Abstract
This invention provides some new synthetically obtained compounds of formula I and II ##STR1## which are useful as chemical intermediates. Representative formula I or II compounds have also been shown to possess useful ranges of antitumor activity in standard laboratory animal tests. In addition, the compounds of formula I or II can be linked to monoclonal antibodies, either directly or via known linking group, as a means of selectively delivering the CC-1065 analogs (Compounds of Formula I and II) to those target cells expressing the target antigen and thus selectively eliminating those diseased cells from the animal or human. Further, the compounds of formula I and II can be linked to soluble human CD4 or a soluble human CD4 protein fragment capable of binding to the gp120 envelope protein of the human immuno-virus and thus eliminate virally infected cells.
