Synthesis of a cytotoxic dihydrochalcone, first isolated from a traditional Amazonian medicinal plant Iryanthera juruensis Warb (Myristicaceae), followed by a comprehensive SAR analysis of saturated and unsaturated chalcone synthetic intermediates, led to the identification of analogues with selective and significant in vitro anti- Trypanosoma cruzi activity. Further SAR studies were undertaken with
合成具有细胞毒性的二氢查耳酮,首先从传统的亚马逊药用植物鸢尾菊中提取(Myristicaceae),然后对饱和和不饱和查耳酮合成中间体进行全面的SAR分析,从而鉴定出具有选择性和显着体外抗锥虫病的类似物。克鲁兹活动。通过合成21个含有两个烯丙氧基部分的新查耳酮进行了进一步的SAR研究,结果发现了2',4'-二烯丙氧基-6'-甲氧基查耳酮,在浓度低于25 microM时对这种寄生虫具有更高的选择性,其中四个表现出大于12的选择性指数。
