Abstract


Chlorpromazine (CPZ) is still a commonly prescribed antipsychotic which causes poorly understood idiosyncratic toxicity such as cholestasis, phospholipidosis and steatosis. CPZ has diverse cellular targets and exerts various toxicity mechanisms whose exploration is necessary to understand CPZ side effects. We report here that CPZ causes a decrease of total lipid content in Saccharomyces cerevisiae at the same dose range as that used on mammalian cells. The observed lipid decrease was obvious after 4 and 9 hours of treatment, and disappeared after 24 hours due to cells adaptation to the chemical stress. The inhibitory effect of CPZ was antagonized by the antioxidant N-acetyl L-cysteine and is likely caused by the parent compound. The obtained results demonstrate that yeast model is valid to investigate the involved CPZ toxicity mechanisms, particularly in terms of lipids alteration. This would contribute to understand CPZ side effects in simple model and reduce experimentation on animals.
