4R-cembranoid protects against diisopropylfluorophosphate-mediated neurodegeneration [PDF]

open access: yesNeuroToxicology, 2014
Many organophosphorous esters synthesized for applications in industry, agriculture, or warfare irreversibly inhibit acetylcholinesterase, and acute poisoning with these compounds causes life-threatening cholinergic overstimulation. Following classical emergency treatment with atropine, an oxime, and a benzodiazepine, surviving victims often suffer ...

Manipulation of CBTS1 Expression Alters Tobacco Resistance to Spodoptera frugiperda and Phytophthora nicotianae

open access: yesAgronomy, 2023
Cembranoids produced by tobacco glandular trichomes have bioactivities in resistance to insect pests and pathogens. Cembratrien-ol synthase (CBTS) plays a key role in the biosynthesis of cembranoids and directly determines the cembranoid content in ...

New Cembranoids from Burley Tobacco

open access: yesZeitschrift für Naturforschung C, 1981
Abstract The liquid CO2-extract of aged burley tobacco was investigated for its content of diterpenoids, which are considered as important precursors of flavour constituents. Among several cembranoids, already known from various tobacco types, 4,8-dimethyl-8-hydroxy-11-(1-methyl-ethyl)-14-oxo-pentadeca-5,9-diene-4-olide, a new natural ...

On‐Line Analysis of Cigarette Smoke Based on Microwave Plasma Torch Mass Spectrometry

open access: yesChemistryOpen, Volume 13, Issue 9, September 2024.
Cigarette smoke contains a large number of flavor components and harmful substances, so it is crucial to establish an effective method for smoke detection and analysis. This article provides a method for on‐line analysis of smoke with MPT‐MS (Microwave plasma torch mass spectrometry), and achieved detection of 22 flavor compounds and 2 polycyclic ...
