Triterpene Biosynthesis in the Latex of Euphorbia lathyris: Effect of Calmodulin Antagonists and Chlorinated Phenoxy Compounds.
Recognized calmodulin antagonists and chlorinated phenoxyalkylamines were tested as inhibitors of mevalonate incorporation into triterpenols and their fatty acid esters in a centrifuged pellet from the latex of Euphorbia lathyris. The calmodulin antagonists, chlorpromazine (II), fluphenzine, and trifluoperazine were good inhibitors; I(50) values for II and trifluoperazine were 150 and 55 microm...
متن کاملExposure to Euphorbia lathyris latex resulting in alkaline chemical injury: a case report
INTRODUCTION We report the case of a patient with extreme pain following accidental exposure to the latex of Euphorbia lathyris. CASE PRESENTATION A 76-year-old Caucasian woman attended the ophthalmology department with acute severe bilateral eye pain. This occurred immediately after having pulled a weed out of her garden with her bare hands. She recalled having subsequently rubbed her eyes. ...
متن کاملEnhancement of Terpenoid Biosynthesis from Mevalonate in a Fraction of the Latex from Euphorbia lathyris.
A latex pellet fraction from Euphorbia lathyris incorporates mevalonate into triterpenols and their fatty acid esters. Conditions for improved incorporation were determined. CaCl(2) or CaCl(2) plus MnCl(2) stimulated biosynthesis, and the metal ion chelator, ethylenebis(oxyethylenenitrilo)tetraacetic acid (EGTA) enhanced stimulation. Ethylenediaminetetraacetic acid was almost as effective as EG...
متن کاملPhytochemicals of Euphorbia lathyris L. and Their Antioxidant Activities.
The objectives of this study were to characterize the antioxidant capacities and phytochemicals such as phenolics and flavonoids in four parts of Euphorbia lathyris L. HPLC was employed to detect the type and content of phenolic acids and flavonoids in the root, stem, seed, and testa of the plant. The total phenolic content (TPC) and total flavonoid content (TFC) were different among various pa...
متن کاملEuphorbia factor L8: a diterpenoid from the seeds of Euphorbia lathyris
THE TITLE COMPOUND [SYSTEMATIC NAME: (2S*,3S*,4R*,5R*,9S*,11S*,15R*)-5,15-diacet-oxy-3-nicotino-yloxy-14-oxolathyra-6(17),12(E)-diene], C(30)H(37)NO(7), was isolated from the seeds of Euphorbia lathyris. The tricyclic diterpenoid molecule contains an 11-membered ring, a five-membered ring exhibiting an envelope conformation and a three-membered ring. The 11-membered ring is cis-fused with the t...
