quality. Algaecide is an effective way to control HCBs effectively. In this study, we applied an active substructure splicing strategy for rapid discovery of algicides. Through this strategy, we first optimized the structure of the lead compound S5, designed and synthesized three series of thioacetamide derivatives (series A, B, C), and then evaluated their algicidal activities. Finally, compound A3 with
全世界的湖泊和水库都面临着日益严重的有害蓝藻水华 (HCB) 问题,这对生态系统健康和水质产生了重大影响。除藻剂是有效控制六氯苯的有效方法。在这项研究中,我们应用了主动子结构剪接策略来快速发现灭藻剂。通过该策略,我们首先优化了先导化合物S5的结构,设计并合成了三个系列的硫代乙酰胺衍生物( A系列、 B系列、 C系列),然后评估了它们的杀藻活性。最终发现了性能优异的化合物A3 ,加速了新型杀藻剂的发现和开发进程。生物活性测定数据表明A3对铜绿假单胞菌有显着的抑制作用。 FACHB905 (EC 50 = 0.46 μM) 和集胞藻属sp。 PCC6803 (EC 50 = 0.95 μM),优于商用杀藻剂扑草净 ( M. aeruginosa . FACHB905, EC 50 = 6.52 μM;集胞藻 PCC6803, EC 50 = 4.64 μM),也优于先导化合物S5 (铜绿分枝杆菌FACHB905,EC
