In recent years, naturally occurring tetrahydro-β-carboline (THC) alkaloids and their derivatives have been of biological interest. However, few studies and developments have reported the use of such structures in managing plant bacterial diseases. Herein, an array of novel THC derivatives containing an attractive 1,3-diaminopropan-2-ol pattern were prepared to evaluate the antiphytopathogen activity
近年来,天然存在的四氢-β-咔啉(THC)生物碱及其衍生物已引起生物学兴趣。但是,很少有研究和开发报道这种结构用于控制植物细菌性疾病。在本文中,含有一个有吸引力的1,3-二氨基丙-2-醇图案新颖THC衍生物的阵列,制备评价antiphytopathogen活性在体外和体内和探索创新抗菌框架。值得注意的是,目标化合物对三种反叛性植物病原体,即丁香假单胞菌pv表现出出色的活性。猕猴桃(Psa),Xanthomonas axonopodis pv。柠檬和黄单胞菌(Xanthomonas oryzae)。稻米,相关的最佳EC50个值分别为2.39(II 9),2.06(I 23)和1.69(II 9)μg/ mL。这些效果优于母体结构1,2,3,4-THC和阳性对照。体内试验表明,II 9分别在200μg/ mL时对水稻白叶枯病和奇异果细菌溃疡病和I 23表现出极好的控制效率,分别为51.89和65
