To elucidate the deuterium isotope effect (DIE) in pheromonal activity and to investigate the biosynthetic pathway of 4,8-dimethyldecanal (4,8-DMD; 1), the aggregation pheromone of the red flour beetle (Tribolium castaneum), deuterated analogues of 4,8-DMDs (2, 3, 4, and 5), were synthesized and their pheromonal activities were tested using a two-hole pitfall olfactometer. Although no apparent DIE was observed in their pheromonal activities, 4,8-DMD-1-d1 (2) was less attractive than other analogues, which suggested that the bond distance between the formyl group of 1 and its receptor was critical in pheromone recognition by T. castaneum.

为了阐明氘同位素效应(DIE)在信息素活性中的作用,并探讨4,8-二甲基癸醛(4,8-DMD;1)的生物合成途径,合成了4,8-DMD的氘代类似物(2、3、4和5),并使用双孔坑式嗅觉仪测试了它们的信息素活性。尽管在它们的信息素活性中未观察到明显的DIE,4,8-DMD-1-d1(2)的吸引力低于其他类似物,这表明1的羰基与其受体之间的键长在T. castaneum对信息素的识别中是关键因素。版权 © 2004 John Wiley & Sons, Ltd.
