this article, 23 myricetin derivatives containing thiazolebisamides active groups have been designed and synthesized. Their activities were evaluated by performing in vitro antibacterial and in vivo antiviral assays, microscale thermophoresis (MST) and molecular docking assays. The results of in vivo antiviral assays showed that compounds A4 and A23 exhibited good antiviral activity with EC50 values
由病毒、细菌、真菌等多种病原体引起的植物病害对全球粮食生产和食品安全构成巨大威胁。因此,寻找绿色、高效、无污染的农药已成为一项重要任务。本文设计并合成了23种含有噻唑双酰胺类活性基团的杨梅素衍生物。通过进行体外抗菌和体内抗病毒测定、微尺度热泳(MST)和分子对接测定来评估它们的活性。体内抗病毒试验结果表明,化合物A4和A23表现出良好的抗病毒活性,治疗活性的EC 50值分别为79.0和54.1 μg/mL,保护活性的EC 50 值分别为103.3和91.2 μg/mL。通过微量热泳(MST)测定,化合物A4和A23对TMV-CP的解离常数(Kd)值分别为0.021和0.018μM,远小于商品化药物宁南霉素(NNM)的2.84。微米。化合物A4 、 A23与TMV-CP的相互作用在分子水平上得到进一步验证。此外,该系列化合物的体外抗真菌试验表明,它们对多种真菌,尤其是辣椒疫霉表现出一定的抑制活性。其中,
