Abstract: | The new 4beta-amido analogues of podophyllotoxin or 4'-O-demethylepipodophyllotoxin have been prepared either by the coupling of 4beta-amino podophyllotoxin or 4beta-amino-4'-O-demethyl epipodophyllotoxin with the corresponding acids in presence of DCC in dichloromethane or by treating the appropriate acid chloride or sulphonyl chloride in presence of Et(3)N. These 4beta-amido and 4beta-sulphonamido derivatives of podophyllotoxin have been evaluated for their cytotoxicity against six human cancer cell lines. Some of these analogues have shown promising anticancer activity. |
