7-Silylcamptothecins (silatecans): A new family of camptothecin antitumor agents
摘要:
The synthesis and biological evaluation of about one dozen 7-silylcamptothecin derivatives are described. Most new compounds show potencies comparable to or better than camptothecin itself. The best compound, 11-fluoro-10-amino-7-trimethylsilylcamptothecin, is more than 20 times more potent than camptothecin in cell assays. (C) 1997 Elsevier Science Ltd.
