Topoisomerase enzymes are involved in the restructuring of DNA during synthesis to give other enzymes easy access to copy the two strands. DNA synthesis is an important step, occurring only when a cell is proliferating. Continual proliferation is a key characteristic of cancerous cells, and thus, topoisomerases are ideal targets for cancer therapeutics. Scientists are currently attempting to synthesize topoisomerase inhibitors that have differing target sites to more effectively eliminate cancer cells. Finding novel binding sites for inhibitors becomes paramount for overcoming drug resistance.

Scientists at Purdue University have developed novel compounds to inhibit Topoisomerase I that are intended to cease DNA synthesis and cause cell death. These inhibitors will be used as the primary treatment or in a synergistic manner to treat proliferating tumors. This innovation provides a novel, efficient, and scalable, synthetic route to these compounds that possess and express Top I inhibition and cytotoxicity.
