversible inhibitors containing a 3-aminopropanamide linked in position 6 to 4-anilinoquinazoline or 4-anilinoquinoline-3-carbonitrile driving portions. Some of these compounds proved to be as efficient as their acrylamide analogues in inhibiting EGFR-TK (TK = tyrosine kinase) autophosphorylation in A549 lung cancer cells. Moreover, several 3-aminopropanamides suppressed proliferation of gefitinib-resistant H1975 cells, harboring the T790M mutation in EGFR, at significantly lower concentrations than did gefitinib. A prototypical compound, N-(4-(3-bromoanilino)quinazolin-6-yl)-3-(dimethylamino)propanamide (5), did not show covalent binding to cell-free EGFR-TK in a fluorescence assay, while it underwent selective activation in the intracellular environment, releasing an acrylamide derivative which can react with thiol groups.

• Dual irreversible kinase inhibitors: Quinazoline-based inhibitors incorporating two independent reactive centers with each targeting different cysteine residues in the kinase domains of EGFR and VEGFR-2

  function as dual irreversible inhibitors of the kinase domains of both Epidermal Growth Factor Receptor (EGFR) and Vascular Endothelial Growth Factor Receptor-2 (VEGFR-2) where each reactive center targets a different, non-conserved, cysteine residue located in the ATP binding pocket of these enzymes. The compounds contain a 6-(4-(dimethylamino) crotonamide) Michael acceptor group that targets Cys-773

  制备了一系列4-二甲氨基-丁-2-烯酸[4-（3，6-二氧代-环己-1，4-二烯基氨基）-7-乙氧基-喹唑啉-6-基]-酰胺衍生物。这些化合物有两个独立的反应中心，被设计为表皮生长因子受体（EGFR）和血管内皮生长因子受体2（VEGFR-2）激酶结构域的双重不可逆抑制剂，其中每个反应中心靶向不同的，位于这些酶ATP结合口袋中的非保守半胱氨酸残基。所述化合物包含靶向EGFR中的Cys-773的6-（4-（二甲基氨基）巴豆酰胺）迈克尔受体基团和靶向VEGFR-2中的Cys-1045的4-（氨基-[1,4]苯醌）部分。体外研究表明，这些化合物大多数是每种酶的相对有效抑制剂。将这些抑制剂与缺少一个或两个反应中心的参考化合物进行了比较。IC（50）值对测定中所用ATP浓度的相对依赖性表明，这些化合物似乎起每种激酶的不可逆抑制剂的作用。
