为了发现具有杀菌活性的新型先导化合物, 基于几丁质合成酶催化作用机制, 通过活性亚结构拼接方法, 保留多氧霉素和尼克霉素中的活性尿苷部分, 将具有良好杀菌活性的硫脲基团引入, 设计合成了一系列含硫脲结构的核苷类化合物. 以尿苷为原料, 经5 步反应制得目标物, 其结构经IR, 1H NMR 及元素分析确证. 初步生测结果表明, 部分化合物对芦笋茎枯病(Phomopsisasparagi bubak)表现出明显的抑制活性, 其中6m 的抑制率在50 μg/mL 浓度下为97.2%,与相同浓度的多氧霉素B 活性(100%)接近.

To find new fungicidal lead compounds, based on the catalytic mechanism of chitin synthase, a series of novel nucleoside compounds containing thiourea were designed via the method of linking active sub-structures, in which the thiourea with high fungicidal activity was combined to the uridine part of polyoxins and nikkomycins. The target compounds were synthesized from uridine in 5 steps. Their structures were confirmed by IR, 1H NMR spectra and elemental analysis. The preliminary bioassay results indicated that some compounds showed obvious inhibition effects against Phomopsisasparagi bubak, especially, and the fungicidal activity of 6m (97.2%) at 50 μg/mL is similar to that (100%) of polyoxin B.
