drugs is important because the current treatments show limited effectiveness and high toxicity. In this work, eighteen dihydrobenzofuran-type neolignans (DBNs) and two benzofuran-type neolignans (BNs) were synthesized and evaluated against amastigote forms of two Trypanosoma cruzi strains. The in vitro cytotoxicity and hemolytic activity of the most active compounds were also evaluated and their relationships
南美锥虫病是一种被忽视的热带病,影响超过 800 万人。尽管有针对这种疾病的治疗方法,但寻找新药很重要,因为目前的治疗效果有限且毒性高。在这项工作中,合成了十八种二氢苯并呋喃型新木脂素 (DBN) 和两种苯并呋喃型新木脂素 (BN),并针对两种克氏锥虫菌株的无鞭毛体形式进行了评估。还评估了最活跃化合物的体外细胞毒性和溶血活性,并通过计算机方法研究了它们与克氏锥虫微管蛋白 DBN 的关系。四种 DBN 表现出对 T. cruzi Tulahuen lac-Z 菌株的活性(IC50 从 7.96 到 21.12 µM),而 DBN 1 对 T. cruzi Y 菌株的无鞭毛体形式表现出最高活性(IC50 3.26 μM)。化合物 1-4 的 CC50 值高于抗锥虫活性,DBN 3 除外。所有具有抗锥虫活性的 DBN 均显示 CH50 高于 100 µM。计算机模拟结果表明,DBN 1、2 和 4
