available algicides in the market are nonselective and have potential side effects on nontarget species. In the present work, two series of compounds (4 and 6) comprising 16 novel 1,2,3-triazole aminopyrimidines were rationally designed and synthesized as control agent for cyanobacteria. Our design focus was the inhibiting cyanobacteria by inhibition against pyruvate dehydrogenase complex E1 (PDHc-E1)
蓝藻有害藻华是全球关注的问题,但是市场上目前所有可用的杀藻剂都是非选择性的,并且对非目标物种具有潜在的副作用。在目前的工作中,合理设计并合成了包含16个新的1,2,3-三唑氨基嘧啶的两类化合物(4和6)作为蓝细菌的防治剂。我们的设计重点是通过抑制丙酮酸脱氢酶复合物E1(PDHc-E1)来抑制蓝细菌。化合物4和6显示出对强效抑制大肠杆菌PDHC-E1(IC 50 = 4.13-23.76μM)和对也强杀藻活动集胞藻。PCC 6803(EC50 = 1.7–8.1μM)和微囊藻。FACHB905(EC 50 = 2.1–11.8μM)。特别是6d对4种藻类的杀藻活性不仅高于prometricn。它们也与硫酸铜相当或更高。类似物4c,4d,6d和6e显示出强效的杀藻活性和对大肠杆菌PDHc-E1的抑制作用,但对猪PDHc-E1的抑制作用却可以忽略不计。如分子对接,定点诱变,酶促测定和抑制动力学分
