Phytochemical profiling of iranian plants, and ECD calculation as tool for establishing the absolute configuration of new natural products
Biosynthesis of secondary metabolites occurs by concerted multistep reactions in a biological (chiral) environment. Therefore, many natural products (NPs) are chiral molecules having one or several…
Hairy root induction and Farnesiferol B production of endemic medicinal plant Ferula pseudalliacea
- Medicine, Biology3 Biotech
Hairy roots lines from the strain ATCC 15834 produced more hairy root numbers and fresh and dried biomass compared to that of the strain 1724 and transgenic hairy root lines were confirmed by PCR amplification of rolB gene.
Three-Component Reactions of 7-Hydroxy Coumarin Derivatives, Acetylenic Esters and Aromatic Aldehydes in the Presence of NEt3
Three-component reactions of 7-hydroxy-4-methyl coumarin or 7-hydroxy-4-(trifluoromethyl) coumarin, dialkyl acetylenedicarboxylates and aromatic aldehydes in the presence of NEt3 lead to dialkyl…
GENDER DIMORPHISM AND ALTITUDINAL VARIATION OF SECONDARY COMPOUNDS IN LEAVES OF THE GYNODIOECIOUS SHRUB Daphne laureola
- Environmental ScienceJournal of Chemical Ecology
The concentration of coumarins in leaves of female and hermaphrodite individuals of the gynodioecious shrub Daphne laureola, along an elevational gradient in southern Spain, is analyzed, finding the first evidence of gender differences in chemical defenses of a gynoecious species in the field.
Synergism between myristicin and xanthotoxin, a naturally cooccurring plant toxicant
- BiologyJournal of Chemical Ecology
The fact that there was no increase in the deterrency of xanthotoxin in the presence of myristicin suggests that the mechanism of synergism is not behaviorial but rather is biochemical, via MDP competitive inhibition of microsomal mixed function oxidases.
Dietary and Developmental Influences on Induced Detoxification in an Oligophage
- Biology, Environmental ScienceJournal of Chemical Ecology
The profile of detoxification within individuals of this species appears to be genetically fixed, although there is considerable variation in profiles among individuals.
Toxicity of linear furanocoumarins toSpodoptera exigua: Evidence for antagonistic interactions
- BiologyJournal of Chemical Ecology
The linear furanocoumarins psoralen, bergapten, and xanthotoxin were tested for toxicity to the beet armyworm Spodoptera exigua under short ultraviolet (UVB) radiation and the enigma the findings represent for plant-insect relationships are discussed.
Cumarinas presentes en especies del género "Casimiroa"
Los extractos organicos de hojas y semillas de Casimiroa pubescens, C. edulis y C. calderoniae se analizaron mediante cromatografia liquida de alta resolucion; los resultados mostraron la presencia…
Studies on the substrate specificity of human intestinal UDP- lucuronosyltransferases 1A8 and 1A10.
- Biology, ChemistryDrug metabolism and disposition: the biological fate of chemicals
Two UDP-glucuronosyltransferase (UGT) isoforms of human intestinal mucosa, which are absent in liver, have been identified by reverse transcriptase-polymerase chain reaction and suggest that human intestinal UGTs may play an important role in the detoxification of xenobiotic compounds and, in some cases, limit the bioavailability of therapeutic agents.
