The major active constituent of Camptotheca called camptothecin is known to be effective in treating cancer. This element actually slows down the secretion of topoisomerase I, an enzyme related to cell division as well replication of the DNA. It has been found that camptothecin actually stunts the growth of tumours by slowing down the production of this particular enzyme.

Several other anti-cancer drugs have been developed using camptothecin and two among these have even been approved by the United States Food and Drug Administration (FDA) for sale and use to treat different forms of cancer. While the prescription drug Topotecan, which has been modified from camptothecin, is given to patients suffering from ovarian and small lung cancers, the other medication developed from camptothecin is irinotecan, which is used to treat metastatic colorectal cancer (a form of cancer which develops in the colon or rectum and subsequently extends to other parts of the body). In effect, today metastatic colorectal cancer is the second most important cause of deaths owing to cancer in the United States. It may be noted here that other anti-cancer drugs developed from camptothecin are not used any longer owing to their acute toxicity.
