crystallography. The anthelmintic activity of the newly designed analogues was evaluated in vitro against the economically important parasites Haemonchus contortus and Trichostrongylus colubriformis. Moderate nematocidal activity was observed for nine of the 27 compounds. Three compounds were confirmed as potentiators of a known monepantel target, the ACR‐23 ion channel. Production of reactive oxygen
由于在世界范围内遇到的耐药性问题,对动物寄生虫的新药的发现需求很高。在此,合成以及最近推出的杀线虫药monepantel(Zolvix 27个有机和有机金属衍生物的表征®)中有所描述。分离出化合物为外消旋体,并通过1 H,13 C和19 F NMR光谱,质谱和IR光谱进行表征,并通过微量分析验证其纯度。X射线晶体学证实了9种化合物的分子结构。新设计的类似物的驱虫活性在体外针对经济上重要的寄生虫Haemonchus contortus进行了评估。和Trichostrongylus colubriformis。对27种化合物中的9种观察到中等的杀线虫活性。三种化合物被确认为已知的monepantel靶标ACR-23离子通道的增强剂。活性氧物质的产生可赋予有机金属类似物第二活性。两种化合物,即,有机前体(3)和一个cymantrene类似物(9),显示出对抗的微丝蚴的活动犬恶丝虫在每毫升范围低微克。
