Abstract Objective: Different 5-substituted benzimidazole-2-yl ureaderivatives were designed and synthesized to evaluate their anthelmintic activity. Methods: The derivatives were prepared according to the previously reported method with little modification. The synthesized compounds were purified by crystallization and characterized by IR, 1H NMR, 13C NMR, and MS data. The anthelmintic activities
抽象的 目的:设计合成不同的5-取代苯并咪唑-2-基脲衍生物并评价其驱虫活性。方法:根据先前报道的方法制备衍生物,稍作修改。合成的化合物通过结晶纯化,并通过 IR、 1 H NMR、 13 C NMR 和 MS 数据进行表征。在进行体外评估之前,通过使用 PASS(物质活性谱预测)来确定所设计的化合物的驱虫活性。结果与讨论:化合物的合成收率良好,产率在 70-80% 之间。 PASS(物质活性谱预测)分析预测了化合物可能的驱虫活性(0.5 > p a < 0.7)。三种合成化合物(IId)、(IIId)和(IVd)在平均麻痹时间和平均死亡时间方面显示出与阿苯达唑相当的驱虫活性。与标准药物阿苯达唑 (–43.87) 相比,化合物 (IId)、(IIId) 和 (IVd) 分别表现出优异的对接分数 –43.24、–35.14 和 –34.17 kcal/mol。结论:所有三种活性化合物均通过

This work outlines the synthesis and solid-state structures of a series of ureidoimidazole derivatives. The ureidoimidazoles all adopt a common tautomeric configuration and possess remarkably consistent features of supramolecular organisation that are affected by both steric factors and proximal hydrogen-bonding functionality.
