self-assembly process of Tobacco Mosaic Virus (TMV). This research employed TMV-CP as a primary target for virtual screening, from which a library of 43,417 compounds was sourced and was chosen as the lead compound. Consequently, a series of α-amide phosphate derivatives were designed and synthesized, exhibiting remarkable anti-TMV efficacy. The synthesized compounds were found to be beneficial in treating
烟草花叶病毒外壳蛋白(TMV-CP)对于病毒的复制、运动和传播以及宿主植物的免疫系统识别它是不可或缺的。它构成病毒颗粒的最外层,是病毒结构的重要组成部分。 TMV-CP 对于启动和延长病毒组装至关重要,在烟草花叶病毒 (TMV) 的自组装过程中发挥着至关重要的作用。该研究采用 TMV-CP 作为虚拟筛选的主要目标,从中获取了包含 43,417 种化合物的库,并被选为先导化合物。因此,设计并合成了一系列α-酰胺磷酸衍生物,表现出显着的抗TMV功效。发现合成的化合物有利于治疗 TMV,其疗效略优于宁南霉素 (NNM) (EC = 304.54 µg/mL),EC 为 291.9 µg/mL。此外,其灭活活性 (EC = 63.2 µg/mL) 与 NNM (EC = 67.5 µg/mL) 相当,且具有与 NNM (EC = 219.7 µg/mL) 类似的保护活性 (EC = 228.9 µg/mL)。微量热分析表明
