Abstract: Some derivatives of podophyllotoxin(1), such as etoposide(12), possess antitumor activity and have been extensively used clinically[1]. Because etoposide has a less solubility in water and higher toxicity, many chemists have an interest in further studies on the modification of the C-4 substituent of 1 for its better antitumor activity. Lee Kuo-hsing, Wang Zhe-qing et al. have synthesized a series of derivatives of CA (substituted anilino)-4-deoxypodophllotoxin. The pharmaceutical tests have shown that a number of 4β-(arylamino )-4'-demethylepi-podophyllotoxin are as potent as or more potent than etoposide(12) in inhibiting the human DNA topoisomerase Ⅱ.
