Voltammetric Behaviour of Metronidazole at Mercury Electrodes
Metronidazol é o fármaco mais importante do grupo de 5-nitroimidazoles, possuindo toxicidade contra microrganismos anaeróbicos, sendo a molécula de DNA o principal alvo de sua ação biológica. O mecanismo de ação do metronidazol depende do processo de redução do grupo nitro e, em meio ácido, a redução é pH-dependente envolvendo quatro elétrons na completa redução ao derivado hidroxilamínico. Em ...
متن کاملAcademic paediatrics: Easter Island or Easter Sunday?
W hen the last tree on Easter Island was felled, the inhabitants belatedly realised that there was no escape from an eon of ‘‘groundhog days’’. Paediatrics, a discipline championed in the UK, faces a comparably monotonous future bereft of innovation and improvement. Levene and Olver present alarming data on staffing changes in UK academic paediatrics between 1999 and 2004. Most worrying is a 26...
متن کاملElectroreduction of Some Diazine and Triazine Pesticides at the Dropping Mercury Electrode
Electroanalytical methods enable determination of electroactive species in nonhomogeneous systems, as limiting currents are little affected by the presence of solid and colloidal particles. An example of such applications of electrochemical methods are studies of binding of toxic substances, such as pesticides, on slightly soluble polymers, such as lignin. To successfully apply polarographic me...
متن کاملElectric-Field-Induced Transitions of Amphiphilic Layers on Mercury Electrodes
There are numerous examples in the literature of amphiphilic molecules which, when adsorbed onto mercury electrodes, undergo electric-field-induced transitions between different molecular conformations. In general, very sharp and reversible voltammetric features associated with these transitions are observed when the electrode potential is scanned in the negative direction, typically over the r...
