Cytotoxic potential of selenium nanoparticles (SeNPs) derived from leaf extract of Mentha longifolia L.

The search for alternative methods in cancer treatments has been going on for many years. In the current study conducted for this purpose, selenium nanoparticles (ML-SeNPs) were produced from the aqueous leaf extract of Mentha longifolia L. easily and inexpensively, without harming the environment. The anticancer potential of ML-SeNPs on glioblastoma cell (U373), osteosarcoma cell (U2OS), and healthy retinal pigment epithelial cell (RPE-1) lines was determined by MTT (3-(4,5-dimetiltiazol-2-il)-2,5-difeniltetrazolium bromid) test. For the test, ML-SeNPs were applied at 100, 300, and 600 µg/mL levels and interaction was provided for 24 and 48 hours. The survival rates (%) in RPE-1, U373, and U2OS cell lines in the 24-hour application were 107.49-98.89, 97.66-86.82, and 87.81-83.37, respectively. The viability rates (%) of the cells in 48 hours of application were 72.27-87.39, 68.17-73.48, and 81.00-84.67, respectively. In general, it was discovered that the cytotoxic effect of ML-SeNPs on RPE-1, U373, and U2OS cell lines was greater at low doses and increased over time. In-vivo studies that support the antiproliferative action of ML-SeNPs may boost the prospect of using them as therapeutic agents in potential cancer treatment procedures in the following years.
