  Synthesis and Structure−Phytotoxicity Relationships of Acetylenic Phenols and Chromene Metabolites, and Their Analogues, from the Grapevine Pathogen Eutypa lata

  摘要：

  Eutypa lata, the fungus responsible for dying-arm disease in grapevines, produces a number of structurally related secondary metabolites, of which eutypine (1) has been implicated as the principal phytotoxin. However, analysis of an E. lata strain from California known to be pathogenic to grapevines showed that eutypine was not present, suggesting that other metabolites could be phytotoxic. Investigation of the relative phytotoxicities of individual metabolites has been limited by insufficient material and lack of a reliable bioassay. Metabolites of particular interest and their precursors were therefore synthesized, and a rapid, quantitative bioassay via topical application of individual compounds to disks of grape leaves and measurement of chlorophyll loss was developed to provide a relative measure of tissue damage. The recently reported metabolite eulatachromene (2) was found to have phytotoxicity greater than that of eutypine (1). The cyclization product, 5-formyl-2-methylvinyl[1]benzofuran (3), also showed significant activity, whereas the reduction product, eutypinol (4), was inactive, as was the quinol, siccayne (5). These results indicate that before strains of Eutypa are incriminated as pathogenic they must be analyzed for the presence or absence of specific constituents for which the phytotoxicity has been unequivocally established.

  1,4-苯醌与亲电试剂的Rh催化反应：CH碘化，溴化和苯硒化

  摘要：

  在Rh催化的条件下，典型的亲电子1,4-苯醌具有亲核反应性，因此暴露于适当的亲电子会产生CH碘化，溴化和苯硒化的产物。这为直接的卤代官能化提供了一种温和而通用的方法，并且是第一个可以实现此类化合物直接C–H苯基硒化的方法。概述了新协议的范围和局限性，并突出了代表性的衍生化。

  Rhodium-catalyzed [2 + 2 + 2] cycloadditions, sulfonyl phthalide annulations and nitroalkene reactions have been employed for the synthesis of 56 quinone-based compounds. These were evaluated against Trypanosoma cruzi, the parasite that causes Chagas disease.

  biological molecules require specific membrane transporters and channel proteins that control the traffic of these molecules into and out of the cell. This work reports that the introduction of halogen atoms into a series of fluorescent molecules remarkably enhances their cellular uptake, and that their transport can be increased to more than 95 % by introducing two iodine atoms at appropriate positions. The

  哺乳动物细胞对荧光探针和治疗剂的吸收不良是生物学应用中的一个主要问题，涉及从荧光成像到活细胞内药物传递的各种领域。尽管气态分子（例如氧气和二氧化碳），疏水性物质（例如苯）以及小的极性但不带电荷的分子（例如水和乙醇）可以通过简单的被动扩散穿过细胞质膜，但许多合成分子和生物分子都需要特定的膜转运蛋白和控制这些分子进出细胞的通道蛋白。这项工作报告说，将卤素原子引入一系列荧光分子中可以显着增强其细胞摄取，并且通过在适当位置引入两个碘原子，可以将其转运提高到95％以上。当分子中存在碘原子时，荧光团的性质在细胞摄取中并不起主要作用，因为带有萘二甲酰亚胺，香豆素，BODIPY和pyr部分的化合物显示出相似的摄取。有趣的是，引入带有两个羟乙基硫基的马来酰亚胺基荧光团使分子能够穿过质膜和核膜，碘原子的存在进一步增强了跨这两个膜的传输。总的来说，这项研究提供了增强哺乳动物细胞对有机分子吸收的一般策略。引入带有
