panel of ascarosides and tested them for dauer-inducing activity. This panel includes a number of natural ascarosides that were detected in crude pheromone extract, but as yet have no assigned function, as well as many unnatural ascaroside derivatives. Most of these ascarosides, some of which have significant structural similarity to the natural dauer pheromone components, have very little dauer-inducing
线虫秀丽隐杆线虫分泌蛔苷,3,6-双脱氧糖蛔糖的结构多样的衍生物,并将它们用于化学通讯。在高人口密度下,特定的蛔苷(统称为 dauer 信息素)会触发进入抗应激的 dauer 幼虫阶段。为了研究蛔苷的构效关系,我们合成了一组蛔苷并测试它们的诱导活性。该面板包括许多在粗信息素提取物中检测到但尚未指定功能的天然蛔苷,以及许多非天然蛔苷衍生物。大多数这些蛔苷(其中一些与天然 dauer 信息素成分具有显着的结构相似性)几乎没有诱导 dauer 的活性。
