The synthesis, cytotoxicity, anti-leishmanial and anti-trypanosomal activities of twelve triclosan-caffeic acid hybrids are described herein. The structure of the synthesized products was elucidated by a combination of spectrometric analyses. The synthesized compounds were evaluated against amastigotes forms of L. (V) panamensis, which is the most prevalent Leishmania species in Colombia, and against
本文描述了十二种三氯生-咖啡酸杂种的合成,细胞毒性,抗利什曼蛋白和抗锥虫活性。通过光谱分析的组合阐明了合成产物的结构。所合成的化合物对的无鞭毛体形式的评价L.(V)panamensis,这是最普遍的利什曼原虫在哥伦比亚物种,以及对克氏锥虫,这是致病物种给人类。评价了对人U-937巨噬细胞的细胞毒性。八种化合物对潘氏L.(V)具有活性(18–23、26和30),其中八种对克氏锥虫(19–22 )具有活性,24和28 – 30)的EC 50值低于40μM。化合物19-22,24和28-30表现出比苄硝唑(BNZ)更高的活动。酯19和21分别对巴拿马乳杆菌和克氏锥虫的活性最高,分别为3.82和11.65μM,以及8.25和8.69μM。化合物19-22,24和28-30表现出比苄硝唑(BNZ)更高的活动。大多数化合物显示出抗原虫活性,并与异常的18,26[ 28]和其余的化合物对哺乳动物细胞有毒
