the aqueous electrochemistry of a number of anthraquinone derivatives was studied by using cyclic voltammetry at the surface of carbon paste electrode (cpe). from measurements of the half-wave potential as a function of ph, the potential - ph diagrams were constructed for each compound. the values of formal potentials and the pk'a of some different redox and acid-base couples involved in each c...

1. The involvement of intracellular 3':5'-cyclic AMP in the inhibition of platelet aggregation by prostaglandin E(1), isoprenaline and adenosine has been examined by a radiochemical technique. Platelet-rich plasma was incubated with radioactive adenine to incorporate (14)C radioactivity into platelet nucleotides. Pairs of identically treated samples were taken, one for the photometric measureme...

diolefinic antibacterial laser dye namely 1,4-bis[2-(4-pyridyl) vinyl] benzene (4pvb)have been investigated electrochemically using cyclic voltammetry, chronoamperometry, convolution and deconvolution voltammetry combined with digital simulation techniques at a platinum electrode in 0.1 mol / l tetra butyl ammonium perchlorate (tbap) in  solvent 1,2-dichloroethane.  the diolefinic species were ...
