Iridoid Sex Pheromone Biosynthesis in Aphids Mimics Iridoid‐Producing Plants [PDF]

Chemistry – A European Journal, 2021
AbstractBiosynthesis of (1R,4aS,7S,7aR)‐nepetalactol (1) and (4aS,7S,7aR)‐nepetalactone (2) in plants involves iridoid synthase (ISY), an atypical reductive cyclase that catalyses the reduction of 8‐oxogeranial into the reactive enol of (S)‐8‐oxocitronellal, and cyclization of this enol intermediate, either non‐enzymatically or by a nepetalactol ...

Biosynthesis of iridoid sex pheromones in aphids [PDF]

bioRxiv, 2022
Iridoid monoterpenes, widely distributed in plants and insects, have many ecological functions. While the biosynthesis of iridoids has been extensively studied in plants, little is known about how insects synthesize these natural products.

Identification of iridoid synthases from Nepeta species: Iridoid cyclization does not determine nepetalactone stereochemistry

bioRxiv, 2017
Iridoid synthase from Nepeta cateria (catnip) and Nepeta mussinii, have been cloned and characterized. Abstract Nepetalactones are iridoid monoterpenes with a broad range of biological activities produced by plants in the Nepeta genus.
