Abstract

N-Acetylcysteine is currently being considered as a possible selective protector against pulmonary toxicity resulting from X-rays or chemotherapeutic treatment, but its clinical application awaits evidence that it does not interfere with the efficient killing of tumor cells. The capacity of N-acetylcysteine to protect against the antitumor activity of X-rays and of bleomycin was evaluated in a clonogenic cell-survival assay using SW-1573 human squamous lung carcinoma cells as a tumor model. Using the highest non-toxic dose of N-acetylcysteine (incubation for 2 days in the continuous presence of 10 mM) no effect on clonogenic cell killing by X-rays or bleomycin treatment could be detected, even though a twofold enhancement of endogenous glutathione was effectuated. Our data thus indicate that clinically relevant concentrations of N-acetylcysteine are incapable of protecting tumor cells against clonogenic killing by X-rays and by bleomycin.
