Abstract
Glioblastoma multiforme (GBM) is the most common and primary brain tumor with poor prognosis. They are removed by following tedious and life threatening surgeries. GBM stem cells (GSCs) are the main source of tumor recurrence after surgery. Hence, drugs are designed to overcome the recurrent glioblastoma malignant cells. Currently used chemotherapies are not cost effective as well as bear resistance. New and effective chemotherapeutic compounds are developed to overcome the intrinsic and acquired resistance. Dicoumarol derivative 3,3'-[(4-methoxyphenyl)methanediyl]bis(4-hydroxy-2Hchromen-2-one) (HL) and its triethylammonium salt triethylammonium3-[(4-methoxyphenyl)(4-hydroxy-2-oxo-2H-chromen-3-yl)methyl]-2-oxo-2H-chromen-4-olate (L) were synthesized and characterized using spectral and analytical techniques. The deprotonated compound L was further studied structurally using single crystal analysis. Cytotoxic studies against human glioblastoma cells A172 and LN229 were investigated both dose and time dependently and compared with the cytotoxicity of normal human astrocytes (NHA). The IC50 value of HL against A172 was found to be lying within the range 2.68-0.95 μM whereas against LN229 the range was found to be 9.55-0.85 μM. Similarly, the compound L revealed range of 1.9-0.271 μM against A172 and 1.2-0.27 μM against LN229. Cell cycle arrest was observed in GBM cells treated with L compared to the control group, which suggested that L may trigger apoptosis in GBM cells according to cytotoxicity and flow cytometry results. The antioxidant activity of synthesized compounds was also investigated using DPPH free radicals.
