Formation of Benzophenanthridine Alkaloids by Suspension Cultures of Eschscholtzia californica
Eschscholtzia californica, Suspension Cultures, Benzophenanthridine Alkaloids, Phenolics, Media Effects Suspension cultures of Eschscholtzia californica accumulate the dihydro forms of the benzo phenanthridine alkaloids sanguinarine, chelirubine, macarpine and chelerythrine, all of which are known to be constituents of the Eschscholtzia plant. Under most experimental conditions dihydrochelirub...
متن کاملCharacterization of a meta-Fluorotyrosine-Tolerant Cell Culture of Eschscholtzia californica Cham.
A cell line of Eschscholtzia californica selected for meta-fluorotyrosine (MFT) tolerance was found to have 10-fold increased levels of phenylalanine and tyrosine compared to the parent line, while most other amino acids were only increased 2-fold. Tracer experiments with shikimic acid in the presence of MFT showed that the biosynthesis of the aromatic amino acids was not impaired in the tolera...
متن کاملHPLC Analysis and Biochemical Characterization of LOX from Eschscholtzia californica Cham.
BACKGROUND Plant lipoxygenases (LOXs, EC 1.13.11.12) are involved in lipid degradation, regulation of growth and development, senescence, and defence reactions. LOX represents the starting enzyme of the octadecanoid pathway. The aim of the work was to purify LOX from California poppy (Eschscholtzia californica Cham.), to determine its biochemical properties and to identify and quantify the prod...
متن کاملModulatory Effects of Eschscholzia californica Alkaloids on Recombinant GABAA Receptors
The California poppy (Eschscholzia californica Cham.) contains a variety of natural compounds including several alkaloids found exclusively in this plant. Because of the sedative, anxiolytic, and analgesic effects, this herb is currently sold in pharmacies in many countries. However, our understanding of these biological effects at the molecular level is still lacking. Alkaloids detected in E. ...
متن کاملMetabolism of alkaloids in coffee plants
Coffee beans contain two types of alkaloids, caffeine and trigonelline, as major components. This review describes the distribution and metabolism of these compounds. Caffeine is synthesised from xanthosine derived from purine nucleotides. The major biosynthetic route is xanthosine → 7-methylxanthosine → 7-methylxanthine → theobromine → caffeine. Degradation activity of caffeine in coffee plant...
