Synthesis and antitumor activity of 20-O-linked nitrogen-based camptothecin ester derivatives
摘要:
A series of nitrogen-based 20S-hydroxyl camptothecin ester derivatives were prepared. 3-Aminopropionate of camptothecin was found more cytotoxic in vitro on several human tumor cell lines than 3-amidopropionate of camptothecin. Ester 16 showed best antitumor activity in vivo and in vitro in all esters we prepared. (C) 2004 Elsevier Ltd. All rights reserved.
