Aim:
To find new anticancer drug based on the structure of 10-hydroxy camptothecin.
Methods:
Seven camptothecin derivatives (3 -9) were synthesized and the antitumor activities of these derivatives were evaluated.
Results:
Structures of seven new compounds were determined by 1HNMR, IR, MS. Seven compounds showed inhibitory effects on Hela, BEL-7402, 7901 cell lines in vitro. Especially, compound 4 showed high bioactivities to all of the tumor cells in vitro, its anticancer activity against human cervical carcinoma Hela was much higher than that of 10-hydroxy camptothecin.
Conclusion:
Some compounds are worth further studying.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
