在秀丽隐杆线虫中,Dauer信息素是进入抗逆性、非衰老的Dauer幼虫阶段的主要信号,Dauer信息素由3,6-二脱氧糖子囊糖的一些衍生物组成。在这里,使用活性引导的分馏和基于核磁共振的结构阐明,鉴定了一种结构新颖的吲哚-3-羧基修饰的蛔虫苷,它在低纳摩尔浓度下促进Dauer的形成,但在较高浓度时抑制Dauer的形成。
In Caenorhabditis elegans, the dauer pheromone, which consists of a number of derivatives of the 3,6-dideoxysugar ascarylose, is the primary cue for entry into the stress-resistant, ‘non-aging’ dauer larval stage. Here, using activity-guided fractionation and NMR-based structure elucidation, a structurally novel, indole-3-carboxyl-modified ascaroside is identified that promotes dauer formation at low nanomolar concentrations, but inhibits dauer formation at higher concentrations.
