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。
