Cytotoxic activity properties of a benzimidazolium salt against lung, liver, and colon cancer cell lines

Abstract

In this study, a known benzimidazolium salt was synthesized in two steps starting from N-phenyl-o-phenylenediamine. This compound was tested in vitro for 72 h against different cancer cell lines (A549 - lung cancer, HepG2 - liver cancer, DLD-1 - colon cancer) and to compare the activity of this compound with cisplatin, a widely used chemotherapeutic agent. The evaluation of compound 4 as a potential anticancer agent against different cancer types was achieved by examining the cytotoxic effects of this compound through IC50 values using the MTT method. It was found that compound 4 showed different activity depending on the cell type and had a high cytotoxic effect (IC₅₀: 15.68 μM), especially against lung cancer cell line for 72 h incubation time.
