Identification of nitroso compounds from biotransformation of 2,4-dinitrotoluene.
The intermediates of microbial transformation of 2,4-dinitrotoluene by a mixed bacterial culture derived from activated sludge were identified as 2-amino-4-nitrotoluene, 4-amino-2-nitrotoluene, 2-nitroso-4-nitrotoluene, and 4-nitroso-2-nitrotoluene. The biotransformation of 2,4-dinitrotoluene occurred only under anaerobic conditions with an exogenous carbon source. The two nitroso compounds wer...
متن کاملDegradation of human hemoglobin by organic C-nitroso compounds.
The crystal structure of the nitrosomethane adduct of human Hb shows N-binding of the MeNO ligands to heme Fe. The structure of the EtNO adduct reveals a surprising 4.9 Å heme slippage in the β subunit, and explains the ability of C-nitroso compounds to degrade Hb removing it from circulation.
متن کاملDecontamination and disposal of nitrosoureas and related N-nitroso compounds.
An improved procedure for chemically decontaminating residues of nitrosoureas and related N-nitroso compounds ("nitrosamides") commonly used in the cancer research laboratory is proposed. Treatment of accumulated wastes with aluminum:nickel alloy powder while progressively increasing the basicity of the medium consistently led to at least 99.98% destruction of each nitrosamide tested. Hazardous...
متن کاملPlasma nitroso compounds are decreased in patients with endothelial dysfunction.
OBJECTIVES We investigated whether plasma nitros(yl)ated species (RXNOs) that mediate systemic nitric oxide (NO) bioactivity are depleted in individuals with cardiovascular risk factors and endothelial dysfunction. BACKGROUND Endothelium-derived NO acts not only as a regional messenger but exerts significant systemic effects via formation of circulating RXNOs delivering NO to sites of impaire...
متن کاملN-Nitroso compounds and childhood brain tumors: a case-control study.
We questioned mothers of 209 young brain tumor patients and mothers of 209 controls about experiences of possible etiological relevance which they had during pregnancy or which their children had while growing up. Long-suspected brain tumor risk factors such as head trauma and X-rays appeared to be factors for relatively few cases. Increased risk was associated with maternal contact with nitros...
