Purpose: The aim of this study was to evaluate the cytotoxic, phototoxic, genotoxic and photogenotoxic potential of gemifloxacin mesylate (GFM), its main synthetic impurity (SI) and one isolated and structurally elucidated degradation product (DP).
Methods: The neutral red uptake (NRU) and reduction of 2,5-diphenyl-3,-(4,5-dimethyl-2-thiazolyl)tetrazolium bromide (MTT) assays were performed as in vitro endpoints to evaluate cytotoxicity and phototoxicity in a 3T3 cell line, and predict toxicity and/or phototoxicity after systemic administration of the drug. The in vitro alkaline single-cell electrophoresis (comet) assay was used to evaluate the genotoxic and photogenotoxic potential of the substances using the same cell line.
