  Development of Natural Product-Derived Receptor Tyrosine Kinase Inhibitors Based on Conservation of Protein Domain Fold

  摘要：

  Receptor tyrosine kinases (RTKs) such as Tie-2, IGF1R, Her-2/Neu, EGFR, and VEGFR1-3 play crucial roles in the control of cell growth and differentiation. Inhibition of such RTKs has become a major focus of current anticancer drug development, and therefore the discovery of new classes of inhibitors for these signal-transducing proteins is of prime importance. We have recently proposed a novel concept for improving the hit-finding process by employing natural products as biologically validated starting points in structural space for compound library development. In this concept, natural products are regarded as evolutionary chosen ligands for protein domains which are structurally conserved yet genetically mobile. Here we report on the discovery of novel and highly selective VEGFR-2 and -3, Tie-2, and IGF1R inhibitors derived from the naturally occurring Her-2/Neu kinase inhibitor nakijiquinone C and developed on the basis of this concept. Based on the structure of the natural product, a small library (74 members) was synthesized and investigated for inhibition of kinases with highly similar ATP-binding domains. The library yielded inhibitors with IC(50)s in the low micromolar range with high frequency (7 out of 74). In particular, four inhibitors of Tie-2 were found, a kinase critically involved in the formation of new blood vessels from preexisting ones (angiogenesis) and believed to be a new promising target in antitumor therapy. These results support the "domain concept". To advance the development of improved inhibitors, extensive molecular modeling studies were undertaken, including the construction of new homology models for VEGFR-2 and Tie-2. These studies revealed residues in the kinase structure which are crucial to the development of tailor-made receptor tyrosine kinase inhibitors.

  pro-inflammatory leukotrienes, is an attractive drug target for the pharmacotherapy of inflammatory and allergic diseases. Here, we present the discovery and biological evaluation of novel series of 1,4-benzoquinones and respective resorcinol derivatives that efficiently inhibit human 5-LO, with little effects on other human lipoxygenases. SAR analysis revealed that the potency of the compounds strongly depends

  5-脂氧合酶（5-LO）是一种催化促炎性白三烯生物合成初始步骤的酶，是炎性和过敏性疾病药物治疗的引人注目的药物靶标。在这里，我们介绍发现和生物学评估的新型系列的1,4-苯醌和各自的间苯二酚衍生物，可以有效抑制人5-LO，对其他人脂氧合酶的影响很小。SAR分析表明，化合物的效力在很大程度上取决于亲脂性残基的结构特征，其中庞大的萘基或二苯并呋喃部分有利于5-LO抑制。在1，4-苯醌中，化合物Ig 5-[（2-萘基）甲基] -2-羟基-2,5-环己二烯-1,4-二酮在用IC 50进行的无细胞分析中有效地阻断了5-LO活性。 ＝0.78μM，并抑制了多形核白细胞中5-LO产物的合成，IC 50  ＝2.3μM。分子对接研究表明，在5-LO中Ig有一个具体的结合位点，其中选定的π-π相互作用以及氢键相互作用实现了与酶活性位点的结合。总之，我们的研究揭示了新型有价值的5-LO抑制剂，它们有可能作为抗炎化合物进行进一步的临床前评估。
