The effects of lonidamine on membrane electrical properties of Ehrlich ascites tumor cells are investigated. Using a dielectric relaxation technique based on the Maxwell-Wagner effect and elaborated by a 'single-shell' fitting procedure, the data indicate that both membrane conductivity and membrane permittivity increase after treatment of these cells with lonidamine while the conductivity of the cytosol remains unchanged. Changes in membrane proteins and/or lipids are suggested which lead to altered membrane structure and/or function.

UI MeSH Term Description Entries
D007191 Indazoles A group of heterocyclic aromatic organic compounds consisting of the fusion of BENZENE and PYRAZOLES. Indazole
D008297 Male Males
D008564 Membrane Potentials The voltage differences across a membrane. For cellular membranes they are computed by subtracting the voltage measured outside the membrane from the voltage measured inside the membrane. They result from differences of inside versus outside concentration of potassium, sodium, chloride, and other ions across cells' or ORGANELLES membranes. For excitable cells, the resting membrane potentials range between -30 and -100 millivolts. Physical, chemical, or electrical stimuli can make a membrane potential more negative (hyperpolarization), or less negative (depolarization).
