Investigation of the accumulation of 2,4-dichlorophenoxyacetic acid (2,4-D) in rat kidneys

, 2005
The accumulation of 2,4-dichlorophenoxyacetic acid (2,4-D) and its metabolite 2,4-dichlorophenol (2,4-DCP) in the kidneys of rats was investigated. Male and female Sprague-Dawley rats were given 2,4-D in drinking water and food for 30 days.

Carbofuran, Malathion and 2,4-D Degradation by Bacterial Activity

, 2018
The indiscriminate use of pesticides in agricultural practice in recent years has generated various environmental problems, since these compounds tend to bioaccumulate through trophic chains presenting considerable levels of toxicity and conditioning ...

Ein chirales, sattelförmiges Nanographen mit zwei Heptagon‐integrierten [4]Helicenen

Angewandte Chemie, EarlyView.
Wir präsentieren eine neuartige Synthesestrategie für ein chirales, sattelförmiges Nanographen (cSNG) über eine zweistufige Oxidation eines prochiralen Anthracen‐Vorläufers. Die Scholl‐Oxidation liefert zunächst ein Schlüsselzwischenprodukt mit sp3‐defekten Heptagonen, die anschließende oxidative Dehydrierung ergibt das vollständig konjugierte cSNG ...

Cobalt‐Catalyzed Radical Ligand Transfer (RLT) Enables Remote‐Markovnikov Hydroamination of Alkenes

Angewandte Chemie, EarlyView.
A cobalt‐catalyzed remote‐Markovnikov 1,3‐hydroamination of allyl carboxylates proceeds through MHAT, 1,2‐radical acyloxy migration (1,2‐RAM), and radical ligand transfer (RLT) from a Co‐N intermediate, providing protected amino alcohols. ABSTRACT Amino alcohols are prevalent in pharmaceuticals, agrochemicals, and functional materials, yet ...

Effects of olive oil and its fractions on oxidative stress and the liver's fatty acid composition in 2,4-Dichlorophenoxyacetic acid-treated rats

Nutrition & Metabolism, 2010
Background Olive oil's beneficial effects are not only related to its high content of oleic acid, but also to the antioxidant potential of its polyphenols.

2,4-D impact on bacterial communities, and the activity and genetic potential of 2,4-D degrading communities in soil

, 2006
The key role of telluric microorganisms in pesticide degradation is well recognized but the possible relationships between the biodiversity of soil microbial communities and their functions still remain poorly documented.

Funktionalisierung von Peptiden auf der festen Phase im späten Synthesestadium

Angewandte Chemie, EarlyView.
Peptidmodifikationen sind für die Kontrolle der Eigenschaften von Peptidwirkstoffen von entscheidender Bedeutung. Daher sind Strategien, die einen effizienten und schnellen Einbau nicht‐kanonischer Modifikationen in Peptide in Parallelformaten ermöglichen, sehr gefragt.

Comparative metabolism of 2,4-dichlorophenoxyacetic acid (2,4-D) in rat and dog

, 2013
1. There is a significant species difference in the toxicity of 2,4-dichlorophenoxyacetic acid (2,4-D). The oral no overall adverse effect level (NOAEL) for chronic toxicity of 2,4-D in rat is 5 mg kg(-1) day(-1) and in dog is 1 mg kg(-1) day(-1).

Three Component Thio‐ and Carboboration of Alkynes: A Modular Route to Functionalised Bicyclic Boronates

Angewandte Chemie, EarlyView.
Three‐component thio‐ and carbo‐boration reactions to form functionalised benzoxaborinines and benzazaborinines are reported. The nucleophile scope includes thioethers, thiols, and (hetero)arenes. Mechanistic studies revealed a disparity between thioboration using thioethers and using thiols.
