Double-barreled K+-selective microelectrodes based on dibenzo-18-crown-6.
Am. J. Physiol. 255(3 Pt 1) , C408-12, (1988) Liquid ion-exchanger microelectrodes based on Corning code 477317 K+ exchanger are known to be much more sensitive to quaternary ammonium ions than to K+. In the presence of such cations, the capability of measuring K+ activities with Corning microelectrodes ... |

On the mechanism of action of polyether XXVIII at site I of the electron-transfer chain in rat liver mitochondria.
Biochim. Biophys. Acta 638(1) , 125-31, (1981) In rat liver mitochondria, the macrocyclic polyether, dibenzo-18-crown-6 (polyether XXVIII) inhibits the oxidation of NAD-dependent substrates, as stimulated by ADP, uncouplers and valinomycin plus K+. It does not inhibit the oxidation of succinate. It is con... |
