thiophene derivative, in silico molecular modeling studies were carried out with the glutamate-activated chloride channel (GluCl), a well-known molecular target of anthelmintic compounds. Based on the affinity score (GlideScore = -5.7 kcal.mol−1) and the proposed binding mode, Thio1 could be classified as a potential GluCl ligand, justifying the promising results observed in the anthelmintic assays.
以前在Tagetes patula中鉴定出的噻吩化合物的合成表明,4-(5'-(羟甲基)-[2,2'-联噻吩] -5-基)but-3-yn-1-ol)或简单地Thio1具有明显的体外抗驱虫性驱虫作用,在卵孵化和幼体发育试验中显示出100%的功效,其中EC 50 = 0.1731 mg.mL -1和EC 50 = 0.3243 mg.mL -1, 分别。因此,选择了该化合物来制备纳米结构的制剂,该制剂将口服给予SantaInês绵羊。通常,通过粪便卵数减少试验(FECRT),可以观察到该产品使宿主消化道中的寄生虫负荷保持稳定,每克粪便中的卵数(EPG)平均值<3,000( EPG平均值 = 2167.1,功效= 36.45%),从而保护动物免受大规模线虫侵扰引起的健康风险。为了更好地理解该噻吩衍生物的作用方式,使用谷氨酸激活的氯离子通道(GluCl)(一种驱虫化合物的著名分子靶标)进行了
