Properties carcinogenic

Pale yellow crystals, m.p. 179°C. A constituent of coal tar with strong carcinogenic properties. 

Used industrially to cross-link hydroxylic polymers, polyethyleneimine. Possesses some carcinogenic properties. Polyethyleneimine is a hygroscopic liquid used in paper manufacture to confer wet strength and in textiles, alkylated derivatives also form useful polymers. 

CAUl lON. This compound has carcinogenic properties and great care should be taken to avoid all contact with it during its isolation and drying. 

Factors which may affect the cost of coal upgrading are environmental considerations such as toxicity, hazardous waste disposal, and carcinogenic properties (131). These and other environmental problems from process streams, untreated wastewaters, and raw products would figure significantly into the cost of commercialization. 

Other fibrous and porous materials used for sound-absorbing treatments include wood, cellulose, and metal fibers foamed gypsum or Pordand cement combined with other materials and sintered metals. Wood fibers can be combined with binders and dame-retardent chemicals. Metal fibers and sintered metals can be manufactured with finely controlled physical properties. They usually are made for appHcations involving severe chemical or physical environments, although some sintered metal materials have found their way into architectural appHcations. Prior to concerns regarding its carcinogenic properties, asbestos fiber had been used extensively in spray-on acoustical treatments.

The carcinogenic properties of tricycloquinazoline (60) were studied in detail because of its possible formation from anthranilic acid derivatives in nature. It possessed stronger carcinogenic activity toward mice (72%) than rats (27%). Its action resembled that of embedded plastic materials, because it was recovered unmetabolized. ... 

Because of the number of citations, only selected imidazoquinolines are described, and biological activity is mentioned only briefly. The largest increase in the number of citations was caused by the discovery of the antibacterial properties of nalidixic acid type drugs. Efforts to prepare the bioisosters, for example of oxolinic acid, intensified in the early 1970s, and the discovery of the carcinogenic properties of 2-aminoimidazoquinolines followed in the early 1980s. These azoloquinolines can be considered as benzene-separated deazapurines. 

The toxic properties of Pteridium aquilinum L., the common bracken fern, have been known to humankind for a very long time. Two principal causes of trouble are its carcinogenic properties (M. Saito et al., 1975 I. A. Evans, 1976 Hirono, 1986)... 

The class of Il-nitroso compounds (l e , nitrosamines and nitrosamides) is currently considered a unique group that includes members with remarkable carcinogenic properties. Because of their potency and almost ubiquitous presence in... 

Traditional octanol-water distribuhon coefficients are shll widely used in quan-titahve structure-achvity relationship (QSAR) and in ADM E/PK studies. However, alternahve solvent systems have been proposed [80]. To cover the variabihty in biophysical characterishcs of different membrane types a set of four solvents has been suggested, somehmes called the critical quartet [81]. The 1,2-dichloroeth-ane-water system has been promoted as a good alternative to alkane-water due to its far better dissolution properties [82, 83], but may find little applicahon because of its carcinogenic properties. 

P-Bromonaphthalene. The preparation from p-naphthylamine, which has carcinogenic properties, is avoided by the use of 2-naphthylamine-1-sulphonic acid ( 2-amino-1-naphthalenesulphonic acid ) the latter is obtained commercially by cautious treatment of p-naphthol with sulphuric acid—the SOjH group first enters the 1-position—followed by the Bucherer reaction. Diazotisation and reaction with cuprous bromide yields 2-bromonaphthalene-l-sulphonic acid heating with sulphuric acid eliminates the sulphonic acid group to give 2-bromonaphthalene. 

Although the correlation between structural properties of aromatic hydrocarbons and their carcinogenic properties proved to be much more complicated than was hoped, this type of calculation opened the door to the application of quantum chemistry to biological systems. The calculations are applied not only to cancer-related problems, but also to the study of amino acids, peptides, nucleotides, and other than anti-cancer therapeutic agents.
