title: Novel carbamate derivatives of 4-beta-amino-4'-O-demethyl-4-desoxypodophyllotoxin as inhibitors of topoisomerase II: synthesis and biological evaluation.
abstract: A novel series of carbamate derivatives of 4-beta-amino-4'-O-demethyl-4-desoxypodophyllotoxin were synthesized. Their effect on human DNA topoisomerase II and antiproliferative activity was evaluated. Compounds 4a-c, 4g, 4j and 4k are topoisomerase II poisons that induce double-stranded breaks in DNA and exhibit increased cytotoxicity compared to etoposide.
