Organic peroxides' gas-particle partitioning and rapid heterogeneous decomposition on secondary organic aerosol [PDF]

open access: yesAtmospheric Chemistry and Physics, 2016
Organic peroxides, important species in the atmosphere, promote secondary organic aerosol (SOA) aging, affect HOx radicals cycling, and cause adverse health effects. However, the formation, gas-particle partitioning, and evolution of organic peroxides

Peroxides with Anthelmintic, Antiprotozoal, Fungicidal and Antiviral Bioactivity: Properties, Synthesis and Reactions

open access: yesMolecules, 2017
The biological activity of organic peroxides is usually associated with the antimalarial properties of artemisinin and its derivatives. However, the analysis of published data indicates that organic peroxides exhibit a variety of biological activity ...

Ginseng Prong Added to Broiler Diets Reduces Lipid Peroxidation in Refrigerated and Frozen Stored Poultry Meats

open access: yesMolecules, 2021
Fatty acid content and lipid oxidation products were compared in chicken breast and leg meats derived from birds fed on animal-fat- and vegetable-oil-based diets, supplemented with ginseng prong powder. The first experiment examined polyunsaturated fatty

Oxidation of Drugs during Drug Product Development: Problems and Solutions

open access: yesPharmaceutics, 2022
Oxidation is the second most common degradation pathway for pharmaceuticals, after hydrolysis. However, in contrast to hydrolysis, oxidation is mechanistically more complex and produces a wider range of degradation products; oxidation is thus harder to ...

Tetraoxanes as inhibitors of apicomplexan parasites Plasmodium falciparum and Toxoplasma gondii and anti-cancer molecules [PDF]

open access: yesJournal of the Serbian Chemical Society, 2015
New cyclohexylidene 1,2,4,5-tetraoxanes with polar guanidine and urea based groups were synthesized and evaluated for antimalarial activity against chloroquine resistant and susceptible Plasmodium falciparum strains.

Synthetic Approaches to Mono- and Bicyclic Perortho-Esters with a Central 1,2,4-Trioxane Ring as the Privileged Lead Structure in Antimalarial and Antitumor-Active Peroxides and Clarification of the Peroxide Relevance

open access: yesMolecules, 2017
The synthesis of 4-styryl-substituted 2,3,8-trioxabicyclo[3.3.1]nonanes, peroxides with the core structure of the bioactive 1,2,4-trioxane ring, was conducted by a multistep route starting from the aryl methyl ketones 1a–1c.

Rearrangements of organic peroxides and related processes

open access: yesBeilstein Journal of Organic Chemistry, 2016
This review is the first to collate and summarize main data on named and unnamed rearrangement reactions of peroxides. It should be noted, that in the chemistry of peroxides two types of processes are considered under the term rearrangements.

The decomposition of alkyl peroxides: dipropyl peroxide, ethyl hydrogen peroxide and propyl hydrogen peroxide [PDF]

open access: yesProceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1939
In a previous paper (Harris and Egerton 1938) the results of an investigation of the decomposition of diethyl peroxide have been published. The present communication deals with the related compounds ( a ) dipropyl peroxide, which closely resembles the diethyl compound as it decomposes unimolecularly, ( b
