We synthesized a series of novel 3-indolyl cyclopent[b]indoles by trifluoroacetic acid mediated cyclodimerizations. The reaction showed high stereoselectivity and moderate to good yields. The influencing factors for stereoselectivity were systematically analyzed and a stepwise reaction mechanism was proposed. The cell viability tests in two colon and two lung cancer cell lines indicated the 1-benzyl-2-phenyl-group in 3-indolyl cyclopent[b]indoles was critical for the observed lower IC50s in these compounds. Western blot analysis demonstrated that the compound inhibited the expression and phosphorylation of EGFR through altered HSP90 expression. Further cell cycle and cell cycle check point protein analyses showed expected anti-cellular proliferation and cell cycle arresting properties associated with suppressed EGFR expression and phosphorylation. These data revealed a novel molecular mechanism explaining the observed cytotoxicities for these compounds.
