Synthesis and biological evaluation of new 4β-anilino- and 4β-imido-substituted podophyllotoxin congeners

A series of C-4-anilino- and C-4-imido-substituted new podophyllotoxin congeners have been designed, synthesized, and evaluated for their cytotoxicity and DNA topoisomerase-II (topo-II) inhibition potential. Some of these compounds have exhibited promising in vitro anticancer and topo-II inhibition activity.
