The synthesis of several acridinic thioethers is described. Compounds prepared were tested in vitro as potential drugs against the opportunistic infection known as cryptosporidiosis. With a view to predict activity, the quantitative structure-activity relationships were investigated. Correlations between experimental data and either log P or pKa are discussed.
A set of 9-thioalkylacridinones, has been prepared and investigated "in vitro" against T. cruzi. Structure-antiparasitic activity relationships are detailed with a view to identify the major structural parameters for the activity under consideration.
New acridinonic derivatives, which are hydroxy- and methoxy-substituted in positions 1, 4, and 1,4 were prepared with a view to obtain antiparasitic drugs. These compounds were tested against Trypanosoma cruzi strains and their capability of interacalation into DNA was determined. Nucleus substitutions, DNA binding, and trypanocidal activities have been correlated.
Synthesis and antiparasitic activity vs T. cruzi and L. donovani of a series of 9-thioaryl acridines are reported. A convenient correlation between molecular structure and biological activity is proposed. Results not only agree with the classical interactions of acridines with DNA but also suggest possible role of charge transfer complexes.
