ELECTRON-TOPOLOGICAL INVESTIGATION OF THE STRUCTURE-ANTITUMOR ACTIVITY RELATIONSHIP OF THIOSEMICARBAZONE DERIVATIVES

In the frameworks of the electron-topological method (ETM) the structu re-antitumor activity relationship was investigated for a series of th iosemicarbazone derivatives. The series included 70 compounds. Conform ational analysis and quantum-chemical calculations were carried out fo r each compound. The revealed activity feature showed a satisfactory d escription of the class of active compounds according to two different parameters P and alpha estimating the probabilities of the feature re alization in the class of active compounds (they are equal to 0.94 and 0.86, correspondingly). The results of testing demonstrated the high ability of ETM in predicting the activity investigated.
