Cyclosativene (CSV) is a tetracyclic sesquiterpene found in the essential
oils of Centaurea cineraria (Asteraceae) and Abies magnifica A. Murray
(Pinaceae) plants. To the best of our knowledge, its cytotoxic, genotoxic and
oxidant effects have never been studied on any cell lines. Therefore, we
aimed to investigate the in vitro antiproliferative and/or cytotoxic
properties, antioxidant/oxidant activity and genotoxic damage potential of
CSV in healthy neurons and N2a neuroblastoma (N2a-NB) cell cultures. After
treatment with 10-400 μg/ml of CSV for 24 h, cell proliferation was measured
by the MTT (3,(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide)
assay. The antioxidant activity was assessed by the total antioxidant
capacity (TAC) and total oxidative stress (TOS) assays. To evaluate the level
of DNA damage, single cell gel alkaline electrophoresis (SCGE) was used. The
MTT assay showed that the application of CSV significantly reduced cell
viability in both cell types. CSV treatments at higher doses led to decreases
of TAC levels and increases of TOS levels in neuron and N2a-NB cells. The
mean values of the total scores of cells showing DNA damage were not found to
be significantly different from the control values in both cells. In
conclusion, this study suggests that CSV has weak anticancer potential.
