, p. 738 - 743 (1996)
Two new benzyl-aporphine dimers, faurine (1) and its O-methyl ether (2), were obtained from Thalictrum fauriei and their structures determined by spectral and chemical methods. Faurine (1), the first dimer with the diphenyl ether connection at C-1 of the aporphine, did not undergo a Hofmann degradation, yet formed a chiral phenanthrene product (6) with cyanogen bromide. Two nondimeric chiral aporphine alkaloids, O-acetylisocorydine and O-methylisocorydine, gave the corresponding phenanthrene products 7 and 8, respectively, under the same conditions, but only compound 7 was optically active.
ELECTROCHEMICALLY ACTIVE AGENTS FOR PH MODULATION IN BIOLOGICAL BUFFERS
-
Paragraph 00304, (2017/01/26)
Device and methods for use in a biosensor comprising a multisite array of test sites, the device and methods being useful for modulating the binding interactions between a (biomolecular) probe or detection agent and an analyte of interest by modulating the pH or ionic gradient near the electrodes in such biosensor. An electrochemically active agent comprising quinone derivatives that is suitable for use in biological buffers for changing the pH of the biological buffers. Method for changing the pH of biological buffers using the electrochemically active agents. The methods of modulating the binding interactions provided in a biosensor, analytic methods for more accurately controlling and measuring the pH or ionic gradient near the electrodes in such biosensor, and analytic methods for more accurately measuring an analyte of interest in a biological sample.
