Heterogeneity of iridoid biosynthesis in catmints: Molecular background in a phylogenetic context. [PDF]

J Integr Plant Biol
Evolutionary gains and losses of key biosynthetic genes likely resulting from multiple independent evolutionary events explain why certain Nepeta (catnip) species produce both the active, cat‐attracting nepetalactones and sugar‐bound iridoids, while others make only the sugar‐bound forms, and some have lost iridoid production entirely.

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 ...

Nine Unique Iridoids and Iridoid Glycosides From Patrinia scabiosaefolia [PDF]

Frontiers in Chemistry, 2021
Patrinia scabiosaefolia is a medical and edible Chinese herb with high nutritional and medicinal value. The continuing study of its chemical constituents led to the discovery of nine unique iridoids and iridoid glycosides, including three new iridoids (1-3) and six previously unknown irioid glycosides (5-10), and one known compound (4).
