Synthesis of New 3-Arylisoquinolinamines: Effect on Topoisomerase I Inhibition and Cytotoxicity

  • Published : 2003.10.01

Abstract

Eukaryotic DNA topoisomerase I (top I) is an essential enzyme that act to relax supercoiled DNA during the transcription, replication and mitosis. Intracellular levels of top I are elevated in a number of human solid tumors, relative to the respective normal tissues, suggesting that controlling the topI level is important to treat cancer. Top I poisons show their antitumor activities by stabilizing the cleavable ternary complex consisting of top I enzyme, DNA, and drug. Thus, top I is a promising target for the development of new cancer chemotherapeutics against a number of solid tumors. (omitted)
