  Antimalarial Activity of Newly Synthesized Chalcone Derivatives In Vitro

  摘要：

  Twenty‐seven novel chalcone derivatives were synthesized using Claisen‐Schmidt condensation and their antimalarial activity against asexual blood stages of Plasmodium falciparum was determined. Antiplasmodial IC50 (half‐maximal inhibitory concentration) activity of a compound against malaria parasites in vitro provides a good first screen for identifying the antimalarial potential of the compound. The most active compound was 1‐(4‐benzimidazol‐1‐yl‐phenyl)‐3‐(2, 4‐dimethoxy‐phenyl)‐propen‐1‐one with IC50 of 1.1 μg/mL, while that of the natural phytochemical, licochalcone A is 1.43 μg/mL. The presence of methoxy groups at position 2 and 4 in chalcone derivatives appeared to be favorable for antimalarial activity as compared to other methoxy‐substituted chalcones. Furthermore, 3, 4, 5‐trimethoxy groups on chalcone derivative probably cause steric hindrance in binding to the active site of cysteine protease enzyme, explaining the relative lower inhibitory activity.

  由π共轭小分子-氧电荷转移态实现的选择性C(sp3)–H键有氧氧化

  摘要：

  由于芳烃和烯烃的高氧化电位，以前的苄基和烯丙基C-H氧化方法必须使用强氧化剂、金属催化剂或自由基引发剂（例如光催化剂或氢原子转移试剂）才能有效。在这里，我们利用氧产生三重自旋电荷转移态，π共轭化合物有效地进入芳烃的三重激发态，然后通过能量转移形成单线态氧，促进C-H键氧化。与以往的氧化不同，这是首次在不使用任何催化剂或添加剂的情况下选择性氧化一系列天然产物和药物分子（27个例子）。该转化可以在阳光下进行，产生有价值的不饱和（芳香）酮，并且只产生水作为废物，这符合绿色化学的12条原则中的每一项。

  Efficient and solvent-free copper-catalyzed N-arylations of imidazoles with aryl and heteroaryl halides have been demonstrated. In the presence of CuBr, 2-aminopyrimidine-4,6-diol, and TBAF (n-Bu4NF), a variety of imidazoles underwent the N-arylation reaction with aryl and heteroaryl halides smoothly in moderate to excellent yields. Noteworthy is that the reaction is conducted under solvent-free conditions
