We have developed a quantitative structure-activity model for the variations in potency among the nitrosamines and, more recently, a related model for the variation in target organ for a smaller set of nitrosamines. We are currently developing a model for interspecies variation in susceptibility toward carcinogenic nitrosamines. The model for organ selectivity requires terms for the parent nitrosamine as well as for the hypothesized metabolites while the model for potency variations contains terms only for the unmetabolized parent compound. [Pg.77]

Our approach is to examine small, closely-related series of nitrosamines and to develop structure-activity models based on molecular descriptors which are explicitly meaningful with respect to the organic chemistry and biochemistry of the compounds. The forms of these models can then often be interpreted in terms of the mechanisms through which these compounds exert their carcinogenic effects. [Pg.77]

We recently reported a structure-activity model for variations In target organs (12) and are currently examining the possible application of the quantitative structure-activity approach to the problem of specles-to-specles differences In susceptibility toward nltrosamlne carcinogenesis (19). These two topics will be discussed In the remainder of this presentation. [Pg.79]

There appears now to be ample evidence that the variations in carcinogenicity among the nitrosamines are systematically and rationally related to structure and that several Indices of carcinogenic potency can be used as indices of biological response for the generation of quantitative structure-activity models (11-17). [Pg.85]

Ultrafiltration of heterogenous colloidal suspensions such as citrus juice is complex and many factors other than molecular weight contribute to fouling and permeation. For example, low MW aroma compounds were unevenly distributed in the permeate and retentate in UF in 500 kd MWCO system (10). The authors observed that the 500 kd MWCO UF removed all suspended solids, including pectin and PE. If PE is complexed to pectate in an inactive complex, then it is conceivable that release of PE from pectin with cations will enhance permeation in UF. At optimum salt concentration, less PE activation was observed at lower pH values than at higher pH (15). In juice systems, it is difficult to separate the effect of juice particulates on PE activity. Model studies with PE extracts allows UF in the absence of large or insoluble particulates and control of composition of the ultrafilter. In... [Pg.478]

In order to construct new types of binding and activating models of dioxygen molecules, Jitsukawa, Masuda and their co-workers have synthesized a novel group of tripodal tetradentate ligands and successfully utilized them in the formation of mononuclear copper(II) complexes with novel structural features (complexes (473)-(488)).395-403 This group of ligands has four... [Pg.835]

The better known rhenium(V) chemistry is of great interest, not only because it resembles the second-row congener technetium and easily permits non-radio-active model studies for technetium. 186Re and 188Re are attractive isotopes for therapeutic radiopharmaceuticals. 99mTc and 186Re can be considered to be a matched pair for diagnostics and therapy. [Pg.82]

The modeler should also take heart that his work provides an impetus to determine more accurate thermodynamic data, derive better activity models for electrolyte solutions, and measure reaction rates under more realistic conditions. [Pg.26]

Helgeson (1969 see also Helgeson and Kirkham, 1974) presented an activity model based on an equation similar in form to the Davies equation. The model, adapted from earlier work (see Pitzer and Brewer, 1961, p. 326, p. 578, and Appendix 4, and references therein), is parameterized from 0°C to 300 °C for solutions of up to 3 molal ionic strength in which NaCl is the dominant solute. The model takes it name from the B-dot equation,... [Pg.119]
