A series of substituted ( Z)-5-( N-benzylindol-3-ylmethylene)imidazolidine-2,4-dione ( 3) analogs structurally related to aplysinopsin, and that incorporate a variety of substituents in both the indole and N-benzyl moieties have been synthesized under microwave irradiation and conventional heating methods. These analogs were evaluated for their anti-proliferative activity against MCF-7 and MDA-231 breast cancer cell lines, and A549 and H460 lung cancer cell lines. Two analogs, 3f and 3j had IC 50 values of 4.4 and 5.2 μM, respectively, compared to 5-fluorouracil (IC 50 = 15.2 μM) against MCF-7 cells.
