In the present study we have further examined the influence of some structure parameters of macrocyclic polyethers upon their anticonvulsant activity in order to determine basic pharmacophore fragments. The anticonvulsant activity was studied experimentally for 25 new macrocyclic compounds, and their structure, physico-chemical properties, electron donor factors and atom charges were calculated using programs HyperChem-ChemPlus and HYBOT. The data about atomic properties were presented as a set functions of inter-atomic distances (Program MOLTRA). The cluster analysis revealed that studied compounds represent two independent groups which differ from chemical and pharmacological viewpoints. For first group, we have found that anticonvulsant activity of macrocycles is determined by their polarizability and spatial orientation of electron donor atoms. For another cluster the correlation was found between activity and spatial orientation of two hydrophobic fragments and electron donor atoms as well
