Ds. Vanvliet et al., Antitumor agents. 207. Design, synthesis, and biological testing of 4 beta-anilino-2-fluoro-4 '-demethylpodophyllotoxin analogues as cytotoxic and antiviral agents, J MED CHEM, 44(9), 2001, pp. 1422-1428
2-Fluoropodophyllotoxin (11) and several 4 beta -anilino-2-fluoro-4 ' -O-de
methyl analogues were synthesized and evaluated in both antineoplastic and
antiviral assays. These compounds were moderately active against some cance
r cell lines, but they were less active than the corresponding nonfluorinat
ed analogues. Compound 11 exhibited the best activity against KB carcinoma
with a GI(50) Of approximately 30 nM. Most compounds exhibited moderate act
ivity against HCMV with ID50 and ID90 values in the range of 1 muM and 4 mu
M, respectively. Both 9 and 11 showed an unusual 10-fold selectivity for HS
V-2 compared to HSV-1.
