Dual acting antioxidant A1 adenosine receptor agonists
Gregg, Alison D., Bottle, Steven E., Devine, Shane M., Figler, Heidi, Linden, Joel, White, Paul, Pouton, Colin W., Urmaliya, Vijay, & Scammells, Peter J. (2007) Dual acting antioxidant A1 adenosine receptor agonists. Bioorganic & Medicinal Chemistry Letters, 17(9), pp. 5437-5441.
Herein we report the synthesis and biological evaluation of some potent and selective A1 adenosine receptor agonists, which incorporate a functionalised linker attached to an antioxidant moiety. N6-(2,2,5,5-Tetramethylpyrrolidin-1-yloxyl-3-ylmethyl)adenosine (VCP28, 2e) proved to be an agonist with high affinity (Ki = 50 nM) and good selectivity (A3/A1 400) for the A1 adenosine receptor. N6-[4-[2-[1,1,3,3-Tetramethylisoindolin-2-yloxyl-5-amido]ethyl]phenyl]adenosine (VCP102, 5a) has higher binding affinity (Ki = 7 nM), but lower selectivity (A3/A1 = 3). All compounds bind weakly (Ki > 1 μM) to A2A and A2B receptors. The combination of A1 agonist activity and antioxidant activity has the potential to produce cardioprotective effects.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
