A series of novel chiral thioureas 3a-n bearing leucine and phosphonate moieties were synthesized in excellent yields. The structures of the compounds were completely characterized by elemental analysis, IR, 1H-, 13C-, 31P- and 19F-NMR spectral data. A half-leaf method was used to determine the in vivo protective and curative efficacies of the title products against tobacco mosaic virus (TMV). The compounds 3l and 3n displayed good in vivo protection and curative effects against TMV with inhibitory rates of 60.1, 62.8% (protection) and 56.7, 53.6% (curative) at 0.5 mg/mL, respectively. To the best of our knowledge, this is the first report on the antiviral activity of chiral thioureas containing leucine and phosphonate moieties.
一系列含有亮氨酸和膦酸基团的新型手性硫脲化合物3a-n被合成,产率极佳。通过元素分析、红外、1H-、13C-、31P-和19F-NMR光谱数据,这些化合物的结构得到了完全表征。采用半叶法测定了标题产品对烟草花叶病毒(TMV)的体内保护和治疗功效。化合物3l和3n在0.5 mg/mL浓度下显示出良好的体内保护和治疗效果,抑制率分别为60.1%、62.8%(保护)和56.7%、53.6%(治疗)。据我们所知,这是首次报道含有亮氨酸和膦酸基团的手性硫脲的抗病毒活性。
