Abstract

Background

Ovarian cancer, also known as a silent killer, is the deadliest gynecological cancer in women worldwide. Epithelial ovarian cancers constitute the majority of ovarian cancers, and diagnosis can be made in advanced stages, which greatly reduces the likelihood of treatment and lowers the survival rate. For the treatment of epithelial ovarian cancers, the search for synthetic agents as well as agents of natural origin continues. The effects of 1-(2-cyanobenzyl)-3-(4-vinylbenzyl)-1H-benzo[d]imidazole-3-ium chloride (BD), a benzimidazole derivative, were investigated on epithelial ovarian cancer cells.

Methods and results

In our study, the effects of BD on proliferation, colony formation, cell death by apoptosis and the cell cycle in A2780 and A2780 Adriamycin (ADR) ovarian cancer cell lines were investigated. Proliferation was examined with cell viability analysis, colony formation and apoptosis with Annexin V staining and cell cycle analyses with PI staining, respectively. As a result of the analyses, BD inhibited cell proliferation and colony formation, induced apoptosis and cell death at 48 h in A2780 and A2780 ADR cells at 10.10 and 10.36 µM concentrations, respectively. In addition, A2780 and A2780ADR cells were arrested in the Sub-G1 phase of the cell cycle.

Conclusions

BD suppresses cancer cell progression by showing antiproliferative effects on ovarian cancer cells. Further analyses are required to determine the mechanism of action of this agent and to demonstrate its potential as a suitable candidate for the treatment of epithelial ovarian cancer.
