Long-term dynamics of monoterpene synthase activities, monoterpene storage pools and emissions in boreal Scots pine [PDF]

open access: yesBiogeosciences, 2018
Seasonal variations in monoterpene emissions from Scots pine (Pinus sylvestris) are well documented, and emissions are often shown to follow the incident temperatures due to effects on compound volatility.

A practical way to synthesize chiral fluoro-containing polyhydro-2H-chromenes from monoterpenoids

open access: yesBeilstein Journal of Organic Chemistry, 2016
Conditions enabling the single-step preparative synthesis of chiral 4-fluoropolyhydro-2H-chromenes in good yields through a reaction between monoterpenoid alcohols with para-menthane skeleton and aldehydes were developed for the first time.

(1R,2R,6S)-2(4-(4-Isopropylbenzyl)piperazin-1-yl)-3-methyl-6-(prop-1-en-2-yl)cyclohex-3-enol

open access: yesMolbank, 2023
Parkinson’s disease (PD) is a progressive neurodegenerative disorder mainly characterized by movement dysfunction. Earlier, it was found that (1R,2R,6S)-3-methyl-6-(prop-1-en-2-yl)cyclohex-3-ene-1,2-diol (Prottremin) demonstrated antiparkinsonian ...

Anthropogenic monoterpenes aggravating ozone pollution

open access: yesNational Science Review, 2022
Abstract Monoterpenes have been known to have a critical influence on air quality and climate change through their impact on the formation of fine particles. Here we present field evidence that monoterpene oxidations largely enhanced local ozone production in a regional site in eastern China. The observed monoterpene was most likely from

Honeybees Learn Odour Mixtures via a Selection of Key Odorants [PDF]

open access: yes, 2015
BACKGROUND The honeybee has to detect, process and learn numerous complex odours from her natural environment on a daily basis. Most of these odours are floral scents, which are mixtures of dozens of different odorants.
