In clinical settings it is widely believed that camptothecin analogs exhibited remarkable anti-tumor and anti-leukaemia activity.  Topoisomerase is a basilic enzyme in the process of DNA replication  responsible for the winding / unwinding of the super-coiled DNA composing the chromosomes.  If the chromosomes cannot be unwound, transcription of DNA messages cannot occur so that the protein cannot be synthesized, which ultimately causes cell death.

Application of camptothecin in clinical settings is limited due to serious side effects and poor water-solubility.  At present, some camptothecin analogs—either semi-synthetic or synthetic drugs based on camptothecin—have been applied as cancerous therapy such as topotecan and irinotecan, while others have obtained satisfying curative effects in clinical applications.
