Investigation of Bioactivity of Estragole Isolated from Basil Plant on Brain Cancer Cell Lines Using Nuclear Method

Background In recent years, there has been a significant increase in studies investigating the potential use of plant-origin products in the treatment and diagnosis of different types of cancer. Methods In this study, Estragole (EST) was isolated from basil leaves via ethanolic extraction using an 80% ethanol concentration. The isolation process was performed using the High Performance Liquid Chromatography (HPLC) method. The EST isolated from the basil plant was radiolabeled with I-131 using the iodogen method. Quality control studies of the radiolabeled EST (I-131-EST) were carried out by using Thin Layer Radio Chromatography (TLRC). Next, in vitro cell, culture studies were done to investigate the bio-affinity of plant-originated EST labeled with I-131 on human medulloblastoma (DAOY) and human glioblastoma-astrocytoma (U-87 MG) cell lines. Finally, the cytotoxicity of EST was determined, and cell uptake of I-131-EST was investigated on cancer cell lines by incorporation studies. Results As a result of these studies, it has been shown that I-131-EST has a significant uptake on the brain cells. Conclusion This result is very satisfying, and it has encouraged us to do in vivo studies for the molecule in the future
