• Synthesis, Structure and In Vitro Anti-Trypanosomal Activity of Non-Toxic Arylpyrrole-Based Chalcone Derivatives

  With an intention of identifying chalcone derivatives exhibiting anti-protozoal activity, a cohort of relatively unexplored arylpyrrole-based chalcone derivatives were synthesized in moderate to good yields. The resultant compounds were evaluated in vitro for their potential activity against a cultured Trypanosoma brucei brucei 427 strain. Several compounds displayed mostly modest in vitro anti-trypanosomal activity with compounds 10e and 10h emerging as active candidates with IC50 values of 4.09 and 5.11 µM, respectively. More importantly, a concomitant assessment of their activity against a human cervix adenocarcinoma (HeLa) cell line revealed that these compounds are non-toxic.

  为了确定具有抗原虫活性的蒲公英素衍生物，合成了一系列相对未被探索的基于芳基吡咯烯的蒲公英素衍生物，产率在中等到良好之间。所得化合物在体外评估其对培养的布鲁氏锥虫427株的潜在活性。几种化合物显示出主要是适度的体外抗锥虫活性，其中化合物10e和10h 显示出活性，IC50值分别为4.09和5.11微摩尔。更重要的是，对它们在人宫颈腺癌（HeLa）细胞系中的活性进行同时评估表明这些化合物无毒。
• Synthese de pyrroles et d'oxazoles par pyrolyse de N-(hydroxy-2′ ethyl) amino-3 propenoate
  作者：Catherine Pale-Grosdemange、Josselin Chuche

  DOI：10.1016/s0040-4020(01)81018-8

  日期：1989.1

  pyrolysis of various N-(2′-hydroxyethyl)-3-amino propenoates 1–6 and N-(2′-hydroxy-2′-phenyl ethyl)-3-amino propenoate 7–9 at 390°–420°C leads respectively to formylpyrroles 11–16 and benzoylpyrroles 17–19 and, in some cases, to substituted oxazoles 36–39. The results are best explained by the intermediate formation of dicarbonyl derivative followed either by an intramolecular thermal crotonisation

  各种N-（2'-羟基乙基）的气体热解PHAS -3-氨基propenoates 1 - 6和N-（2'-羟基-2'-苯基乙基）-3-氨基丙烯酸7 - 9在390℃-420 ℃，引线分别formylpyrroles 11 - 16和benzoylpyrroles 17 - 19，并且在一些情况下，为了取代的恶唑36 - 39。通过中间形成二羰基衍生物，然后在分子内进行热巴豆化反应或将偶氮甲ine叶立德分子进行6π电环化，可以最好地解释该结果。
