title: Use of cluster analysis in the development of structure-activity relations for antitumor triazenes.
abstract: A series of antitumor triazenes in which the members of the series are physicochemically distinct was designed using the cluster analysis approach as proposed by Hansch and his co-workers. The series that resulted was tested against Sarcoma 180 in the mouse and the antitumor activities were analyzed using regression techniques. The structure-activity relations that resulted are discussed in terms of proposed mechanisms of action.
