Design, synthesis and pharmacological evaluation of novel 2-chloro-3-(1<i>H</i>-benzo[<i>d</i>]imidazol-2-yl)quinoline derivatives as antitumor agents: <i>in vitro</i> and <i>in vivo</i> antitumor activity, cell cycle arrest and apoptotic response
A series of novel 2-chloro-3-(1H-benzo[d]imidazol-2-yl)quinoline derivatives were designed and synthesized as antitumor agents under the combination principle. The antitumor activity and mechanisms were then evaluated.
