  Preparation and Structure-Activity Relationships of Novel Asterriquinone Derivatives.

  摘要：

  Asterriquinone (ARQ, 1a) 是青霉菌 (Aspergillus terreus IFO 6123) 的一种抗肿瘤代谢产物。为了深入了解 ARQ 的结构-活性关系，准备了一系列化学修饰的衍生物 (1-6)，ARQ 同源物 (b-e) 和 2, 5-二羟基-p-苯醌同源物 (f-h)，并研究了其对小鼠白血病 P388 细胞的细胞毒性活性。结果表明：1）在 p-苯醌部分至少需要一个羟基或乙酰氧基才能表现出细胞毒性；2）在 p-苯醌部分，单个甲氧基和/或一个乙酰氧基的取代比两个羟基取代时表现出更强的细胞毒性 (1)；3）吲哚环对 ARQ 同源物的细胞毒性具有重要作用；4）吲哚环中的 1, 1-二甲基-2-丙烯基对 ARQ 的细胞毒性活性并不重要。

• Phytotoxic Activity of Quinones and Resorcinolic Lipid Derivatives
  作者：Cassia S. Mizuno、Agnes M. Rimando、Stephen O. Duke

  DOI：10.1021/jf100108c

  日期：2010.4.14

  basis of the reported phytotoxic activity of sorgoleone and resorcinolic lipids identified from the root extracts of Sorghum bicolor, 8 resorcinolic lipid derivatives and 10 quinones with various side chain sizes were synthesized. The phytotoxicity of the compounds was tested against a monocot and a dicot species. The quinones were phytotoxic, whereas the resorcinolic lipids were not. Of the quinones,

  根据报道的从高粱双色根提取物中鉴定出的高粱油酮和间苯二酚脂质的植物毒性活性，合成了8种间苯二酚脂质衍生物和10种具有不同侧链大小的醌。测试了化合物对单子叶植物和双子叶植物的植物毒性。醌具有植物毒性，而间苯二酚脂质则没有。在醌中，具有5个碳侧链的2-羟基-5-甲氧基-3-戊基环己-2,5-二烯-1,4-二酮显示出与天然化合物高粱油酮相似的植物毒活性。

  There is disclosed a method and composition for controlling rust disease in plants. Metabolites produced by Aphanocladium album mycoparasites are recovered and applied in an effective amount to plants at risk for acquiring rust disease More specifically, the application of the metabolite converts infective urediniospores that cause rust disease into non-infective teliospores. In a more specific aspect, the metabolite is reacted with another substance or under a specific reaction to result in a different compound which is also effective against rust disease.

  本发明揭示了一种用于控制植物锈病的方法和组合物。通过Aphanocladium album真菌寄生体产生的代谢物被提取并以有效量施用于有患锈病风险的植物上。更具体地，代谢物的施用将导致引起锈病的传染性锈子孢子转变为非传染性的子囊孢子。在更具体的方面，这种代谢物与另一种物质或在特定反应条件下反应，形成对锈病也有效的不同化合物。
