Synthesis, cytotoxicity and antiviral activity of podophyllotoxin analogues modified in the E-ring.
Several podophyllotoxin derivatives modified in the E-ring were prepared and evaluated for their cytotoxicity on four neoplastic cell lines (P-388, A-549, HT-29 and MEL-28) and for their antiherpetic activity against Herpes simplex virus type II. The trimethoxyphenyl moiety was oxidized to ortho-quinone and further condensed with diamines and enamines to form different heterocycles. Most of the compounds maintained their cytotoxicity at the muM level and some of them showed antiherpetic activity.
