Beschreibung10-Hydroxycamptothecin: An Inhibitor of Topoisomerase I with Antitumor Activity10-hydroxycamptothecin (10-HCPT) is an inhibitor of topoisomerase I originally isolated from the Chinese tree C. acuminata. 10-HCPT, a member of the camptothecin family, interferes with DNA synthesis by inhibiting the enzyme topoisomerase-I and has a broad spectrum of antitumor activity and less toxicity as camptothecins. However, 10-HCPT is insoluble in both water and physiological acceptable organic solvents and tends to change into its carboxylate form, which shows minimal antitumor activity and several unpredictable side effects. Therefore, appropriate drug delivery systems (DDS) for 10-HPCT have been developed to improve the stability of its lactone form. 10-HCPT is also an important precursor for the synthesis of clinically useful anticancer agents, such as irinotecan[1].
