to the production of rice all over the world. To develop an efficient antibacterial agent with a novel target, a series of novel 2-oxo-N-phenylacetamide derivatives containing a dissulfone moiety were synthesized, and their antibacterial activities were evaluated. Among them, compound D14 exhibited the best antibacterial activities, especially against Xoo and Xoc with EC50 values of 0.63 and 0.79 mg/L
水稻白叶枯病和水稻白条病是两种严重的水稻病害,对世界范围内的水稻生产造成了极大的危害。为了开发具有新靶点的高效抗菌剂,合成了一系列含有二砜部分的新型2-氧代-N-苯乙酰胺衍生物,并对其抗菌活性进行了评价。其中,化合物D 14表现出最好的抗菌活性,尤其是对Xoo和Xoc的抑菌活性, EC 50值分别为0.63和0.79 mg/L,明显优于商业对照的双甲基噻唑(BT )。)(分别为 76.59 和 83.35 mg/L)和噻二唑铜 ( TC )(分别为 91.72 和 114.00 mg/L)。同时,化合物D 14可以与 Pxo99 A的 CRP 样蛋白 (Clp) 相互作用,并与Xoo -Clp表现出强结合活性, K d值为 0.52 μM,远优于BT的相应K d值。 183.94 μM ) 和TC (222.58 μM)。D 14的处理和clp基因的缺失可以显着降低clp的表达基因并减弱病原菌的毒力。这些结果表明化合物D
