2-((Benzimidazol-2-yl)thio)-1-arylethan-1-ones: Synthesis, crystal study and cancer stem cells CD133 targeting potential

2-((Benzimidazol-2-yl)thio)-1-arylethan-1-ones 5a-o were synthesized to evaluate their activities towards colon HT-29 cancer cell line and the cell surface expression of CD133, a potent cancer stem cells (CSCs) marker.
