Abstract
Although chlorpromazine was shown to greatly inhibit a Ca2+-mediated cell death at favorable concentrations (10-6 ∼ 10-5 M), it caused a drastic decrease in cell viability at higher concentrations (10-4 ∼ 10-3 M) in a human neuroblastoma cell line. The toxic effect of chlorpromazine also occurred in Ca2+-free medium and was not parallel to the amount of thiobarbituric acid-reactive substances produced. These results indicate that chlorpromazine has biphasic effects on cell viability according to the concentrations added, i.e. a protective effect against cell damage caused by Ca2+, and a direct toxic effect independent of extracellular Ca2+ or of lipid peroxidation.
