Abstract

Topoisomerase I (top1) is a validated target for cancer chemotherapy (1-3) since its identification as the sole target of camptothecin (4). The sodium salt of camptothecin was found to be clinically active but its use was discontinued in the 70’s because of severe side effects and lack of understanding of the drug’s mechanism of action (5). The finding in 1985 that camptothecin specifically poisons top1 has generated great interest to find water-soluble, more efficacious and less toxic analogues of camptothecin.
