title: Complex evaluation of the effect of some cytostatic hexitol derivatives.
abstract: The antitumor effect of three structurally closely related alkylating hexitol derivatives (DBD, DAG, DiacDAG) was evaluated using a complex multi-parameter evaluation system. It comprised toxicology, action on ascites and solid tumors, as well as on subpopulations isolated by isopyknic centrifugation, cross-resistance and their action on chromatin components (DNA, histone, nonhistone proteins). The results indicate that in spite of their same mode of action, considerable differences could be observed in tumor specificity, inhibition of tumor growth and in their interaction with chromatin components. This multiparameter system seems to be very useful for comparative studies of other alkylating agents, especially for the evaluation of the effect of chemically closely related compounds.
