| Description | 6-benzylaminopurine (6-BAP), one of the most important adenine type cytokinins (phytohormones), is very extensively studied because of their potential cytotoxic activity [1,2]. Dinuclear complexes of chlorinated and methoxylated derivatives of 6-benzylaminopurine with metal ions (Cu, Co, Fe, Pt and Pd) [3-5], are extensively studied as the possible enzyme inhibitors [6], anti-viral [7], anti-bacterial [8] and anti-cancer agents [9,10]. Some purines on the mercury and graphite electrodes in the presence of copper ions are able to form with monovalent copper, in situ formed from divalent copper on an electrode surface at slightly negative potentials, Cu (I)-purine complexes adsorbed on electrode surface and therefore the surface concentration of the purine base is increased (AdS technique)[11-15]. The aim of this contribution is the investigation of the oxidation behavior of BAP and its chlorinated derivatives on PeGE equipped by Tombow leads by using voltammetric methods, such as cyclic voltammetry (CV) and/or linear sweep voltammetry (LSV) completed with elimination voltammetric procedure (EVP; early EVLS) as a simple tool enabling not only the increasing of voltammetric signals, but also the sensitive revelation of adsorptive state of analytes and monitoring of the electrode processes accompanied by the complex formation [16,17]. For the study of substituent effect we explored not only BAP, but also its chlorinated derivatives. It is proved that a suitable graphite electrode for this research is a pencil embedded by leads Tombow (Japan). |
