摘要:
This invention relates to a novel 4'-demethyl-4-epipodophylltoxin derivative of the formula: ##STR1## (wherein R.sub.1 is a lower alkyl group; X.sub.1 and X.sub.2 are each a hydroxyl group or an amino group substituted by one or two lower alkyls, provided that either one of X.sub.1 and X.sub.2 is an amino group substituted by one or two lower alkyls and the other is a hydroxyl group) and salts thereof.
