The life grid, has recently been acclaimed as a accurate method for collecting retrospective data from elderly respondents. Accounts of using this method, which are based upon quantitative studies, however, have not adequately captured the dynamics of grid interviewing. This is, we suggest, because it is much easier to describe technical aspects of a research method than it is to convey how that method works in practice. In this article we set out to portray some of these more ‘indeterminate’ aspects of the life grid interviewing, drawing on our own experiences of using this method in an qualitative study of lifecourse patterns of smoking behaviour among elderly respondents who have a smoking related illness. Focussing upon interaction between researcher and respondent the article explores the reconstruction of the life course as a mutual endeavour and the implications of this for the interview structure and data collection among this respondent group.
The triarylethylene antiestrogen clomiphene was previously shown to undergo biotransformation to an active metabolite, 4-hydroxyclomiphene, and to 3-methoxy-4-hydroxyclomiphene plus the respective regioisomers of these, 4 and 5. We now report the synthesis and further chemical and biochemical studies on 3-5. Coupling of 4-[2-(diethylamino)ethoxy]benzophenone with either 4-(benzyloxy)benzaldehyde or its 3-methoxy analogue 11b in the presence of titanium, followed by chlorination and deprotection of the intermediate triarylethylenes, gave 4 and 5, respectively. Condensation of benzylmagnesium chloride with the (2-methoxyethoxy)methyl (MEM) ether of 4-[2-(diethylamino)ethoxy]-3'-methoxy-4'-hydroxybenzophenone, followed by mild acid treatment, afforded deschloro 3 due to facile MEM ether hydrolysis. Acetylation of this, followed by chlorination and deacetylation, gave 3. Compounds 4 and 5 reacted readily with nucleophiles. In particular, 2-mercaptoethanol reacted with 4 to afford deschloro vinyl thioether 13 as suggested by NMR spectral studies, a result that implicated allene-quinone 14 as the electrophilic species produced in solution from 4. Antiestrogen binding sites and estrogen receptors from MCF 7 human breast cancer cells interacted with 3 and 5 with affinities comparable to those of tamoxifen and 1, respectively; 5 was shown not to bind irreversibly with these sites. Inhibition of MCF 7 cell proliferation by 3-5 at 5 microM concentrations (76%, 57%, and 49%, respectively, relative to drug-free controls) compared favorably to that observed with 5 microM 1 (80%). These results suggest that 3-5 as well as 2 may contribute to the antiestrogenic effects of 1.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
