With the aim of delineating the SAR associated with (I), fifty-five analogs were synthesized and screened against Mtb. The SAR suggests that the piperazine ring, benzyl urea and piperonyl moieties are essential signatures of this series. Active compounds in this series are metabolically stable, have low cellular toxicity and are valuable leads for optimization. Molecular docking suggests these molecules
摘要 GSK Tres Cantos 的科学家披露的N-糠基哌嗪脲被选为来自表型全细胞筛选的抗分枝杆菌。用苯环取代 GSK Tres Cantos 分子中的呋喃环产生的分子 ( I ) 对Mtb H37Rv 的 MIC 为 1 μM,细胞毒性低(HepG2 IC 50 ~ 80 μM),良好的 DMPK 特性和特异性山地车_ 为了描绘与 ( I ) 相关的 SAR,合成了 55 种类似物并针对Mtb进行了筛选. SAR 表明哌嗪环、苄基脲和胡椒基部分是该系列的基本特征。该系列中的活性化合物代谢稳定,细胞毒性低,是优化的宝贵线索。分子对接表明这些分子像 Q203 一样占据 QcrB 的 Q0 位点。 图形摘要 N-糠基哌嗪-1-羧酰胺的生物等排替代产生了分子 (I) 一种具有令人满意的 PD、代谢和毒性特征的新型先导。

The first example of direct reductive amination (DRA) of ketones with electron-deficient amines (EDA) such as Cbz-, Boc-, EtOCO-, Fmoc-, Bz-, ArSO2-, etc. protected amines have been achieved using catalytic Re2O7/NaPF6. Excellent chemoselectivities as well as diastereoselectivity (for 2-alkyl cyclohexanones) were obtained.

4‐Propylcatechol carbonate is a shelf‐stable, renewable C1 reactant. It is easily prepared from renewable 4‐propylcatechol (derived from wood) and dimethyl carbonate (derived from CO2) using a reactive distillation system. In this work, the 4‐propylcatechol carbonate is used for the two‐step synthesis of carbamates under mild reaction conditions. In the first step, 4‐propylcatechol carbonate is treated
