General description

Electrochemical oxidation of 3-methylpyridine (3-MP) at synthetic boron-doped diamond (BDD) thin film electrode has been investigated by cyclic voltammetry and bulk electrolysis. 3-Methylpyridine forms adduct with 2,6-dichloro-4-nitrophenol and the structure of adduct has been determined by X-ray diffraction.

Tumor recurrence after chemotherapy is a major cause of patient morbidity and mortality. Recurrences are thought to be secondary to small subsets of cancer cells that are better able to survive traditional forms of chemotherapy and thus drive tumor regrowth.
