  Optimizing the Physicochemical Properties of Raf/MEK Inhibitors by Nitrogen Scanning

  摘要：

  Substituting a carbon atom with a nitrogen atom (nitrogen substitution) on an aromatic ring in our leads 1 la and 13g by applying nitrogen scanning afforded a set of compounds that improved not only the solubility but also the metabolic stability. The impact after nitrogen substitution on interactions between a derivative and its on- and off-target proteins (Raf/MEK, CYPs, and hERG channel) was also detected, most of them contributing to weaker interactions. After identifying the positions that kept inhibitory activity on HCT116 cell growth and Raf/MEK, compound I (CH5126766/RO5126766) was selected as a clinical compound. A phase I clinical trial is ongoing for solid cancers.

  Transformation of N‐alkylated anilines to N‐aryloxamates was studied using ethyl 2‐diazoacetoacetate as an alkylating agent and dirhodium tetraacetate (Rh2(OAc)4) as the catalyst. The general applicability of the reaction as a synthetic method for N‐aryloxamates was studied with a number of substituted N‐alkylated anilines. The results revealed that the oxamate was formed by a radical reaction with

  研究了将N-烷基化苯胺转化为N-芳基草酸酯的方法，研究方法是使用2-重氮乙酰乙酸乙酯作为烷基化剂，并用四乙酸二钠（Rh 2（OAc）4）作为催化剂。用许多取代的N-烷基化苯胺研究了该反应作为N-芳基草酸酯的合成方法的一般适用性。结果表明草酸盐是通过与分子O 2和Rh 2（OAc）4作为引发剂的自由基反应形成的。
