Abstract

The dietary carcinogen 2-amino-1-methyl-6-phenylimidazo(4,5-b)pyridine (PhIP) is a heterocyclic amine and is a common byproduct of cooked meat and fish. Although most cells undergo apoptosis when exposed to this mutagen, subsets develop resistance. Rather than die, these resistant cells persist and accumulate mutations, thereby driving tumorigenesis of exposed organs within the gastrointestinal tract. By applying a high-throughput cell-based screen of 32,000 small molecules, we have identified a family of compounds that specifically inhibit the growth of PhIP-resistant cancer cells. These compounds may prove useful for the treatment or prevention of gastrointestinal tumors arising after exposure to PhIP and related carcinogens.
