  Novel Carboxamide-Based Allosteric MEK Inhibitors: Discovery and Optimization Efforts toward XL518 (GDC-0973)

  摘要：

  The ERK/MAP kinase cascade is a key mechanism subject to dysregulation in cancer and is constitutively activated or highly upregulated in many tumor types. Mutations associated with upstream pathway components RAS and Raf occur frequently and contribute to the oncogenic phenotype through activation of MEK and then ERK. Inhibitors of MEK have been shown to effectively block upregulated ERK/MAPK signaling in a range of cancer cell lines and have further demonstrated early evidence of efficacy in the clinic for the treatment of cancer. Guided by structural insight, a strategy aimed at the identification of an optimal diphenylamine-based MEK inhibitor with an improved metabolism and safety profile versus PD-0325901 led to the discovery of development candidate 1-({3,4-difluoro-2-[(2-fluoro-4-iodophenyl)amino]phenyl}carbonyl)-3-[(2S)-piperidin-2-yl]azetidin-3-ol (XL518, GDC-0973) (1). XL518 exhibits robust in vitro and in vivo in preclinical models with sustained duration of action and is currently in early stage clinical trials. potency and efficacy in preclinical models with sustained duration of action and is currently in early stage clinical trials.

  unactivated monosubstituted, 1,1-disubstituted, and trisubstituted alkenes is disclosed. The reaction is notable in that it converts highly substituted alkenes, aryl bromides, and diboron reagents to products that contain a quaternary carbon and a synthetically versatile carbon-boron bond with control of stereoselectivity and regioselectivity. In addition, the method is demonstrated to be useful for the

  公开了一种未活化的单取代、1,1-二取代和三取代烯烃的Ni催化芳基硼化反应的方法。该反应的值得注意之处在于，它将高度取代的烯烃、芳基溴和二硼试剂转化为含有季碳和合成通用碳硼键的产物，并控制立体选择性和区域选择性。此外，该方法被证明可用于合成饱和氮杂环，这是药物化合物中的重要基序。最后，由于所表现出的不寻常的反应性，我们通过计算和实验技术研究了反应的机理细节。
