In this study, the potential antitumor activity of an essential oil (EO) obtained from Thymus vulgaris L. plants cultivated in Campania (Southern Italy) was evaluated. The gas chromatography-mass spectrometry and Fourier transform infrared spectroscopy were used to investigate the chemical composition of EO. The monoterpenes thymol, p-cymene and carvacrol are the more abundant compounds detected. The anti-proliferative activity of the EO as a function of dose and time of exposure was evaluated by MTT assay on human osteosarcoma U2OS and pancreatic cancer PANC-1 cell lines. EO inhibits proliferation of both cell lines, but the effect on PANC-1 cells was more extensive. Flow cytometry and Western blot analyses revealed that the anti-proliferative effect is due to a decrease of cells in the S phase and their accumulation in the G1 phase, associated with the decrease of cyclin A and the increase of cell cycle inhibitor p27 protein levels, respectively.

Abstract

In this study, the potential antitumor activity of an essential oil (EO) obtained from Thymus vulgaris L. plants cultivated in Campania (Southern Italy) was evaluated. The gas chromatography-mass spectrometry and Fourier transform infrared spectroscopy were used to investigate the chemical composition of EO. The monoterpenes thymol, p-cymene and carvacrol are the more abundant compounds detected. The anti-proliferative activity of the EO as a function of dose and time of exposure was evaluated by MTT assay on human osteosarcoma U2OS and pancreatic cancer PANC-1 cell lines. EO inhibits proliferation of both cell lines, but the effect on PANC-1 cells was more extensive. Flow cytometry and Western blot analyses revealed that the anti-proliferative effect is due to a decrease of cells in the S phase and their accumulation in the G1 phase, associated with the decrease of cyclin A and the increase of cell cycle inhibitor p27 protein levels, respectively.
