Abstract

Abstract: Chemotherapy is an important treatment modality for malignancy but is limited by significant toxicity and it susceptibility to numerous drug interactions. While the interacting effects with medications are well known, there is limited evidence on the interaction with commonly consumed food and natural products. The aim of this study was to evaluate the bioactive constituents of coffee (caffeine and chlorogenic acid) on the cytotoxicity of doxorubicin, gemcitabine, and paclitaxel in vitro . Pretreatment with caffeine (100 nM and 10 μM) sensitized SH-SY5Y cells to doxorubicin-induced toxicity and increased apoptosis and sensitized PC3 cells to gemcitabine-induced toxicity. Pretreatment with 10 μM caffeine decreased total cell reactive oxygen species (ROS) production but increased mitochondrial ROS production. In contrast, caffeine (10 nM and 10 μM) protected cells against gemcitabine-induced toxicity and apoptosis. Similarly, 1 μM and 10 μM caffeine protected cells against paclitaxel-induced toxicity and mitochondrial ROS production. Chlorogenic acid had no effect on chemotherapy-induced toxicity in SH-SY5Y cells. In conclusion, this study provides preliminary evidence that caffeine, not chlorogenic acid, modulates the cytotoxicity of doxorubicin, gemcitabine, and paclitaxel in SH-SY5Y cells via different mechanisms.
