A series of polyhalo heterocyclic ketene aminals (polyhalo-HKAs) were synthesized under solvent-free conditions and evaluated in vitro against a panel of human tumor cell lines. Trifluoro-HKAs were the most cytotoxic compounds, followed by difluoro-HKAs and trichloro-HKAs. Trichloro-HKAs were more potent against the tumor cell lines Skov-3, Hep-2, K562, and A431 than difluoro-HKAs. An ethoxycarbonyl at the 2-position of the polyhalo HKAs gave the highest activity. Ethoxycarbonyl substituted 5o, bearing three fluorine atoms on the isophthalonitrile ring, was found to be the most potent derivative with IC50 values lower than 3.7 μg/mL against five human tumor cell lines making it more active than cisplatin (DDP).
