Background and Objective: 2,4 dinitrophenol is observed in sewage produced from chemical and petrochemical industries. Contamination of drinking water with these pollutants causes toxicity, health problems and change in taste and odor. The present study was developed to evaluate the efficiency of removal 2,4-DNP through dried sludge adsorbent and modified calcium chloride sludge adsorbent. M...
BACKGROUND Non-steroidal anti-inflammatory drugs (NSAIDs) cause gastrointestinal damage by a non-prostaglandin (PG) dependent "topical" action and by inhibiting cyclooxygenase. AIMS To discriminate between these two effects by studying some key pathophysiological steps in NSAID enteropathy following administration of (R)- and (S)-flurbiprofen, the racemic mixture, and an uncoupler, dinitrophe...
It was concluded in a previous paper (1) that the enhancement of respiration by inorganic orthophosphate, occurring in rat liver mitochondria oxidizing a number of Krebs cycle metabolites or glutamate in the presence of 2,4-dinitrophenol or Dicumarol, is due to the substrate level phosphorylation linked to the oxidation of a-ketoglutarate which is not uncoupled by these agents. Yet, no requirem...

The effects of several inhibitors on the rates of photosynthesis and of respiration by Chlorella pyrenoidosa have been studied. The inhibitors used in this study include potassium cyanide, hydroxylamine hydrogen chloride, dinitrophenol,and sodium azide. Each inhibitor seems to have its own characteristic action in photosynthesis and in respiration. With the exception of hydroxylamine, all the i...
A supramolecular cocrystal of 2-ammino-5-nitropyridine (ANP) with 2,4-dinitrophenol (DNP) has been successfully grown by the slow evaporation solution growth technique. The crystal structure 2-amino-5-nitropyridine-2,4-dinitrophenol (ANDP) was elucidated single-crystal X-ray diffraction analysis, and it belongs to a monoclinic system centrosymmetric space group P21/n. bulk phase purity homogene...
background: phenol and its derivatives like dinitrophenol and pentachlorophenol (carbolic acid) are widely used as insecticides, but they are very toxic substances. phenol is a general protoplasmic poison with corrosive local effects that denature proteins. poisoning with phenol compounds may occur by ingestion, inhalation, and absorption through skin. in this report we presented the toxicity e...
