The insertion of a -NO2 group onto the corrole framework represents a key step for subsequent synthetic manipulation of the macrocycle based on the chemical versatility of such a functionality. Here we report results of the investigation of a copper 3-NO2-triarylcorrolate in nucleophilic aromatic substitution reactions with "active" methylene carbanions, namely diethyl malonate and diethyl 2-ch...

background: no2 is a poisonous gas that potential to cause major threat to human being health and the environment, as a result, removing this gas from environment seems to be essential. methods: the study aimed to remove this gas from environment using iranian natural zeolite, clinoptilolite. after crushing and preparing two sizes of 1 and 2 mm zeolite they were activated in 380 to 420 ºc for 2...
Mn-Ce/FA (M) and Mn-Ce/FA-TiO2 (M), using fly ash (FA) with and without TiO2 as the carriers, were prepared by an integral molding technique. With the increase of TiO2 content, the rates of NO conversion and denitration of Mn-Ce/FA-TiO2 (M) increased, and the NO2 and N2O formation rates decreased. It is found that TiO2 could effectively inhibit the excessive oxidation of NO and the generation o...
We evaluated the airway irritation of isoprene, isoprene/ozone, and isoprene/ozone/nitrogen dioxide mixtures using a mouse bioassay, from which we calculated sensory irritation, bronchial constriction, and pulmonary irritation. We observed significant sensory irritation (approximately 50% reduction of mean respiratory rate) by dynamically exposing the mice, over 30 min, to mixtures of isoprene ...

Bacillus circulans xylanase contains two histidines, one of which (His 156) is solvent exposed, whereas the other (His 149) is buried within its hydrophobic core. His 149 is involved in a network of hydrogen bonds with an internal water and Ser 130, as well as a potential weak aromatic-aromatic interaction with Tyr 105. These three residues, and their network of interactions with the bound wate...
Our previous study showed that approximately one-third of the nitrogen of 15N-labeled NO2 taken up into plants was converted to a previously unknown organic nitrogen (hereafter designated UN) that was not recoverable by the Kjeldahl method (Morikawa et al., 2004). In this communication, we discuss metabolic and physiological relevance of the UN based on our newest experimental results. All of t...
