When activated by an acylating agent, pyridine boronic esters react with organometallic reagents to form a dihydropyridine boronic ester. This intermediate allows access to a number of valuable substituted pyridine, dihydropyridine, and piperidine products.
Synthesis of N-arylpyridinium salts bearing a nitrone spin trap as potential mitochondria-targeted antioxidants
Robertson, Linsey,Hartley, Richard C.
experimental part, p. 5284 - 5292 (2009/11/30)
The generation of excess reactive oxygen species (ROS) in mitochondria is responsible for much of the oxidative stress associated with ageing (aging), and mitochondrial dysfunction is part of the pathology of neurodegeneration and type 2 diabetes. Lipophilic pyridinium ions are known to accumulate in mitochondria and this paper describes a general route for the preparation of nitrone-containing N-arylpyridinium salts having a range of lipophilicities, as potential therapeutic antioxidants. The compatibility of nitrones with the Zincke reaction is the key to their synthesis. Their trapping of carbon-centred radicals and the EPR spectra of the resulting nitroxides are reported.
BIS-PYRIDINIUM COMPOUNDS
-
Page/Page column 23-24, (2008/06/13)
A method of treating, inhibiting, or preventing an infection in a subject is described. The method comprises administering to the subject an effective amount of at least one bis-pyridinium compound. The bis-pyridinium compound comprises two aromatic ring structures. Each of the ring structures comprises a pyridine ring, and the ring structures are linked by a linker group of at least 8 atoms in length, said linker group being attached to the nitrogen atoms of the pyridine rings. At least one substituent on at least one of the ring structures is an alkyl group having at least 2 carbon atoms, and no substituent on either of the ring structures is -OH, -SH or an amine group.
