Cytotoxic effects of hydroxy coumarin derivations to neuroblastoma N2a cells

Neuroblastoma is one of the nervous system cancers, which approximately consists of 9% of childhood cancers. In this study, we evaluated the toxic effects of prenyl hydroxy coumarin derivatives on apoptosis of the neuroblastoma cell line N2A. N2a cells were cultured in DMEM medium, then the effects of different concentrations (0.75–200 μg/mL) of prenyl hydroxy coumarin derivatives during 24, 48, and 72 h were studied. Cell viability was quantified by MTT assay; apoptotic cells were determined using PI staining of DNA fragmentation by Flow cytometry (sub-G1 peak). The toxic effect of 3- farnesyl oxi coumarin in the N2A cell starts at 6.25 μg/ml and increases relatively depending on rising in concentration and time. The toxicity and apoptosis in 3- farnesyl and 6- farnesyl oxi coumarin is more than 3- Geranyl and 6-Geranyl oxi coumarin. Prenyl hydroxy coumarin induces peak sub-G1in flow cytometry compared to the control group, indicating prenyl hydroxy coumarin-induced toxicity, which is involved in apoptotic cell death. Different concentration of hydroxy coumarin derivatives (0.75-200) µg/mL in lymphocytes, did not induce any anti-proliferative effect in 24 h. In conclusion, prenyl hydroxy coumarin derivatives induce apoptotic effects in the N2A cell line. Thus prenyl hydroxy coumarin derivatives sound to be chemotherapeutic agents for the neuroblastoma cancer cells.
