Journal ArticleDOI
Insects pharmacophagously utilizing defensive plant chemicals (Pyrrolizidine alkaloids)
TL;DR: Insects of several orders gather alkaloids independent of feeding behaviour and in various species the plant chemicals are used as precursors for the biosynthesis of male pheromones; in Creatonotos they even regulate specifically the development of the androconial organs.
Journal ArticleDOI
Lepidoptera and pyrrolizidine alkaloids Exemplification of complexity in chemical ecology
TL;DR: This article discusses selected behavioral, chemical, physiological, and phylogenetic aspects of insect-PA relationships, and raises questions about the complex interactions of the variety of PA-related adaptations as they occur among a diverse array of species.
Journal ArticleDOI
Pyrrolizidine alkaloids in food: a spectrum of potential health consequences
TL;DR: Growing recognition of hazardous levels of dehydroPAs in a range of common foods suggests that physicians and clinicians need to be alert to the possibility that these contaminants may, in some cases, be a possible cause of chronic diseases such as cirrhosis, pulmonary hypertension and cancer in humans.
Journal ArticleDOI
The two Faces of Pyrrolizidine Alkaloids: the Role of the Tertiary Amine and its N‐Oxide in Chemical Defense of Insects with Acquired Plant Alkaloids
Rainer Lindigkeit,Andreas Biller,Markus Buch,Hans-Martin Schiebel,Michael Boppré,Thomas Hartmann +5 more
TL;DR: The novel enzyme was named senecionine N-oxygenase (SNO), which isolated from the haemolymph of the sequestering arctiid Tyria jacobaeae and purified to electrophoretic homogeneity, and showed the same general substrate specificity but differ in their affinities towards the main structural types of pyrrolizidine alkaloids.
Journal ArticleDOI
Pyrrolizidine alkaloids of Echium vulgare honey found in pure pollen
TL;DR: Pyrrolizidine alkaloids and/or their N-oxides were isolated from the aqueous acid extracts of pollen by use of strong cation-exchange, solid-phase extraction and identified by liquid chromatographic/mass spectrometric (LCMS) analysis.
