[Synthesis of camptothecin glycosides by phase transfer-catalysis and its inhibitory activity against topo I].
Yao Xue Xue Bao. 2005 Dec; 40(12):1116-21.YX

Abstract

AIM

To find new anticancer drug based on the structure of 10-hydroxy camptothecin.

METHODS

Six camptothecin glycosides (7-12) were synthesized by phase transfer catalysis. The structures of all compounds synthesized were determined by 1H NMR, IR and MS. Their antitumor activity was evaluated on cancer cells in vitro, and inhibitory activity against Topo I was evaluated by molecular biologic method.

RESULTS AND CONCLUSION

The result indicated that the yield of camptothecin glycosides by phase transfer catalysis is much higher than by the method from literature, camptothecin glycosides have much lower cytotoxicities on cancer cell in vitro, but have better inhibitory activity of topo I.
