  Discovery of a Potent, Selective, and Orally Bioavailable c-Met Inhibitor: 1-(2-Hydroxy-2-methylpropyl)-N-(5-(7-methoxyquinolin-4-yloxy)pyridin-2-yl)-5-methyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazole-4-carboxamide (AMG 458)

  摘要：

  Deregulation of the receptor tyrosine kinase c-Met has been implicated in human cancers. Pyrazolones with N-1 bearing a pendent hydroxyalkyl side chain showed selective inhibition of c-Met over VEGFR2. However, studies revealed the generation of active, nonselective metabolites. Blocking this metabolic hot spot led to the discovery of 17 (AMG 458). When dosed orally, 17 significantly inhibited tumor growth in the NIH3T3/FPR-Met and U-87 MG xenograft models with no adverse effect on body weight.

  Dearomative photocycloadditions are valuable chemical transformations, serving as an efficient platform to create three-dimensional molecular complexity. However, the photolability of the original addition product especially within the context of ortho cycloadditions often causes undesired consecutive rearrangements, rendering these ortho cycloadducts elusive. Herein, we report an ortho-selective intermolecular

  脱芳烃光环加成是有价值的化学转化，可作为创建三维分子复杂性的有效平台。然而，原始加成产物的光不稳定性，尤其是在邻位环加成的情况下，通常会导致不需要的连续重排，从而使这些邻位环加合物难以捉摸。在此，我们通过利用应变释放方法报告了双环氮杂芳烃（包括（异）喹啉、喹唑啉和喹喔啉）的邻位选择性分子间光环加成。以双环 [1.1.0] 丁烷作为偶联伙伴，这种去芳香化 [2π + 2σ] 环加成可以直接构建 C(sp 3)-富含二环[2.1.1]己烷直接连接到N-杂芳烃。光物理实验和 DFT 计算揭示了 [2π + 2σ] 选择性的起源，并表明，除了最初提出的能量转移或直接激发途径外，链式反应机制根据反应条件起作用。
