Facile and efficient one-pot synthesis of 4β-arylaminopodophyllotoxins: synthesis of DNA topoisomerase II inhibitors (NPF and W-68)
摘要:
A series of 4 beta-arylamino-4'-O-demethylepipodophyllotoxins and 4 beta-arylaminoepipodophyllotoxins have been synthesized with significant stereoselectivity and improved yields by employing the methanesulphonic acid/sodium iodide reagent system. Compounds NPF, W-68 and other DNA topoisomerase II inhibitors are prepared in good to excellent yields by this method and these are active or more active than etoposide in their inhibition of the human DNA topoisomerase II.

A series of C-4 hydroxylated and halogenated anilino derivatives of epipodophyllotoxin or 4'-demethylepipodophyllotoxin have been synthesized and evaluated for their inhibitory activity against the human DNA topoisomerase II as well as for their activity in causing cellular protein-linked DNA breakage. Compounds 11-17 and 22 are more potent than etoposide in causing DNA breakage, while compounds 11-13, 15, 16, and 20 are as active or more active than etoposide in their inhibition of the human DNA topoisomerase II. The cytotoxicity in KB cells appears to have no direct correlation with their ability to inhibit DNA topoisomerase II and to cause protein-linked DNA breaks in cells.
