The aim of this study was to synthesize a series of ethylene glycol (EG) ethers and quinoline hybrids of the antimalarial drug artemisinin and to evaluate their antimalarial activity in vitro against Plasmodium falciparum strains. The ethers were synthesized in a one-step process by coupling ethylene glycol (EG) moieties of various chain lengths to carbon 10 of dihydroartemisinin, while the art...

The nature of hemolytic effect induced by ethylene glycol alkyl ethers was analyzed taking into account G-6-PDH activity, ATP, pyruvate and thiols levels in peripheral blood of rats treated with single doses of 2-ethoxyethanol and 2-butoxyethanol. In addition, the susceptibility to autoxidation of rat erythrocyte lipids was evaluated. A decrease of ATP level in a dose-dependent manner and an in...

Glycol ethers have been widely used since the 1960s as solvents and stabilizers in a variety of personal, household, and industrial products. A new study in Environmental Health Perspectives provides some of the first evidence of associations between prenatal exposures to glycol ethers and cognitive impairments in children.These chemicals are generally valued for their low acute toxicity. Howev...

Linear alkyl ethoxylates (polyethylene glycol alkyl ethers) were fermented completely to methane and CO2 in enrichment cultures inoculated with anoxic sewage sludge. Long-chain fatty acids were released as intermediates. No degradation was found with polypropylene glycol and polypropylene glycol-containing surfactants. Two types of primary ethoxylate-degrading bacteria were isolated and charact...

The study of the interaction of three glycol ethers, i.e. 2-methoxyethanol (ME), 2-ethoxyethanol (EE) and 2-butoxyethanol (BE) administered subcutaneously for 4 weeks and ethanol simultaneously given as 10% w/v solution for drinking in male rats, was carried out from a toxicodynamic point of view. Administered alone, ME (2.5 and 5.0 mM/kg), EE (2.5 and 5.0 mM/kg) or BE (0.75 and 1.25 mM/kg) res...
