Four new series of arctigenin derivatives were designed, synthesised, and evaluated for their anti-Toxoplasma gondii activity in vitro and in vivo. Among the synthesised compounds, 4-(3,4-dimethoxybenzyl)-3-(4-((1-(2-fluorobenzyl)-1H- 1,2,3-triazol-4-yl)methoxy)-3-methoxybenzyl)dihydrofuran-2(3H)-one (D4) exhibited the most potent anti-T. gondii activity and low cytotoxicity (IC50 in T. gondii: 17
设计,合成和评估了四个新系列的Arctigenin衍生物在体外和体内的抗弓形虫活性。在合成的化合物中,4-(3,4-二甲氧基苄基)-3-(4-((1-(2-氟苄基)-1 H -1,2,3-三唑-4-基)甲氧基)-3-甲氧基苄基)二氢呋喃-2(3 H ^) -酮(D4)显示出最有效的抗鼠弓形体的活性和低细胞毒性(IC 50在刚地弓形虫:17.1μM的IC 50在HeLa细胞中:≥600.0μM;选择性: 35.09),证明比引线化合物牛蒡苷元更好的结果(IC 50在T.弓形虫:586.4μM; HeLa细胞中的IC 50:572.7μM;选择性:0.98)和临床应用阳性对照药物螺旋霉素(IC 50在T. gondi:262.2μM; IC 50 0.72)::;在HeLa细胞中选择性189.0μM体外。此外,2-(4-((4-(3,4-二甲氧基苄基)-2-氧代四氢呋喃-3-基)甲基)-2-甲
