11-Phenyl-[b,e]-dibenzazepine compounds: novel antitumor agents.

Abstract A series of 11-phenyl-[ b , e ]-dibenzazepine compounds were synthesized and shown to be inhibitors of tumor cell proliferation with IC 50 values ranging from submicromolar to micromolar concentrations. Flow cytometric analyses of several active compounds demonstrated inhibition of cell cycle progression at the G 0 –G 1 phase transition resulting in G 0 –G 1 arrest.
