series of new arctigenin derivatives were designed, synthesized and tested in our study. The anthelmintic activity of most of the derivatives ranged from 1 to 10 mg/L. Compared to traditional drug praziquantel (EC50 = 2.69 mg/L), ether derivatives 2g and 2h exhibited slightly higher anti-parasitic activity, with the EC50 values of 2.48 and 1.52 mg/L, respectively. Furthermore, the arctigenin-imidazole
为了控制中间D虫的寄生虫病,在我们的研究中设计,合成和测试了一系列新的arctigenin衍生物。大多数衍生物的驱虫活性为1至10 mg / L。与传统药物吡喹酮(EC 50 = 2.69 mg / L)相比,醚衍生物2g和2h表现出略高的抗寄生虫活性,EC 50值分别为2.48和1.52 mg / L。此外,牛蒡苷元咪唑杂种图4a和4b中也被除去D.中间型有效地,与EC 50值分别为2.13和2.07 mg / L。结构-活性关系分析表明,连接基和咪唑取代基的四个碳原子长度可以显着提高驱虫活性,并降低毒性。通过扫描电子显微镜观察,化合物4a和4b引起了中间D皮层的表皮损伤,例如强烈的皱纹,孔洞和结节状结构。总的来说,arctigenin的结构优化分析表明4a和4b可用于预防和控制Dactylogyrus感染,并被认为是开发商业药物的有前途的先导化合物。
