The title compound, C(26)H(18), consists of a benzene ring with meta-substituted 1-naphthalene substituents, which are essentially planar (r.m.s. deviation = 0.039 and 0.027 Å). The conformation is mixed syn/anti, with equivalent torsion angles about the benzene-naphthalene bonds of 121.46 (11) and 51.58 (14)°.

Two naphthalene-degrading bacteria, Pseudomonas putida G7 and Pseudomonas sp. strain NCIB 9816-4, were chemotactically attracted to naphthalene in drop assays and modified capillary assays. Growth on naphthalene or salicylate induced the chemotactic response. P. putida G7 was also chemotactic to biphenyl; other polyaromatic hydrocarbons that were tested did not appear to be chemoattractants for...

The anaerobic biodegradation of naphthalene, an aromatic hydrocarbon in tar and petroleum, has been repeatedly observed in environments but scarcely in pure cultures. To further explore the relationships and physiology of anaerobic naphthalene-degrading microorganisms, sulfate-reducing bacteria (SRB) were enriched from a Mediterranean sediment with added naphthalene. Two strains (NaphS3, NaphS6...

Previous studies have shown variability in naphthalene cytotoxicity, expression of CYP2F2 gene and protein, and naphthalene metabolism in random cycling female mice (NIH:Swiss). CYP2F2 metabolizes naphthalene to cytotoxic metabolites in lungs of mice. This study was designed to address the question: do hormonal changes associated with the estrous cycle alter metabolism of naphthalene in the lun...

In the macrocyclic title compound, C(26)H(12)Cl(2)N(6)O(4), an O-atom-bridged calix[2]naphthalene-[2]triazine synthesized using a one-pot approach from naphthalene-2,7-diol and cyanuric chloride, the two isolated naphthalene planes and the two triazine-2,6-di-oxy planes adopt a 1,3-alternate configuration, with a dihedral angle of 84.10 (8)° between the naphthalene rings and a dihedral angle of...

Bouchard and Charrin (1) have observed that the repeated administration of naphthalene to rabbits causes the formation of cataracts. Lesnick (2) has been able to isolate cr-naphthylglycuronate from the urine of dogs which were fed naphthalene. Edelfsen (3) and Igersheimer and Ruben (4) have confirmed the observation of Lesnick (2) by applying color reactions to the urine of dogs which were fed ...

Naphthalene (NA) is metabolized to highly reactive intermediates that are primarily detoxified by conjugation to glutathione (GSH). Intraperitoneal administration of naphthalene causes substantial loss of both hepatic and respiratory GSH, yet only respiratory tissues are injured in mice. The liver supplies GSH to other organs via the circulation, making it unclear whether respiratory GSH losses...

Naphthalene AA-Final, a naphthalene preparation, is a new tool in the management of psoriasis. Brown naphthalene has been used for 15 years in the treatment of psoriasis at Special Hospital for Medical Rehabilitation in Ivanic Grad, Croatia. Naphthalene is obtained from naphtha, a complex mixture of various compounds, mostly hydrocarbons. Naphthalene AA-Final is a new naphthalene preparation en...
