Despite advances in the treatment of head and neck squamous cell carcinoma (HNSCC), the morbidity remains at a high level due to the resistance of SCC cells to chemotherapeutics. This study aimed to determine and compare the magnitude of the flavonoids’ effectiveness in activating apoptosis and migration arrest in HNSCC cells in vitro. Methods: Head and neck SCC cells of the Detroit 562 line were exposed to a range of concentrations (5-100 µM) of quercetin (Que), hesperidin (Hes) and rutin (Rut) for 24 and 48 h. The SCC cell viability and migration rate were investigated using cytotoxicity and migration inhibition assays. Muse Cell Analyzer flow cytometry was utilized to quantitatively assess the apoptosis rate of Detroit 562 cells exposed to Que, Hes and Rut. The morphology of the SCC cells was evaluated via hematoxylin-eosin staining. Results: The viability diminishment of the Detroit 562-line cells treated with Que, Hes and Rut for 48 h revealed a significant dose-dependent trend, relatively equal for three substances, whereas the most noticeable cytotoxic effect observed for Hes. Exposure to Hes and Rut exhibited a dose-dependent increased proportion of apoptotic SCC cells, at either necrosis or late apoptosis stage. Detroit 562 SCC migration rate and cells motility were halted for the 100 µM dose of Hes and Que. The comparative results elucidated that Hesperidin and Quercetin achieved a more potent reduction of Detroit 562 migration at 24 h. Conclusions: Hesperidin, rutin and quercetin are capable of inducing apoptosis and migration arrest in the Detroit 562 cell line to various extents, resulting in proapoptotic attenuating effects at different magnitudes.
